Delx Commerce X402 Network Match
x402
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.

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).
Example use cases
Pre-payment network compatibility check
“Before I send a micropayment, check if 'eip155:8453' is one of the supported networks in this list: ['eip155:8453', 'eip155:137'] — I need to know if it's a match.”
Agent wallet network validation
“My wallet is on network 'eip155:1' and the supported networks for this x402 API are ['eip155:8453', 'solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp']. Can you check if there's a match?”
Multi-chain payment routing decision
“I'm trying to route a payment and need to know if 'eip155:137' is in the accepted networks list of ['eip155:8453', 'eip155:42161']. Run a network match check and tell me if it passes.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/x402-network-match?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
