## 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 openwebninja-local-rank-tracker-grid-d18e83ca
```

Example prompt: Can you run a local rank tracker grid for my business (place ID 'ChIJN1t_tDeuEmsRUsoyG83frY3') searching 'coffee shop' centered at 37.341759, -121.938314, using a 5x5 grid with a 2 km radius, square shape?

## When to prefer this

Use this endpoint when you need geographically distributed local SEO rank data for a specific business across a grid of points rather than a single location check. Ideal for local SEO audits, competitive analysis, and understanding geographic visibility coverage for a Google Maps listing.

## Known failure modes

- Missing required parameters (place_id, query, lat, lng, grid_size, radius) returns a 400 error
- Invalid place_id returns empty or zero results
- Payment not provided or insufficient returns 402 Payment Required
- Grid size outside allowed enum values (3,5,7,9,11,13,15) returns validation error
- Coordinates outside valid geographic range may return no results
