Canadian Fire Weather Index Calculator
x402
Canadian Fire Weather Index Calculator is a paid API for AI agents from natur.halowerk.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).
Computes all components of the Canadian Fire Weather Index system (FFMC, DMC, DC, ISI, BUI, FWI) from an hourly forecast to quantify wildfire ignition and spread risk.

How this service works
Calculates the Canadian Fire Weather Index components from an hourly forecast: the Fine Fuel Moisture Code for the surface litter that carries ignition, the Duff Moisture Code and Drought Code for the deeper layers that determine whether a fire keeps going, the Initial Spread Index combining wind with surface dryness, the Buildup Index, and the resulting Fire Weather Index.
Output
Returns all six Canadian Fire Weather Index components: FFMC (surface litter flammability, 0–101), DMC (duff moisture, unitless), DC (drought severity, 0–1000), ISI (fire spread potential combining wind and FFMC), BUI (total fuel availability combining DMC and DC), and FWI (overall fire intensity/danger rating). Values are numeric and decision-ready for fire management planning.
Example use cases
Pre-burn fire danger assessment
“I have tomorrow's hourly forecast for our forest unit: temps peaking at 32°C, humidity dropping to 18%, winds at 40 km/h, zero rain expected. Can you run the full Canadian FWI system and tell me the Fine Fuel Moisture Code, ISI, and final Fire Weather Index so we can decide whether to proceed with the prescribed burn?”
Wildfire spread risk monitoring
“Run the Canadian Fire Weather Index calculation for today's forecast in this high-risk boreal region — the hourly data shows temps around 26°C, 25% RH, 20 km/h winds, and no precipitation over the past 24 hours. I need the Buildup Index and FWI especially to assess how far a fire could spread.”
Seasonal drought and fire danger tracking
“It's been a very dry summer and I want to track how deep the moisture deficit is getting. Feed this week's hourly forecast through the FWI system and give me the Drought Code and Duff Moisture Code so I know whether the deeper fuel layers are becoming a sustained fire risk.”

Endpoint
POSThttps://natur.halowerk.com/v1/fire-weatherWhen to prefer
Choose this endpoint when you need the full suite of Canadian Fire Weather Index components derived from hourly forecast data, especially when fire management decisions require all six indices (FFMC, DMC, DC, ISI, BUI, FWI) in a single call. Prefer it over manual computation or climatological lookups when real-time or forecast-driven fire danger assessment is needed. It is particularly suited for automated fire monitoring pipelines, prescribed burn go/no-go decisions, and seasonal fire risk tracking in boreal and temperate forest ecosystems.
Side effects
- Missing or malformed hourly forecast fields (temperature, RH, wind, precipitation) return a 400 validation error
- Out-of-range meteorological values may produce physically unrealistic FWI outputs
- Insufficient hourly resolution in forecast data may degrade index accuracy
- Payment failure via x402 protocol returns 402 with no computation performed
