• find_similar_moments

  Find historically similar audience moments across the screen network using embedding similarity search. Input a natural-language description of the target moment. Moment embeddings are 768-D vectors generated from multi-modal observation data (visual, audio, environmental, social) via the MomentEmbeddingService. This tool embeds your query text and finds the closest real-world moments via approximate nearest-neighbour (ANN) cosine similarity over a Lance IVF_PQ index. CONSISTENCY: results are APPROXIMATE and EVENTUALLY CONSISTENT. - Approximate: retrieval is ANN, not an exhaustive scan (measured recall ~0.96 against exact KNN), so an identical query may omit a borderline match. - Eventually consistent: the index is served from a replicated pool whose replicas refresh independently, so for up to 5 minutes after new moments are published, two identical calls may return slightly different result sets. The difference is confined to the VISIBILITY of newly-published moments; the relative ranking of already-visible ones does not change. Do not use this tool where a repeatable, exhaustive result set is required. WHEN TO USE: - Searching for historical moments similar to a target scenario - Finding "moments like this one" across different venues/times - Discovering when similar audience compositions or behaviors occurred - Planning ad placements based on past similar contexts RETURNS: - data: Array of matching observations with similarity scores - observation_id, observed_at, venue_type, device_id, screen_mongo_id - payload: full observation data - evidence_grade: quality of observation - similarity: cosine similarity score (0-1, higher = more similar) - metadata: { result_count, embedding_model, min_similarity_threshold } - suggested_next_queries: Follow-up queries EXAMPLE: User: "Find moments with high engagement in evening restaurants with families" find_similar_moments({ query: "evening restaurant venue with families present, high emotional engagement and attention" }) User: "When did we see young adults highly engaged at transit screens?" find_similar_moments({ query: "transit venue morning commute young adults high attention" })

• get_products

  [AdCP Media Buy] Get available DOOH advertising products and packages. NO AUTHENTICATION REQUIRED. Discovery is open — read the catalogue first, get a key when you want to transact. Send a natural-language `brief` and it is answered from what the screens actually observed: each product's `description` reports the hours people are really in frame (in the screens' own local time), how long they dwell, the mood / movement / gaze the on-device sensors reported, what the speech layer heard people shopping for — and, explicitly, which of your words we cannot evidence. Products are ordered by that evidence. WHEN TO USE: - Browsing available inventory before creating a campaign - Comparing pricing across venue types and locations - Understanding what's available in a specific market, at a specific time of day RETURNS: - products: Array of product packages with pricing, reach, and observed audience - Each product includes: name, description (free text answering your brief), venue_type, screen_count, pricing_options, and `observed` — the numbers behind the prose, present only where we measured something - brief_interpretation: how we read your brief, so you can see if we read it right EXAMPLE: User: "commuters who are bored and hungry around lunchtime" get_products({ brief: "commuters who are bored and hungry around lunchtime" })

• get_social_attention

  Query social attention contagion metrics from the observation stream. Returns windows where attention propagated between viewers (social amplification factor > 1). Social attention data is produced by the AttentionGraphBuilder running on CTV edge devices, which models viewer attention as a directed graph and detects when one viewer looking at the screen triggers nearby viewers to also look (attention contagion / social amplification). WHEN TO USE: - Finding moments where social proof drove collective engagement - Identifying which venues or dayparts exhibit highest attention contagion - Understanding cascading attention patterns (cascade depth) - Correlating social amplification with ad effectiveness (VAS) RETURNS: - data: Array of observation_stream rows with socialAttention payload - payload.socialAttention.socialAmplificationFactor (SAF): ratio of actual-to-expected group attention (>1 = contagion detected) - payload.socialAttention.cascadeDepth: max depth of attention propagation chain - payload.socialAttention.viralAttentionScore: composite metric combining SAF and cascade depth - payload.socialAttention.contagionWindowMs: time window over which cascade occurred - payload.socialAttention.triggerViewerIndex: which viewer initiated the cascade - metadata: { result_count, time_range, min_saf_filter } - suggested_next_queries: Follow-up queries EXAMPLE: User: "Show me moments where attention went viral in bar venues" get_social_attention({ min_saf: 2.0, venue_type: "bar" }) User: "Find the strongest social amplification events this week" get_social_attention({ min_saf: 3.0, time_range: { start: "2026-03-09T00:00:00Z", end: "2026-03-16T00:00:00Z" } })

