# Delx Commerce X402 Network Match

> Delx Commerce X402 Network Match 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 blockchain network (e.g. eip155:8453) is supported by a list of accepted networks, returning a boolean match result with cryptographic evidence of processing.

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-network-match-1c3a633b -d '<json body>'
```

Example prompt: Check whether the network 'eip155:8453' matches any of my supported networks ['eip155:8453', 'eip155:1'] using the Delx x402 network match utility.

## When to prefer this

Use this endpoint when you need a verifiable, cryptographically-evidenced check that a specific blockchain network identifier appears in a list of supported networks — particularly in x402 payment flows where you need tamper-evident proof of the match computation without any data retention. Prefer this over a simple client-side array lookup when auditability, evidence hashing, and zero external calls matter.

## Known failure modes

- Invalid or malformed CAIP-2 network string returns an error or match:false
- Empty supported_networks array always returns matched:false
- Network string exceeding 8192 characters is rejected
- Exceeding 256 items in supported_networks array causes rejection
- Missing required 'network' field returns validation error

## 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' containing 'actual' (the network provided), 'matched' (boolean), and 'supported' (matched networks). Also includes 'status' (pass/fail), 'schema' identifier, and an 'evidence' object with 'retained' (false — no data kept), 'input_sha256' (hash of inputs for verifiability), and 'external_calls' count (always 0, computed in-memory).
