# fittings Solar Sun Position

> fittings Solar Sun Position is a paid API for AI agents from fittings.sh, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-11).

Returns the sun's azimuth, elevation, shadow ratio, and normal-facing panel angles for a geographic coordinate at a specific instant.

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 fittings-solar-sun-position-870dcc98
```

Example prompt: What's the sun's azimuth, elevation, and shadow ratio right now at latitude 37.7749, longitude -122.4194 (San Francisco)?

## When to prefer this

Choose this endpoint when you need precise, computed solar geometry data — azimuth, elevation, shadow ratio, and panel normal angles — for a specific coordinate and moment. It is ideal for solar energy planning, architectural shading studies, agricultural timing, photography, and real-time sun tracking. Prefer it over weather APIs that only give daylight hours, and over astronomy APIs focused on planetary data rather than solar geometry.

## Known failure modes

- Missing required lat or lon parameters returns a 400 error
- Latitude out of range (-90 to 90) or longitude out of range (-180 to 180) returns a validation error
- Invalid ISO 8601 format for the 'at' parameter returns a parse error
- Network timeout or service unavailability returns a 5xx error
- Payment failure due to insufficient USDC balance blocks the request

## How this service works

The sun's azimuth, elevation, shadow ratio and normal-facing panel angles at a coordinate and instant.

## Output

Returns the sun's azimuth (compass bearing in degrees), elevation (angle above horizon in degrees), shadow ratio (shadow length relative to object height), and the normal-facing panel angle (optimal tilt for a panel to face the sun directly) for the given latitude, longitude, and instant.
