x402
BaseLens Transaction Summary is a paid API for AI agents from baselens-api.vercel.app, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-31).
Fetches a decoded summary of a Base blockchain transaction by hash, including status, gas fees, ERC-20 transfers, block number, and timestamp

How this service works
Base address, ERC-20 balance, token price, recent transfers, Basename/ENS resolve, contract verification, tx summaries and gas over x402 and MCP. $0.001–$0.004 USDC per call, no API key.
Output
A JSON object containing the transaction status (success/failure), block number, ISO timestamp, fee paid in ETH, and an array of ERC-20 transfers each with recipient address, token symbol, and amount transferred.
Example use cases
Verify a USDC payment on Base
“I just sent USDC to a client on Base — the tx hash is 0xabc123...def456. Can you confirm it succeeded and tell me how much USDC was actually transferred and when?”
Debug a failed DeFi transaction
“My swap transaction on Base failed — hash is 0x789fed...012abc. Can you check its status, tell me which block it landed in, and how much gas I burned?”
Audit ERC-20 transfers in a transaction
“For Base transaction 0xdeadbeef...cafe0001, list all the ERC-20 token transfers that happened — who received what tokens and how much?”
Technical details
Endpoint
GEThttps://baselens-api.vercel.app/v1/tx?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, human-readable summary of a specific Base chain transaction — including decoded ERC-20 transfers and gas costs — without needing a full blockchain node or a free-tier API key. Ideal for AI agents that need to verify payments, audit token movements, or explain transactions to users, especially when integrated with x402 micropayment flows on Base.
Side effects
- Invalid or malformed transaction hash returns an error
- Transaction hash from a non-Base chain (e.g. Ethereum mainnet) may not resolve
- Very recent transactions may not yet be indexed
- Network or RPC downtime causes lookup failure
- Payment (x402) fails if wallet has insufficient USDC
