## 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-conformance-watch-50981be1
```

Example prompt: Start a 7-day conformance watch on my x402 endpoint at https://mypayments.example.com — label it 'MyAgent Payment Gateway' so the certificate has our name on it.

## When to prefer this

Choose this endpoint when you need ongoing, cryptographically signed daily conformance auditing of a specific x402 endpoint over a bounded 7-day window, especially when you need verifiable proof of compliance history, signed pass artifacts, and a permanent readable URL. Prefer this over a one-shot conformance check when you need trend data, drift detection across days, or a certificate suitable for sharing with partners or auditors.

## Known failure modes

- URL targets scvd.store hostname — refused by policy
- URL is not publicly reachable on the internet — check fails immediately
- URL uses non-default port or is not HTTPS — rejected by schema validation
- Payment not completed via x402 — endpoint returns 402 and no watch is created
- Malformed URL supplied — schema validation error before purchase
- Agent name exceeds 80 characters — rejected by schema validation

## How this service works

The Conformance Watch. A watch id and a permanent history URL, readable immediately and filling in daily for seven days: one signed pass per day carrying the verdict, every failed check and advisory by name, plus a summary deriving the days the store missed and whether the readout drifted between passes. Bounded and prepaid; ends after seven days, renews only by repurchase. Full listing: https://scvd.store/menu/conformance_watch. MCP tool: buy_conformance_watch.

## Output

Returns a JSON object containing a watch item ID, a permanent history URL that fills in daily for 7 days, a badge URL, the amount paid in USDC, a patron number, a certificate ID with issuance date, an ed25519 signature for verification, a verify URL, and the full text of the Conformance Watch deliverable. Each day's signed pass includes the verdict, every failed check and advisory by name, and a summary noting any days the store missed and whether the readout drifted between passes.
