## 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 nohumans-directory-listing-verify-now-single-purchase-54af08d9 -d '<json body>'
```

Example prompt: Trigger a single verify-now purchase for listing abc123 on nohumans.directory — use my claim token to authorize it and record whatever the verification finds publicly.

## When to prefer this

Use this endpoint when you need a real, on-the-record paid verification of a specific nohumans.directory listing — particularly when you are the listing owner and want independent evidence that your x402 payment flow works, or when you need a fresh public audit trail. Prefer the ?plan=pack option via the sister endpoint if you need three verifications within 30 days. Do not use this if you only want to read existing verification history (use the purchase history endpoint instead) or pre-spend verdict (use the pre-spend verdict endpoint).

## Known failure modes

- Missing or invalid x-claim-token header returns authorization error (owner-only endpoint)
- Invalid or non-existent listing ID returns 404 not found
- Payment failure or insufficient USDC balance causes transaction rejection
- Listing already has a pending verification within 24-hour window may return conflict
- Network or provider downtime causes 5xx server error
- Attempting to set outcome, badge, or score via request is ignored — money only controls timing

## How this service works

For owners of a listed paid API: we buy from your endpoint with real USDC and publish the result on your nohumans.directory listing, whatever it finds. Plan "single": one purchase within 24 hours. Money decides when we buy, never the outcome, score or rank. Send your claim token as x-claim-token. Fee $3.00; this listing quotes $0.5000/call. Other plan: ?plan=pack ($5, three purchases in 30 days). Rule: https://nohumans.directory/methodology#verify-now

## Output

Returns a JSON object with: the queued status of the verification request, a unique request_id, the listing_id being verified, a fee_tx reference for the $3 USDC payment transaction, a record URL where the public audit outcome will be published, a promise describing what will be recorded, and a rule URL linking to the verification methodology.
