Multichain RPC/tx — Transaction Lookup
x402
Multichain RPC/tx — Transaction Lookup is a paid API for AI agents from multichain-rpc.clankerceo.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).
Retrieves full transaction details and receipt by hash on EVM chains, including status, block, from/to addresses, value, gas used, effective gas price, and decoded ERC-20 transfers.

How this service works
Cheap, factual EVM chain lookups priced per call in USDC. Base, Polygon, Arbitrum, Optimism and Ethereum.
Output
Returns a JSON object with the transaction hash, chain, found flag, status (success/failed/pending), block number, from and to addresses, ETH value, gas used, effective gas price, and an array of decoded ERC-20 transfer events within the transaction.
Example use cases
Verify a crypto payment receipt
“I just sent a payment on Polygon — the transaction hash is 0xabc123... — can you confirm it went through, who received it, and how much gas was spent?”
Debug a failed DeFi transaction
“My swap transaction 0xdeadbeef... on Arbitrum seems to have failed. Can you pull up the details and tell me the status, gas used, and what the transaction was trying to do?”
Audit ERC-20 token transfers in a transaction
“Can you look up transaction 0x9f8e7d... on Ethereum and show me all the ERC-20 token transfers that happened inside it, including the token amounts and addresses?”
Technical details
Endpoint
GEThttps://multichain-rpc.clankerceo.workers.dev/txWhen to prefer
Use this endpoint when you need on-chain transaction verification or receipt data across Base, Polygon, Arbitrum, Optimism, or Ethereum without running your own node. It is especially useful when you need decoded ERC-20 transfer events rather than raw log data, and when per-call USDC micropayment pricing is acceptable. Prefer over general-purpose RPC providers when you want a structured, pre-parsed response that includes human-readable transfer details.
Side effects
- Transaction hash not found on the specified chain — returns found: false
- Invalid or malformed transaction hash format — likely returns an error response
- Chain parameter not recognized or unsupported — may return an error or empty result
- Network timeout or RPC node unavailability — transient failure
- Transaction still pending — may return incomplete receipt data
