# Geo Sun Position & Solar Data Lookup

> Geo Sun Position & Solar Data Lookup is a paid API for AI agents from workspace-x402-paywall.onrender.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-11).

Returns solar position and sun-related geographic data (sunrise, sunset, solar noon, etc.) for a given latitude and longitude coordinate pair.

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 geo-sun-position-solar-data-lookup-e5cdece6
```

Example prompt: What are the sunrise, sunset, and solar noon times today for coordinates 37.7749° N, 122.4194° W (San Francisco)?

## When to prefer this

Use this endpoint when you need lightweight, pay-per-call solar position or sun timing data for a specific coordinate without a subscription. Ideal for agents performing one-off geospatial solar queries, scheduling workflows around daylight, or enriching location data with astronomical context. Costs only $0.005 USDC per call via x402 micropayment, making it suitable for low-volume or on-demand lookups where subscribing to a full astronomical API is overkill.

## Known failure modes

- Missing required lat or lon parameters returns an error
- Invalid or out-of-range coordinate values (e.g. lat > 90) may return an error or unexpected results
- Payment not provided or rejected results in 402 Payment Required
- Server may be unavailable on Render free tier due to cold starts causing timeout
- Fields parameter with invalid field names may return empty or partial results

## How this service works

66 pay-per-call APIs: AI text/image generation ($0.01), Polymarket odds, crypto prices, DeFi yields, FX rates, weather, IP/geo, FBI wanted, SEC tickers, clinical trials, 250M academic papers, Stack Overflow, meme-coin launchpads (pump.fun, Clanker, Four.meme, SunPump), tokenized stocks, Solana top 100, and 40+ more. $0.005/call standard. USDC on Base and Solana via x402.

## Output

Returns a JSON object containing solar data for the specified coordinates, which may include sunrise time, sunset time, solar noon, civil/nautical/astronomical twilight times, day length, and sun azimuth/elevation angle, depending on which fields are requested.
