Event Log Decoding

blockchain

Serving

Decode the event logs of an Ethereum transaction: ERC-20 Transfer events come back typed (from, to, raw value, contract); every other log is returned raw with its topics and data. Values are in base units. POST /v1/log with {tx_hash}. Pay per request in USDC; no account, no API key.

Endpoint: POST https://agent.pocket.network/v1/event-log-decoding/v1/log
Price per call: $0.005 USD
Networks payable on: Base (eip155:8453), Tempo (eip155:4217)
Protocol: rest

Calling it
