## 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 precip-ai-hyperlocal-weather-data-api-cloud-cover-hourly-626e7565
```

Example prompt: What's the hourly cloud cover fraction for latitude 39.7392, longitude -104.9903 over the next 24 hours — I need to know when the sky will be clearest?

## When to prefer this

Choose this endpoint when you need hyperlocal, site-specific hourly cloud cover data at a precise GPS coordinate — particularly useful for solar irradiance estimation, agricultural planning, drone operations, or any time-sensitive application requiring granular sky condition data at sub-regional resolution. Prefer this over general weather APIs when precision at a specific point matters more than broad regional forecasts.

## Known failure modes

- Invalid or missing latitude/longitude returns a 400 error
- Requested time range outside available historical or forecast window returns an error or empty result
- Location in an unsupported geographic region may return no data
- API authentication failure returns a 401 unauthorized error
- Rate limit exceeded returns a 429 error

## How this service works

Hourly cloud cover fraction (0-1, where 0 is clear and 1 is overcast)

## Output

An array of hourly records, each containing a timestamp and a cloud cover fraction value between 0 (completely clear) and 1 (fully overcast), for the requested location and time range.

## Example request

```json
{
 "hours": 24,
 "latitude": 39.7392,
 "longitude": -104.9903
