## 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-precip-ai-relative-humidity-451a97df
```

Example prompt: Can you get me the hourly relative humidity readings for the location at 37.7749° N, 122.4194° W for today? I need the full 24-hour breakdown as percentages.

## When to prefer this

Use this endpoint when you need hour-by-hour relative humidity data for a precise geographic location, especially for agricultural planning, HVAC optimization, weather monitoring, or any application requiring fine-grained atmospheric moisture data. Prefer this over daily summaries when temporal resolution within a day matters.

## Known failure modes

- Invalid or missing coordinates return a 400 error
- Location outside supported geographic coverage returns no data or error
- Invalid date range or future dates beyond forecast window return an error
- Authentication or payment failure returns a 402 or 401 error
- Rate limiting may return a 429 error for excessive requests

## How this service works
