TruthBear Wildfire Region Gauge
x402
TruthBear Wildfire Region Gauge is a paid API for AI agents from api.truthbear.co, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-15).
Returns a 3-leg sequential wildfire risk chain for a US/Canada fire region: leading fire weather conditions → active NASA FIRMS satellite fire detections → EPA downwind smoke impact confirmation.

How this service works
[3-LEG] Wildfire chain, one fire-risk region (?entity=us-california): leading fire weather - hot, dry and windy -> current active fire detections from NASA FIRMS satellite thermal anomalies -> realized downwind smoke impact (confirmation gate). A chain, not one reading: confidence = how many legs are lit, in order. Sources: NASA FIRMS, NWS, EPA. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. $0.25 per call.
Output
A JSON object describing the three sequential wildfire chain legs: (1) fire weather conditions (hot, dry, windy from NWS), (2) active fire detections from NASA FIRMS satellite thermal anomalies, and (3) realized downwind smoke impact from EPA data. Confidence reflects how many legs are consecutively lit (0–3). If no data is available, returns HTTP 422 with no_charge and the call is not billed.
Example use cases
Emergency manager wildfire situation check
“Give me the full wildfire chain status for us-california right now — I need to know if we have dangerous fire weather, any active satellite detections, and confirmed smoke impact downwind, and how confident the chain is.”
Pacific Northwest smoke air quality alert
“Is there active wildfire smoke impacting the Pacific Northwest today? Check fire weather, NASA satellite fire detections, and smoke confirmation for us-pacific-northwest.”
Canadian wildfire season monitoring
“What's the current wildfire risk reading for British Columbia? I want to see all three legs — fire weather, active fire detections, and realized smoke impact — and how many are currently triggered.”
Technical details
Endpoint
GEThttps://api.truthbear.co/gauge/wildfire-regionWhen to prefer
Choose this endpoint when you need a multi-signal, sequentially-gated wildfire risk assessment for a specific US or Canadian fire region in a single call, combining fire weather, satellite fire detections, and smoke impact into one confidence-scored chain. Prefer this over raw satellite or weather APIs when you want cross-source confirmation rather than a single data point, and when you need descriptive current-state information (not a forecast or advisory).
Side effects
- 422 no_charge: no data available for the requested entity at call time — not billed
- Invalid entity ID returns an error; valid entity IDs can be retrieved from GET /gauge/catalog?signal_id=<signal_id>
- Network or upstream source (NASA FIRMS, NWS, EPA) outage may result in partial or no data
- Requesting a region not in the supported entity list (12 total) returns an error
