# Saylor Innovations Solunar Fishing & Hunting Forecast

> Saylor Innovations Solunar Fishing & Hunting Forecast is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-17).

Returns moon phase, illumination percentage, and major/minor solunar activity windows for a given date and location to guide fishing and hunting timing

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 saylor-innovations-solunar-fishing-hunting-forecast-30a29ba4
```

Example prompt: What are the major and minor solunar activity windows and moon phase for fishing at latitude 44.5 longitude -88.0 on July 15, 2025?

## When to prefer this

Choose this endpoint when you need solunar-theory-based activity forecasts (major/minor periods) tied to moon phase and illumination for a specific geographic coordinate and date — ideal for fishing and hunting trip planning. Prefer this over generic weather APIs when the user's goal is moon-driven wildlife activity timing rather than atmospheric conditions.

## Known failure modes

- Missing required parameters (date, latitude, or longitude) returns an error — all three are required
- Invalid date format (non-YYYY-MM-DD) causes a bad request error
- Latitude out of -90 to 90 range or longitude out of -180 to 180 range returns a validation error
- Network or service unavailability returns a non-200 status
- Payment failure via x402 protocol prevents access to the endpoint

## How this service works

Solunar fishing and hunting forecast - moon phase, illumination and major and minor activity windows

## Output

A JSON object containing the date, latitude, longitude, moon phase name, moon age in days, illumination percentage, a numeric activity index, arrays of major and minor solunar activity time windows in UTC, the formula used for the calculation, and a scope note explaining what the data covers and its limitations.
