How this service works
Look up a Base transaction by hash (optional receipt) for $0.001 USDC via live JSON-RPC. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.
Output
Returns structured on-chain transaction data from Base via JSON-RPC, including transaction hash, block number, sender, recipient, value, gas price, gas limit, input data, and optionally the transaction receipt with gas used, status (success/fail), logs, and contract address if applicable.
Example use cases
Verify payment confirmation on Base
“I sent a USDC payment on Base — the tx hash is 0xabc123...def456. Can you check if it was confirmed and show me the block number and status?”
Debug a failed Base transaction
“This transaction on Base failed: 0x9f8e7d...c3b2a1 — can you pull it with the receipt so I can see the gas used, the revert reason, and who sent it?”
Audit sender and value of a Base tx
“For the Base transaction 0x1234ab...5678cd, can you tell me who sent it, who received it, and how much ETH or token value was transferred?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/base-txWhen to prefer
Choose this endpoint when you need to look up a specific Base (Coinbase L2) transaction by hash and want structured on-chain data returned without managing your own RPC node or API keys. It is ideal for agents that need to verify payment confirmations, audit transaction details, or inspect receipts on Base, especially in x402-compatible micropayment workflows where per-call billing ($0.001 USDC) is preferred over subscriptions.
Side effects
- Transaction hash not found — returns null or error if the hash does not exist on Base
- Invalid hash format — malformed hash causes a JSON-RPC parse error
- Network or RPC timeout — live JSON-RPC call may fail if the Base node is unreachable
- Transaction pending — receipt unavailable if the transaction has not yet been mined
- Payment failure — call not executed if x402 USDC micropayment of $0.001 is not accepted