• get_task_status

  [AdCP Protocol] Get the status of a previously issued AdCP task. Every AdCP task Trillboards serves for an AUTHENTICATED caller is recorded and returned a `task_id`. Poll that id here to read the task's terminal state and, with `include_result: true`, its completion payload. Trillboards answers every AdCP task in-process, so a task is already `completed` by the time you hold its id — this tool exists so a buyer that polls does not hang, and so an async arm has somewhere to report from when one lands. TASK SCOPE: tasks are visible only to the account that created them. An id belonging to another account, an id we never issued, or a poll with no credential all answer identically — "Task <id> not found" — so the surface cannot be used to probe which ids exist. NOT RECORDED: read-only protocol and catalogue calls that AdCP does not model as tasks (get_adcp_capabilities, list_creative_formats, get_media_buys, list_accounts), and any anonymous call, which has no account to scope to.

  [AdCP Accounts] List the accounts this credential can transact on. This seller's account model is 'explicit': one API key IS one account, so this returns exactly one account — the partner behind the key. Use it to discover your account_id before any account-scoped call, and to confirm the account's status before you buy. WHEN TO USE: - Discovering the account_id to pass to account-scoped tasks - Checking your account is 'active' before creating a media buy - Introspecting what your key is permitted to do (accounts[].authorization.allowed_tasks) RETURNS: - accounts: AdCP Account objects (account_id, name, status, operator, brand, billing, account_scope) plus an authorization object naming the tasks this key may invoke - pagination: has_more is always false — one credential, one account EXAMPLE: list_accounts({}) list_accounts({ status: "active" })

• list_creative_formats

  [AdCP Media Buy] List the creative formats this network actually accepts. Every format is DERIVED from live per-screen capability (panel size, min/max spot length, audio) — not a hand-written list. The set published here is exactly the set sync_creatives accepts: if a creative matches a format returned by this tool, it will not be rejected for dimensions, duration or file size. WHEN TO USE: - Before building creative, to size it to the panels you are buying - To check whether an existing asset can run on this network - To find the panel sizes with the most reach (results are ordered by live screen count) RETURNS: - formats: AdCP Format objects (format_id, name, renders[].dimensions, assets[].requirements) - pagination: cursor-based; total_count is the full catalogue size - Each format carries ext.trillboards with the live screen count, the share of the network, how many of those screens have audio, and — for video — duration_coverage: how many screens accept a spot of at most 10/15/20/30/60/120/300 seconds. A long ceiling does not mean every screen at that size can play it, and this says so. EXAMPLE: User: "What sizes and lengths does this network take?" list_creative_formats({ pagination: { max_results: 20 } }) User: "Can I run a 1080x1920 portrait video?" list_creative_formats({ format_ids: [{ agent_url: "https://api.trillboards.com/mcp", id: "dooh_video_1080x1920" }] })

• list_creatives

  [AdCP Creative] List the creatives this buyer has on file with us. OUR LIBRARY IS PER-BUY, AND THIS SAYS SO. AdCP's creative library models concepts, variables, assignments and snapshots; ours does not have those. A creative here is the one asset attached to a media buy by sync_creatives, so this is a projection of YOUR OWN buys — never someone else's assets, and never an invented concept_id to look richer than we are. WHEN TO USE: - To confirm a creative you sent actually landed, and where it is in review - To see which media buy a creative is attached to (include_assignments: true) - Before cancelling a buy, to check what happens to its creative RETURNS: - creatives[]: creative_id, name, format_id ({agent_url, id}), status, created_date, updated_date. Status is 'pending_review' until the buy is servable, then 'approved' — every creative goes through the same moderation every other creative on this network goes through. - query_summary: total_matching + returned - pagination: cursor-based, with total_count EXAMPLE: User: "Did my creative go through?" list_creatives({ filters: { media_buy_ids: ["mbuy_123"] }, include_assignments: true })

