# Delx Commerce — X402 Settlement Recipient Check

> Delx Commerce — X402 Settlement Recipient Check is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Verifies that a payment recipient address in an X402 transaction matches the expected pay-to address, returning a pass/fail result with cryptographic evidence.

Status and success rate cover calls made through Zero and Zero's own probes. 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 delx-commerce-x402-settlement-recipient-check-465d845f -d '<json body>'
```

Example prompt: Before we finalize this x402 payment, verify that the settlement recipient address 0xABCD...1234 actually matches the expected pay-to address 0xABCD...1234 so we know the funds are going to the right place.

## When to prefer this

Choose this endpoint when you need lightweight, stateless, in-memory verification that an x402 payment's recipient address matches the expected pay-to address — especially in agent pipelines where you want cryptographic evidence (SHA-256 input hash) and a guarantee of no data retention or external calls. Prefer it over manual address comparison when you need an auditable, structured pass/fail record for compliance or logging purposes.

## Known failure modes

- Address format mismatch (invalid hex string or non-address value) may cause a validation error
- If pay_to or recipient fields are missing, the endpoint may return an error or automatic fail status
- A 'matched: false' result with status 'fail' indicates a legitimate address mismatch rather than an API error
- Network or service unavailability returns a non-200 HTTP status

## 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 containing a 'result' block with the actual recipient address, the expected address, and a boolean 'matched' field; a top-level 'status' field ('pass' or 'fail'); an 'evidence' block with a SHA-256 hash of the input, a flag confirming no data retention, and confirmation of zero external calls made; plus schema and operation identifiers for auditability.
