Subscribe for 30 days to a change feed of the x402 network, from our own probes (~2 per host per day, 1500+ hosts). Returns a handle and a cursor; polling is then free and unlimited: /x402/network-feed/since returns all that changed since your cursor (down/up, payTo drift, price drift, manifest gained/lost), and /x402/network-feed/check takes up to 50 hosts you are about to pay and returns their last observed status, payTo and price plus changes. Facts only, no scores and no catalogue data.

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".
