x402
chain-transaction is a paid API for AI agents from chain.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-02).
Retrieves raw transaction details by hash (from, to, value, nonce, block, gas, type, method selector, pending flag) across Base, Ethereum, Arbitrum, Optimism, Polygon, and BSC.

How this service works
Raw transaction by hash: from, to, value, nonce, block, gas, type, method selector, pending flag. Default chain Base; prefix another: ethereum:, arbitrum:, optimism:, polygon:, bsc:. $0.01 per call.
Output
Returns a JSON object containing the raw transaction fields: sender address (from), recipient address (to), value transferred, nonce, block number, gas limit and gas used, transaction type, the 4-byte method selector (for contract calls), and a boolean pending flag indicating whether the transaction is still unconfirmed in the mempool.
Example use cases
Verify a crypto payment receipt
“I need to confirm a payment — can you look up transaction 0xa1b2c3d4e5f6... on Base and tell me the sender, receiver, value transferred, and whether it's confirmed?”
Debug a failed contract interaction
“Check the transaction 0xdeadbeef...cafe on Arbitrum — what method was called, how much gas was used, and is it still pending or already in a block?”
Audit cross-chain transfer details
“Pull up the raw details for transaction 0x9988776655... on Polygon — I need the from/to addresses, value, nonce, and block number for my audit trail.”

Endpoint
GEThttps://chain.intel.rallylive.ca/chain/tx?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need raw, low-level transaction fields (from, to, value, nonce, gas, method selector, pending status) for a specific tx hash across Base, Ethereum, Arbitrum, Optimism, Polygon, or BSC. It is ideal for payment verification, transaction auditing, debugging contract calls, and checking mempool status. Prefer it over block-level endpoints when you have a specific tx hash rather than a block number, and over wallet portfolio endpoints when you need per-transaction detail rather than aggregate balances.
Side effects
- Transaction hash not found on the specified chain — returns 404 or empty result
- Invalid or malformed transaction hash format — returns validation error
- Unsupported chain prefix — returns error indicating unknown network
- Network or RPC node timeout — returns 5xx or timeout error
- Payment not processed (x402 protocol failure) — request blocked before execution
