x402
Apparent Temperature Calculator (Heat Index & Wind Chill) is a paid API for AI agents from units-convert.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-21).
Calculates apparent (feels-like) temperature using heat index from temperature and humidity, or wind chill from temperature and wind speed, with a danger category.

How this service works
Apparent temperature: heat index from temperature and humidity, wind chill from temperature and wind, with a danger category.
Output
Returns the feels-like temperature in Fahrenheit (feelsLikeF), the computed heat index (heatIndexF), a heat danger category (heatCategory), a human-readable summary, list of reasons, a verdict on safety, disclaimer, and metadata like source and timestamp. Also indicates if any metric was not checked or if the result is degraded.
Example use cases
Summer heat safety check
“It's 102°F today with 75% humidity — what's the heat index and what danger category does that put us in?”
Winter wind chill warning
“Temperature is 10°F and winds are blowing at 35 mph — how cold does that actually feel outside?”
Outdoor event planning alert
“We're planning an outdoor event where it's forecast to be 95°F with 90% humidity — what's the apparent temperature and should we be worried about heat danger?”
Technical details
Endpoint
GEThttps://units-convert.x402tookit.com/feels-like?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to compute apparent (feels-like) temperature from raw weather readings — especially when you need a danger category or human-readable safety verdict alongside the numeric result. Prefer this over general unit converters when the user's question involves comfort, safety, or physiological impact of weather conditions.
Side effects
- Missing required temp_f parameter returns an error
- Humidity or wind speed out of physical range may return degraded or null results
- Wind chill not calculated if wind_mph is not provided; heat index not calculated if humidity_pct is not provided
- Extreme edge-case values (e.g. negative humidity) may produce null outputs with degraded flag set to true
