Base transaction status and details: check whether a Base transaction succeeded, its sender, value and fee

$0.003 per call · failed calls are never charged · no account or subscription: pay per call with a card key or USDC

Look up any transaction on Base by hash: whether it succeeded, reverted or is still pending, sender and receiver, ETH value, called method id, block number and time, number of confirmations, gas used, gas price and the execution fee paid, and whether it created a contract. Use to confirm that a payment or contract call went through before acting on it.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://tools.funwords.eu/base-tx?hash=0x7d108fa131ed949c76d50caf2e7dfe25fc9903b9d276c40a0446d8afbdfe86b0"

Or one of your 25 free calls, no key:

curl "https://tools.funwords.eu/base-tx?hash=0x7d108fa131ed949c76d50caf2e7dfe25fc9903b9d276c40a0446d8afbdfe86b0&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.
