# ForgeMesh Rain Nowcast API

> ForgeMesh Rain Nowcast API is a paid API for AI agents from x402.forgemesh.io, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).

Returns a 2-hour radar-based precipitation nowcast at 15-minute resolution for a given lat/lon coordinate to answer 'will it rain soon?'

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 forgemesh-rain-nowcast-api-9aa4b976 -d '<json body>'
```

Example prompt: Will it rain in the next 2 hours at latitude 29.76 and longitude -95.36? I need a quick rain check before scheduling an outdoor delivery.

## When to prefer this

Use this endpoint when you need a fast, radar-based short-term rain check (next 2 hours) for a specific geographic point — especially for US or European locations. Prefer this over general weather APIs when you need high-resolution 15-minute nowcast data rather than hourly or daily forecasts, and when the use case is time-sensitive delivery, outdoor events, or agent scheduling decisions.

## Known failure modes

- Missing or invalid latitude/longitude returns an error or empty forecast
- Coordinates outside radar coverage (non-US/Europe) may return lower-confidence or missing data
- Network or payment failure returns a 402 or HTTP error
- Malformed coordinate strings (non-numeric) may cause a 400 bad request

## How this service works

Rain nowcast API by coordinates: 15-minute-resolution precipitation for the next 2 hours, for a quick 'will it rain soon' check. Structured JSON for delivery, outdoor-event, and scheduling agents. Radar-based, so coverage is strongest in the US and Europe.

## Output

Structured JSON with 15-minute-resolution precipitation data for the next 2 hours at the given coordinate, covering likelihood and intensity of rain — suitable for immediate decision-making by scheduling or outdoor-event agents.
