## How to call it through Zero

```sh
zero fetch --capability openwebninja-reverse-image-search-fe0afaef
```

Example prompt: Can you do a reverse image search on this photo — https://example.com/photo.jpg — and find up to 50 pages across the web that use or reference it? Show me titles, domains, and any product prices if it appears in e-commerce listings.

## When to prefer this

Use this endpoint when you need to find web pages that use or reference a specific image identified by its URL, especially for verifying image originality, tracking image reuse, finding product listings associated with an image, or discovering the source of an unknown image. Prefer this over text-based image search when you already have a direct image URL and want provenance or duplication data.

## Known failure modes

- Invalid or inaccessible image URL returns an error or empty results
- URL parameter missing causes a 400-level validation error
- Image not indexed by Google yields an empty data array
- limit value out of range (below 1 or above 500) causes a schema validation error
- Payment not completed results in a 402 response and no data returned
- safe_search enum value not matching 'off' or 'blur' causes a validation error