• semantic_search_observations

  Search observations by semantic similarity. Find moments that match a description like "lunch rush at fast casual restaurants" using vector embeddings. Uses 768-dimensional Gemini embeddings on observation payloads to find promoted observations matching a natural language query via approximate nearest-neighbour (ANN) cosine similarity search over a Lance IVF_PQ index. CONSISTENCY: results are APPROXIMATE and EVENTUALLY CONSISTENT. - Approximate: retrieval is ANN, not an exhaustive scan (measured recall ~0.96 against exact KNN), so an identical query may omit a borderline match. - Eventually consistent: the index is served from a replicated pool whose replicas refresh independently, so for up to 5 minutes after new observations are published, two identical calls may return slightly different result sets. The difference is confined to the VISIBILITY of newly-published observations; the relative ranking of already-visible ones does not change. Do not use this tool where a repeatable, exhaustive result set is required. TIME BOUND: searches the last 30 days by default. Pass filters.time_range to widen or narrow it; the window actually applied is echoed in metadata.time_range. Observations are retained for 90 days. WHEN TO USE: - Finding observations that match a conceptual description - Discovering contextual moments across the screen network - Searching for audience situations ("families waiting in line", "professionals on coffee break") - Finding commerce patterns ("high purchase intent near checkout") RETURNS: - data: Array of matching observations ranked by semantic similarity, each with: - observation_id, device_id, venue_type, observation_family - observed_at, payload, confidence, evidence_grade - similarity: Cosine similarity score (0-1, higher = more relevant) - metadata: { result_count, query_embedding_model, search_scope, time_range } - suggested_next_queries: Related semantic queries to explore EXAMPLE: User: "Find lunch rush moments at fast casual restaurants" semantic_search_observations({ query: "lunch rush at fast casual restaurants with high foot traffic", filters: { venue_type: ["restaurant_qsr"] }, limit: 20 }) User: "Find moments with high emotional engagement" semantic_search_observations({ query: "audience showing strong positive emotional reactions", filters: { observation_family: ["audience"] }, limit: 10 })

  shallow
• sync_accounts

  [AdCP Accounts] Establish or confirm the account behind this credential. IMPORTANT — what this does NOT do: it does not provision a new account. This seller's namespace is one account per API key, so a provisioning-mode entry (brand + operator + billing) is LINKED to the account your key already owns and the response says so in warnings[]. Two different brands on one key resolve to the SAME account_id. Register one agent per brand at https://api.trillboards.com/v1/partner/agent/register if you need per-brand separation. BILLING IS THE ONE SETTING THAT IS APPLIED. Send billing: 'operator' (we invoice you, buying direct) or 'agent' (you are a buying agent consolidating across the brands you front, and we invoice you for all of them — the marketplace-clearing model). The value is stored on the account, reported back by list_accounts, and reflected in action 'updated'. The set we accept is exactly account.supported_billing from get_adcp_capabilities; 'advertiser' is refused, with the reason, because we hold no billing relationship with a third-party advertiser. One key is one account with one invoiced party, so a request declaring two different billing values applies neither and says so. Everything else is read-only and reports 'unchanged': payment terms, billing entity and notification subscriptions are not per-account state on this platform, and anything sent that was not applied is named in warnings[] rather than silently swallowed. WHEN TO USE: - The account-setup step at the start of a buying flow - Declaring how you want to be invoiced, before create_media_buy - Confirming your account_id and status before create_media_buy RETURNS: - accounts: per-entry result with account_id, action ('updated' | 'unchanged' | 'failed'), status, billing, account_scope, and warnings naming anything not applied EXAMPLE: sync_accounts({ idempotency_key: "8f1c...", accounts: [{ brand: { domain: "acme.example" }, operator: "agency.example", billing: "agent" }] })

WHEN TO USE: - Submitting creative assets before campaign launch - Checking if a creative meets screen requirements - Validating VAST tags EXAMPLE: sync_creatives({ media_buy_id: "mbuy_abc123", creatives: [{ url: "https://cdn.example.com/ad.mp4", type: "video", width: 1920, height: 1080, duration_seconds: 15, file_size_mb: 12 }] })

• tasks_get

  [AdCP Protocol] Get the status of a previously issued AdCP task. Every AdCP task Trillboards serves for an AUTHENTICATED caller is recorded and returned a `task_id`. Poll that id here to read the task's terminal state and, with `include_result: true`, its completion payload. Trillboards answers every AdCP task in-process, so a task is already `completed` by the time you hold its id — this tool exists so a buyer that polls does not hang, and so an async arm has somewhere to report from when one lands. TASK SCOPE: tasks are visible only to the account that created them. An id belonging to another account, an id we never issued, or a poll with no credential all answer identically — "Task <id> not found" — so the surface cannot be used to probe which ids exist. NOT RECORDED: read-only protocol and catalogue calls that AdCP does not model as tasks (get_adcp_capabilities, list_creative_formats, get_media_buys, list_accounts), and any anonymous call, which has no account to scope to. LEGACY NAME. Identical to `get_task_status`; this is the name the AdCP MCP binding emits (`agent.protocol === "mcp" ? "tasks_get" : "tasks/get"`). Prefer `get_task_status` in new code.

