Workers · WEB Places
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. Send a query, get back compact JSON: top places with position, title, address, coordinates, rating, rating count, category, phone and website. 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.
Workers · Preflight
mcpfax-reliability.bowling-anthony.workers.dev
Advisory preflight on one endpoint before a consequential call: a bounded live probe (reachable, status, latency, MCP initialize, current x402 price and payTo) joined to our observed history (reliability over a stated window, payTo and price changes, first seen). Returns ALLOW, WARN or UNKNOWN. Never a guarantee. No evidence, no charge.
Workers · Weather
mcpfax-utility.bowling-anthony.workers.dev
Weather forecast — Current conditions, the next 12 hours with rain probability, a multi-day forecast, and a plain answer to "will it rain".
