Purpose: record what an agent is authorized to do BEFORE it spends — the claimed instructions verbatim, who submitted them (agent or principal, itself a claim), an optional declared cap in USDC and expiry — as a signed, dated record held by a party that is neither the agent nor its principal, at a free permanent URL, with a mandate_id every later purchase here can cite; a citation that does not resolve is refused before any charge, so it always lands signed on the citing certificate. A second party can counter-sign the record free with its own ed25519 key. Chain-of-custody, never truth-of-intent: the cap and expiry are declared and never enforced. Schema /schemas/scvd-mandate-v1.json; the pattern for other issuers at /mandate-spec. Every item on this shelf is $0.1. Items on this shelf (pass one as item_id): - the_mandate: The Mandate, $0.1 fixed, one-off, instant. Record what my agent is authorized to do, dated and signed by a third party, before it spends anything On cadence, for all of the above: nothing here charges again by itself, ever — there is no mechanism that could. Required beyond item_id: the_mandate needs mandate. Other items need only item_id. Choose item_id. instant items return deliverable, cert_id and patron_number in one call. x402 payment: _meta['x402/payment']. Without payment: error 402 with the terms in error.data. Closed or empty shelves refuse before quoting. Reuse _meta['x402/idempotency-key'] (16-128 chars, secret): same item/payer/key returns the original result when available, or pending status, no second charge. Use idempotency.suggested_key only without an earlier key. A fresh payment without a key can charge again. Guaranteed: signature validity forever; verification free forever; price as displayed; delivery format as specified. Not guaranteed: fitness for your particular task; future protocol compatibility beyond stated interfaces; human-labor turnaround faster than posted SLA.
