With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability scvd-general-store-aura-walk-x402-door-audit-17971c92 ``` Example prompt: Can you commission an aura walk on my x402 door at https://myapi.example.com/premium — have the keeper walk it cold, note that it's a JSON data endpoint requiring a 150 USDC payment, and put the certificate under the name 'Acme Agent'? ## When to prefer this Choose this endpoint when you need a human-conducted, signed, evidence-backed audit of an x402 payment door rather than a purely automated conformance check. It is the right choice when you need a certificate with an ed25519 signature for due diligence, client assurance, or go-live validation, and when a 168-hour SLA is acceptable. Prefer the free conformance check endpoints on scvd.store for quick automated checks; use this paid aura walk when you need full transcripts, a patron badge, and a portable signed certificate. ## Known failure modes - Refused if the supplied URL is scvd.store's own hostname - Refused if callback_url is invalid, uses credentials, or points to own host - Payment settlement failure leaves no order minted - URL is unreachable or not publicly accessible — keeper cannot walk it - SLA of 168 hours may elapse without completion if keeper is unavailable - Invalid or non-x402 URL may result in an inconclusive or negative audit report ## How this service works scvd.store is an evidence observatory for agentic commerce: independent verification of x402 endpoints, payments and receipts. Before an agent pays an x402 endpoint, we check that it can be paid. After it pays, we check the signed receipt. Over time we watch endpoints and publish a dated, signed corpus. Sellers use it to prove a door works; buyers use it before spending. Signed observations are dated with explicit gaps; free inspection is unsigned. Not escrow, not a rating, not a guarantee. ## Output Returns a queued order object containing an order_id, cert_id, badge_url, order_url, verify_url, patron_number, paid_usdc amount, SLA of up to 168 hours, and an ed25519 signature. The completed order (polled via order_url) will carry the full audit report with keeper transcripts attached. A signed certificate is accessible via verify_url once the walk is complete. ## 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 door: https, default port, on the public internet — the URL a buyer would GET expecting a 402.
