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 2s-global-weather-forecast-fb89cb30
```

Example prompt: What's the 10-day weather forecast for London (51.5074, -0.1278) in imperial units — and can you break it down hour by hour?

## When to prefer this

Choose this endpoint when you need a global weather forecast for any arbitrary lat/lon coordinate with flexible horizon (up to 16 days), optionally at hourly granularity, and you want pay-per-call pricing with no API key setup. Prefer this over historical weather endpoints when you need future forecasts, and over city-name-based APIs when you have precise coordinates.

## Known failure modes

- Missing required lat/lon parameters → 400 Bad Request
- lat out of range (-90..90) or lon out of range (-180..180) → 400 validation error
- days parameter outside 1–16 range → validation error or clamped value
- Payment not provided or insufficient USDC → 402 Payment Required
- Upstream weather data provider outage → 503 or degraded response
- Invalid units value (not 'metric' or 'imperial') → 400 error

## How this service works

The (most) everything API: 575+ pay-per-call endpoints for AI agents — ground-truth data, a full AI gateway, and agent infrastructure (storage, queues, watchers). USDC via x402, no signup, no API keys, and upto billing: pay actual usage, not the quote.

## Output

A structured weather forecast for the given coordinates containing either daily summaries or hour-by-hour breakdowns over the requested number of days (1–16), including temperature, precipitation, wind speed, and other meteorological variables in the requested unit system (metric or imperial).
