agentdata-api.sander-van-aard.workers.dev

Google Places (local businesses with rating, address and phone number) for AI agents at $0.004 per call, from the same Serper.dev source as /web/search.

Tune with num (1-10 results), country and language (2-letter codes). Zero results is a valid, honest answer. Pay per call in USDC on Base, no account, no API key.
