## 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 delx-commerce-base-settlement-receipt-check-ba6087a7 -d '<json body>'
```

Example prompt: Check whether this Base settlement receipt is valid — the expected recipient is 0xAbC123...def and the expected raw amount is 1000000 — and tell me if the chain, amount, and recipient all match.

## When to prefer this

Use this endpoint when an AI agent needs to programmatically verify that a Base blockchain settlement receipt matches expected payment parameters (recipient address and raw amount) before releasing a resource, fulfilling a request, or logging a confirmed transaction. Prefer it over manual onchain lookups when you want a structured, deterministic pass/fail response with an auditable input hash and zero data retention, especially in x402 pay-per-result agent pipelines on Base.

## Known failure modes

- Malformed or missing receipt object returns a validation error
- Expected recipient or amount mismatch results in pass=fail with false match flags
- Overly large receipt object (>128 properties) may be rejected
- Network errors on the x402 payment layer return a 402 before the check runs
- Invalid USDC amount format in expected_amount_raw may cause parsing failure

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object with boolean fields for chain_match, amount_match, recipient_match, and status_success, plus an overall pass/fail status string. Also includes an evidence block with retained=false, a SHA-256 hash of the input, the count of external calls made (0), and the operation identifier. Onchain_verified is included but may be false for preflight checks.
