https://api.zfinia.com/x402/v1/base-transaction-outcome

Shares a payout wallet with 178 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Did my Base transaction work and what did it cost? One call returns success or reverted, gas used, effective gas price, the fee in wei and in exact decimal ETH, confirmations behind the head, sender, recipient, value and log count. Pending and unknown hashes get a definite answer rather than an error.

This payout wallet is shared: figures cover all 179 endpoints paid at it, since payments cannot be attributed to one of them. Only payments settled on chains and facilitators we index.

Linked by wallet — likely same operator

On-chain agent identity and the x402 endpoint that shares its settlement wallet.
