GET /air/quality

unprobed

Current U.S. EPA Air Quality Index (AQI) and pollution levels for a specific location, given latitude/longitude — use to check smog, air pollution, or whether it's safe to be outside. Sourced from the EPA AirNow program (federal/state/local/tribal agencies); covers the US, Canada, and Mexico only. Data is preliminary and unvalidated per EPA data use guidelines — not for regulatory use.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

Try it (unpaid: shows the 402)

curl -si -X GET 'https://x402-seller.onrender.com/air/quality' -H 'accept: application/json'

The catalog declares GET. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
