$0.003 per call · failed calls are never charged · no account or API key needed

Returns up to 100 logs with block, transaction hash and topics. Use to watch transfers or contract events; for one transaction's outcome use polygon_receipt.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/polygon/logs?address=0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/polygon/logs?address=0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359&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, Monad, World Chain or Tempo) and retries.
