How this service works
Base transaction receipt API for AI agents — verify any Base txHash: status, block, gas, decoded USDC transfers. $0.001 USDC on Base per call. No key needed.
Output
Returns the transaction status (success/failed/pending), block number, gas used, and decoded USDC transfer details including sender address, recipient address, and transfer amount for the given Base transaction hash.
Example use cases
Confirm a USDC payment receipt
“I need to confirm that the USDC payment I sent on Base actually went through — the tx hash is 0xabc123...def456. Can you check if it succeeded and tell me the amount transferred and the recipient address?”
Audit gas costs for a transaction
“Can you pull up the receipt for Base transaction 0x9f8e7d...c4b3a2 and tell me exactly how much gas was used and what block it was included in?”
Verify pending transaction status
“I'm waiting on a Base chain transaction — hash 0x1234ab...5678cd — can you check whether it's confirmed, still pending, or failed?”
Technical details
Endpoint
POSThttps://api.mekongtradeintel.com/payment-receipt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify the outcome of a specific Base blockchain transaction by its hash, especially when you need decoded USDC transfer details alongside standard receipt data (status, block, gas). Prefer this over a generic block explorer when you need programmatic, structured output for an AI agent workflow and don't want to manage API keys.
Side effects
- Invalid or malformed txHash returns an error indicating the hash format is unrecognized
- Transaction not yet indexed returns a pending or not-found status
- Non-USDC transactions may return empty decoded transfer fields
- Payment of $0.001 USDC on Base required per call; unpaid requests return a 402 error
- Network congestion or RPC delays may cause slow or timeout responses
