How this service works

One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.

Output

Returns the decoded event logs for the specified transaction, including raw log data alongside human-readable decoded fields for known event types such as ERC-20/ERC-721 transfers and approvals, DEX swap events, and contract admin events (e.g. ownership transfers, upgrades).

Example use cases

Trace a DeFi swap's events

“I have this Base transaction hash — 0x1a2b3c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0b1c2d3e4f5a6b7c8d9e0f1a2b — can you decode the event logs and show me what swaps and token transfers happened?”

Audit admin events on Ethereum

“Check the event logs for this Ethereum tx 0xabcdef1234567890abcdef1234567890abcdef1234567890abcdef1234567890ab and highlight any admin or ownership-change events that were emitted.”

Verify ERC-20 transfer in a transaction

“Did this transaction on Base — 0xdeadbeefcafebabe1234567890abcdef1234567890abcdef1234567890abcdef12 — actually emit a token transfer event? Show me the decoded logs so I can confirm the recipient and amount.”

Technical details

Endpoint

POSThttps://tanod.dev/v1/chain/logs?utm_source=zero.xyz

When to prefer

Use this endpoint when you need to inspect or decode the event logs of a specific on-chain transaction on Ethereum or Base — especially when you want human-readable decoding of token transfers, DEX swaps, or admin events rather than raw hex. Prefer this over generic RPC calls when decoded, structured output is needed without running your own ABI decoding logic.

Side effects

Invalid transaction hash format returns a validation error
Transaction not found on the specified chain returns a not-found error
Chain value outside 'ethereum' or 'base' is rejected
Transaction with no logs returns an empty log array
Network or node timeout may return a transient error
Unrecognized event signatures are returned as raw/undecoded log entries
