How this service works
12 pay-per-call HTTP APIs settled in USDC on Base via x402 v2. No API keys, no accounts, no signup — $0.0005–$0.0020 per call. Includes a locally hosted 27B LLM endpoint.
Output
Returns a JSON object with the transaction's recipient address (to), sender address (from), transaction hash, value transferred (in ETH/USDC units), and confirmation status (1 = success, 0 = failed) for the queried Base chain transaction.
Example use cases
Verify incoming USDC payment
“Check if transaction 0xdeadbeef... on Base went through and who sent it — I'm expecting a USDC payment from a client and want to confirm it arrived.”
Audit agent payment trail
“Pull up the details for Base tx hash 0x1234abcd... — I need to see the from address, to address, value transferred, and whether it confirmed.”
Investigate failed transfer
“Look up transaction 0xfailed99... on Base and tell me its status — I think a payment I sent earlier didn't go through and I need to verify.”
Technical details
Endpoint
GEThttps://sableforge.servehttp.com/api/tx?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to look up a specific transaction on the Base blockchain by its hash and retrieve structured details (sender, receiver, value, status) without needing a full blockchain explorer or API key. Ideal for agents that need lightweight, pay-per-call on-chain transaction verification settled in USDC via x402.
Side effects
- Transaction hash not found — returns error if hash does not exist on Base
- Invalid hash format — malformed or non-hex hash string causes bad request
- Transaction still pending — unconfirmed transactions may not yet be indexable
- Payment failure — x402 USDC micropayment required; insufficient balance causes 402 response
- Network timeout — self-hosted node may be temporarily unavailable