• tasks_list

  [AdCP Protocol] List AdCP tasks belonging to your account, newest first. Returns `query_summary` (totals and a status breakdown), `tasks`, and `pagination`. Filter by status or task type. Scoped to the calling account — an unauthenticated call returns an empty page rather than another account's tasks. LEGACY NAME. Identical to `list_tasks`. Prefer `list_tasks` in new code.

• test_webhook

  Send a test event to a webhook endpoint. WHEN TO USE: - Verifying webhook endpoint is working - Testing integration during development - Debugging webhook delivery issues RETURNS: - success: Boolean indicating delivery success - response_code: HTTP response code from endpoint - response_time_ms: Response time in milliseconds - error: Error message if delivery failed EXAMPLE: User: "Test my webhook with a device.online event" test_webhook({ webhook_id: "wh_mmmpdbvj_8b7c5a59296d", event: "device.online" })

  shallow
• update_media_buy

  [AdCP Media Buy] Update an existing media buy (campaign). Modify budget, targeting, schedule, or status of an existing media buy. WHEN TO USE: - Adjusting campaign budget mid-flight - Pausing or resuming a campaign - Changing targeting parameters - Extending campaign dates EXAMPLE: update_media_buy({ media_buy_id: "mbuy_abc123", updates: { status: "paused", budget: { daily_usd: 300 } } })

  shallow
• update_webhook

  Update an existing webhook subscription. WHEN TO USE: - Changing the webhook endpoint URL - Adding or removing subscribed events - Enabling or disabling a webhook - Updating the webhook description RETURNS: - webhook_id: The updated webhook ID - url: Updated endpoint URL - events: Updated event subscriptions - enabled: Updated enabled status - updated_at: Update timestamp EXAMPLE: User: "Disable the webhook for maintenance" update_webhook({ webhook_id: "wh_mmmpdbvj_8b7c5a59296d", enabled: false }) User: "Add impression events to my webhook" update_webhook({ webhook_id: "wh_mmmpdbvj_8b7c5a59296d", events: ["device.online", "device.offline", "impression.recorded"] })

  shallow
• validate_request

  Validate a proposed request payload against the registered Zod schema for an operation, returning the exact canonical error envelope the HTTP surface would emit. WHEN TO USE: - Before calling a write endpoint, to catch payload bugs locally. - Debugging 400 validation_error responses. RETURNS: - valid: true when the payload would pass Zod validation. - When invalid, the canonical { error: { type, code, message, param, doc_url, details[] } } envelope is included under `error`. EXAMPLE: validate_request({ path: "/v1/data/query", method: "POST", payload: { dataset: "inference_outcomes", limit: 9999 } })

  shallow
• verify_proof_of_play

  Verify cryptographic proof of ad delivery or get campaign proofs. Requires either campaign_id or proof_payload (at least one must be provided). Two modes: 1. Verify a proof: pass proof_payload with signature fields to verify 2. Get proofs: pass campaign_id to get Ed25519-signed proofs for a campaign Uses Ed25519 signatures (v2) that can be independently verified by third parties using the Trillboards public key. WHEN TO USE: - Verifying that ads were actually delivered to screens - Exporting cryptographically signed proof records for auditors - Getting proof-of-play data for campaign transparency reports RETURNS (verify mode): - valid: boolean, reason: string if invalid, version: 'v1' or 'v2' RETURNS (get proofs mode): - campaignId, totalImpressions, proofsReturned - proofs: Array of signed impression proofs - pagination: { limit, hasMore, nextCursor } - signatureVersion, publicKeyUrl EXAMPLE (verify): verify_proof_of_play({ proof_payload: { signature: "ed25519=abc123...", timestamp: "2026-03-10T15:30:00Z", adId: "ad_123", impressionId: "imp_456", screenId: "scr_789", deviceId: "dev_012" } }) EXAMPLE (get proofs): verify_proof_of_play({ campaign_id: "camp_abc123", start_date: "2026-03-01", end_date: "2026-03-10" })
