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 indicating whether the two chain IDs matched, the actual and expected chain IDs, a pass/fail status, and a verifiable evidence object including an input SHA-256 hash and confirmation that no data was retained or external calls made.
Example use cases
Guard against wrong-network transactions
“I'm about to submit a transaction with chain ID 1, but I expected it to go to Base (chain ID 8453) — can you run a chain match check to confirm whether they're the same network before I proceed?”
Preflight check in automated agent workflow
“Before my agent submits the on-chain step, verify that the transaction's chain ID 137 matches the expected Polygon chain ID 137 so we don't accidentally hit the wrong network.”
Debugging a failed blockchain submission
“A transaction I sent seems to have gone to the wrong chain — can you check if chain ID 56 matches the expected chain ID 8453 and tell me whether there was a mismatch?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/evm-chain-match-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, stateless, pay-per-call EVM chain ID comparison with cryptographic evidence of the computation — especially in agent workflows requiring auditable preflight checks before submitting on-chain transactions. Prefer it over home-grown comparisons when verifiability, no-signup simplicity, and USDC micropayment pricing matter.
Side effects
- Missing required fields (expected_chain_id or transaction_chain_id) results in a validation error
- Non-integer chain ID values cause schema rejection
- Payment failure (insufficient USDC balance or x402 protocol error) blocks the request
- Network timeout or service unavailability returns a 5xx error
