Endpoint
x402-seller.onrender.com/air/quality
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.
Score
The score is built from observations we collect ourselves: how the endpoint responds, what the envelope contains, how stable the price and the recipient are, who pays and how often. It is deterministic — the same input always produces the same result.
We do not publish the exact methodology yet. If you own this endpoint, write to us and we will show you, item by item, what drags the score down.

Is this your endpoint?
The score is built only from public observations. If something we recorded is wrong — say our prober hit you during maintenance — write to us. We will recheck and publish your reply next to the score.
We do not delete accurate observations. The prober makes at most one request per second per host and only asks for the payment challenge — it never pays and never takes content.
