How this service works
The Mandate. REQUIRES ?mandate= on the paid request — a signed request without it is refused before the gate and no money moves. A signed JSON mandate record — the claimed instructions verbatim, submitted_as (agent or principal, itself a claim), declared_cap_usdc and expires_at where given (declared, never enforced), dated, its evidence hash bound into the purchase certificate's attests field — plus a stable mandate URL serving the record free forever, and a mandate_id every…
Output
A signed JSON mandate record containing: the verbatim claimed instructions, submitted_as field, declared_cap_usdc and expires_at (where provided), a timestamp, an evidence hash bound into the purchase certificate's attests field, a stable permanent mandate URL serving the record for free, and a unique mandate_id that future purchases on scvd.store can cite (the store refuses purchases citing an unresolvable mandate_id, so the citation is always verifiable).
Example use cases
Pre-flight mandate registration for autonomous agent
“Before this agent starts making purchases, record its mandate: 'Authorized to buy weather data and news summaries, max $2 USDC per call, for research pipeline v3.' Submit it as agent, declared cap 2 USDC, expiry 2026-01-01, and give me the mandate_id so every purchase can cite it.”
Human principal attesting agent scope
“I'm the principal and I want to formally record what I've authorized my agent to do: 'Fetch and summarize daily SEC filings, no purchases above $0.50 USDC.' Submit this as principal, with my agent named 'FilingsBot', expiry 2025-09-30, and return a signed certificate with a stable URL.”
Audit trail for a deployed agent fleet
“Create a signed mandate record for our content-moderation agent — instructions: 'Review and flag user-submitted text for policy violations; no outbound messaging permitted.' No spending cap, submitted as agent, agent name 'ModBot-7', so we have a timestamped chain-of-custody record if we're ever audited.”
Technical details
Endpoint
GEThttps://scvd.store/api/buy/the_mandate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a signed, timestamped, permanently accessible chain-of-custody record of an AI agent's claimed instructions — especially before the agent begins making autonomous purchases or taking actions that require an auditable authorization trail. It is the right choice when you want a citable mandate_id that downstream x402 purchases on scvd.store can reference. Prefer it over generic logging when you need cryptographic signing, a stable public URL, and integration with the x402 agent economy's trust layer.
Side effects
- mandate text exceeds 2000 characters — request rejected
- unresolvable mandate_id cited in a subsequent purchase — that purchase refused
- missing required 'mandate' query parameter — error returned
- submitted_as enum value not 'agent' or 'principal' — validation error
- declared_cap_usdc or expires_at malformed — field-level validation error
- payment of 0.1 USDC not completed via x402 — no record created
