# Delx Commerce — X402 Settlement Network Check

> Delx Commerce — X402 Settlement Network Check is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).

Validates whether a given settlement network matches the accepted network in an x402 payment flow, returning a pass/fail result with verifiable evidence.

## Facts

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-network-check-29f51559 -d '<json body>'
```

Example prompt: Check whether the x402 settlement network 'eip155:8453' matches the accepted network 'eip155:8453' and tell me if they're compatible.

## When to prefer this

Use this endpoint when you need a lightweight, verifiable, pay-per-call check that two x402 settlement network identifiers agree before committing to a payment flow. Prefer it over manual string comparison when you need cryptographic evidence (SHA-256 input hash) and a structured audit trail that no data was retained or external calls were made.

## Known failure modes

- Mismatched networks return status 'fail' with matched=false
- Malformed or missing network strings may cause validation errors
- Overly long input strings (beyond 8192 chars) may be rejected
- Invalid network format strings may not parse correctly

## 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 a 'result' field containing the matched boolean, actual and expected network strings; a 'status' field ('pass' or 'fail'); and an 'evidence' object with a SHA-256 hash of the input, confirmation that no data is retained, and a count of external calls made (always 0).
