## 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`):

Example prompt: Can you do a Bing reverse image search on this photo — https://example.com/photo.jpg — and tell me where it appears online, including titles, source sites, and dates?

## When to prefer this

Choose this endpoint when you specifically need Bing's reverse image search index, which may surface different results than Google or Yandex. It is pay-per-call with no API key or subscription required, making it ideal for low-volume or ad-hoc lookups. Prefer this over Google reverse image when you want Bing's perspective, or when you need to cross-reference results across multiple search engines. The crop parameters (cal, car, cat, cab) make it especially useful when only part of an image is relevant to the search.

## Known failure modes

- Image URL is inaccessible or returns a non-image content type — search fails with an error
- Image dimensions exceed 4000x4000 pixels — rejected by the API
- Invalid or expired next_page_token causes pagination failure
- No results found for rare or very low-quality images
- Invalid mkt locale code causes malformed results or error
- Network timeout on the upstream Bing request
