Avalanche recent event logs

$0.01 per call · failed calls are never charged · no account or API key needed

Recent contract event logs on Avalanche (eth_getLogs): the events a contract emitted over the last N blocks (1-1,000, default 50), optionally filtered by topic0 (the 0x 32-byte event signature hash). Returns up to 100 logs with block, transaction hash and topics. Use to watch transfers or contract events; for one transaction's outcome use avax_receipt.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/avax/logs?address=0xB97EF9Ef8734C71904D8002F8b6Bc66Dd9c48a6E"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/avax/logs?address=0xB97EF9Ef8734C71904D8002F8b6Bc66Dd9c48a6E&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.
