# Global Weather Dew Point Calculator

> Global Weather Dew Point Calculator is a paid API for AI agents from weather-global.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-21).

Calculates dew point temperature from air temperature and relative humidity, returning values in both Celsius and Fahrenheit along with a human comfort class and condensation likelihood hint.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability global-weather-dew-point-calculator-2635f4b1
```

Example prompt: What's the dew point if the air temperature is 28°C and relative humidity is 75%? Also tell me whether condensation is likely and how comfortable it will feel.

## When to prefer this

Choose this endpoint when you need a fast, computed dew point from known temperature and relative humidity values — especially when you also want a human-readable comfort classification and condensation guidance in a single call. Prefer it over generic weather forecast endpoints when you already have the temperature and humidity values and don't need geolocation-based lookups.

## Known failure modes

- Missing required query params (temp or humidity) returns a validation error
- Humidity value outside 1–100 range may cause an error or unexpected result
- Invalid unit string (not C or F) may default to C or return an error
- Network or upstream service timeout returns a non-200 response
- Payment failure via x402 protocol prevents access to the endpoint

## How this service works

Dew point from air temperature and relative humidity in C and F, with a human comfort class and condensation hint.

## Output

Returns dew point in both Celsius and Fahrenheit, the temperature-dewpoint gap (gapC), a human comfort classification string (e.g. 'comfortable', 'muggy', 'oppressive'), a condensation verdict or hint, the formula used, a plain-language summary, and the original input values (temperatureC, temperatureF, humidityPct). May also include a disclaimer and degraded flag if data quality is reduced.
