Tools

• apihub_balance

  Read-only. Returns your current APIHub credit balance (in microdollars and USD), total lifetime spending (microdollars and USD), and total completed request count. Requires a valid API key. Use before apihub_call or apihub_call_external to confirm sufficient funds for a paid request, or periodically to audit usage. Does not modify state, send payments, or call upstream APIs; for top-ups use apihub_topup.

  shallow
• apihub_call

  Sends payment. Calls a paid endpoint on an onboarded APIHub service. Debits the endpoint's price from your credit balance and forwards the request to the upstream provider. Returns an object with the upstream response body, HTTP status, and credits_charged_microdollars. Requires a valid API key and sufficient credit balance; if balance is insufficient the call returns a 402 with payment requirements (use apihub_topup to add credits, apihub_balance to check). Use this for services already onboarded to APIHub (find slugs via apihub_search or apihub_list_services); use apihub_call_external for arbitrary x402 URLs not onboarded here, or apihub_read_content for content gateways.

  shallow
• apihub_call_external

  Call an external x402-protected URL (any provider in the marketplace or any x402 API). APIHub pays the provider on your behalf using the platform wallet and debits your credit balance for the exact amount. No wallet or gas required.

  shallow
• apihub_get_service

  Get full details for a specific API service including all endpoints, schemas, and pricing.

  shallow
• apihub_list_services

  Read-only. Lists onboarded APIHub services alphabetically, returning each service's slug, name, description, category, provider, endpoint count, and lowest per-endpoint price in microdollars. No authentication required. Use this to browse the full onboarded catalog when you don't have a specific capability in mind; prefer apihub_search when filtering by query, category, or price. Does not include external x402 APIs (use apihub_search_external for those) and does not return endpoint-level details (use apihub_get_service for that).

  shallow
• apihub_read_content

  Read web content through a paid content gateway. Returns clean, structured text extracted from the URL. Use this for content services (service_type = 'content').

  shallow
• apihub_search

  Read-only. Searches onboarded APIHub services by free-text query, with optional category, price, and type filters. Returns up to 10 matches ranked by uptime and endpoint count, each with slug, description, endpoints array, min price in microdollars, provider name, and quality score. No authentication required. Use this when you need to find an API by capability; use apihub_list_services to browse without a query, apihub_search_external to include the external x402 catalog, or apihub_get_service when you already know a slug. Does not call any upstream API or debit credits.

  shallow
• apihub_search_external

  Search external x402-protected APIs (not operated by APIHub, but callable via credits). Returns listings with endpoint counts, prices, and on-chain activity.

  shallow
• apihub_topup

  Purchase APIHub credits via x402 (USDC on Base). Returns payment instructions including a web URL for browser-based payment, a CLI command, and raw x402 requirements for agents with wallet support. Credits are added to your account instantly once payment confirms on-chain.
