AIMarket Nearby Sensors
x402
AIMarket Nearby Sensors is a paid API for AI agents from modelmarket.dev, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-12).
Returns the nearest live public sensor readings for a given location across specified layers (weather, air quality, radiation, seismic, etc.) with distance, source, and a signed receipt.

How this service works
The nearest live public sensors to a point, one per layer asked for (weather, air, radiation, quake …), each with its reading, distance and source, and a signed receipt.
Output
Returns one sensor entry per requested layer, each containing the sensor's current reading value and units, distance from the requested point, the data source name, and a cryptographically signed receipt attesting to the response authenticity.
Example use cases
Real-time air quality near office
“What's the air quality like right now near our office at latitude 51.5074, longitude -0.1278? Pull from the air and weather layers, and keep it within 30 km.”
Radiation check after news event
“I just heard about an incident near 35.6762° N, 139.6503° E — can you find the nearest live radiation sensor within 100 km and tell me what it's reading right now?”
Environmental data for field report
“I'm preparing a site assessment at coordinates 48.8566, 2.3522 — can you pull the closest public sensors for weather and air quality within 20 km, including their distance and source, with a signed receipt I can attach to the report?”
Technical details
Endpoint
POSThttps://modelmarket.dev/x402/nearby-sensors?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need geospatially-nearest live sensor readings across multiple environmental layers (weather, air, radiation, seismic) in a single call with verified provenance via a signed receipt. It is preferable to individual weather or air quality endpoints when you need multi-layer data or sensor attribution, and when verifiable receipts are required for audit or reporting purposes.
Side effects
- No sensor found within max_km for a requested layer — returns empty or error for that layer
- Invalid latitude/longitude outside valid ranges (-90..90, -180..180) — validation error
- Unknown or unsupported layer name — may be ignored or return an error
- max_km set too restrictively resulting in no sensors found
- Network timeout if upstream sensor data sources are slow
- Payment failure via x402 protocol before data is returned
