Third-party monitors may report differently. ## How to call it through Zero Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability scvd-general-store-x402-trust-profile-75a6c2df ``` Example prompt: Get me a signed x402 trust certificate from SCVD General Store for my endpoint at https://myapi.example.com/goods — put it in the name of 'MyAgent v1' and note that the purpose is to establish standing for agentic commerce. ## When to prefer this Choose this endpoint when you need a cryptographically signed, third-party-issued trust certificate for an x402 endpoint that can be independently verified — particularly when listing on x402 marketplaces, onboarding new merchant agents, or providing downstream agents with auditable proof of x402 conformance. Prefer this over self-attested claims or informal checks when the certificate's 30-day standing, patron badge, and Bitcoin-anchored audit trail matter to your trust model. ## Known failure modes - Endpoint URL fails x402 preflight checks — refused before payment, no certificate issued - URL uses non-standard port or is not on the public internet — rejected at validation - Supplied URL is scvd.store's own hostname — explicitly refused - Endpoint is unreachable at time of purchase — rejected with not_ready or unreachable verdict - Malformed URL format — schema validation error before processing - Payment settlement fails on Base/Polygon/Arbitrum/World/Solana — no certificate minted ## How this service works The Hosted Profile. REQUIRES ?url= on the paid request — a signed request without it is refused before the gate and no money moves. A standing page about your endpoint at this store's domain for 30 days per purchase, renewable: your live endpoint passport, the freshness chip, and the signed per-host observation history, aggregated at one URL an operator can hand to anyone. The commission record is signed and its evidence hash bound into your purchase certificate. Never a ver… ## Output Returns a signed JSON payload containing: a trust certificate with cert_id, date, patron number, and item type; an ed25519 signature over the certificate; a hosted trust profile as plain text; a badge SVG URL; a verify URL for third-party confirmation; and the USDC amount paid. ## Request schema (JSON Schema) ```json { "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "input" ], "properties": { "input": { "type": "object", "required": [ "type", "method" ], "properties": { "type": { "type": "string", "const": "http" }, "method": { "enum": [ "GET" ], "type": "string" }, "queryParams": { "type": "object", "required": [ "url" ], "properties": { "url": { "type": "string", "format": "uri", "description": "Your own x402 endpoint: https, default port, on the public internet, and on the ready side of the census's latest evidence — a failing door is refused before any money moves.
