# Delx Commerce — X402 Delivery Status Check

> Delx Commerce — X402 Delivery Status 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).

Checks whether a given HTTP status code is considered an accepted/successful delivery status within the x402 payment protocol context

## 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-delivery-status-check-2d01321f -d '<json body>'
```

Example prompt: Check if HTTP status 200 counts as an accepted delivery — use accepted statuses 200 and 201 — and give me the full verification result with evidence.

## When to prefer this

Use this endpoint when you need a verifiable, tamper-evident check of whether an HTTP status code qualifies as a successful delivery within the x402 micropayment protocol — particularly when you need cryptographic evidence (SHA-256 input hash, no-retention proof) for auditing or dispute resolution. Prefer this over a local if-statement check when you need an on-chain-verifiable or third-party-auditable delivery confirmation.

## Known failure modes

- Invalid or missing 'status' field returns a validation error
- Accepted statuses array exceeding 256 items is rejected
- Non-integer status codes cause schema validation failure
- Empty accepted_statuses array results in accepted=false for any input

## 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: the input status and whether it was accepted, the list of accepted statuses, a pass/fail status field, an operation identifier ('delivery_contract:x402_delivery_status_check'), and a cryptographic evidence block with an input SHA-256 hash, confirmation of no data retention, and zero external calls made during processing.
