## 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 quantaflow-bing-reverse-image-search-5dc2ab04 -d '<json body>'
```

Example prompt: Can you do a reverse image search on Bing for this photo — https://example.com/photo.jpg — and tell me where else this image appears online and what similar images come up?

## When to prefer this

Choose this endpoint when you need Bing-specific reverse image search results and are operating in a web3/x402 micropayment environment where per-call USDC billing is acceptable. Prefer this over Google reverse image alternatives when Bing's index coverage is sufficient, or when you need a pay-per-use model without API key management. The x402 protocol makes it suitable for autonomous AI agents that can authorize micropayments programmatically.

## Known failure modes

- Invalid or inaccessible image URL returns empty or error result from Bing
- Payment failure or insufficient USDC balance causes x402 payment rejection before request is forwarded
- Malformed query parameters result in upstream API error
- Rate limiting from underlying Bing Search API may cause transient failures
- Image URL behind authentication or firewall may not be indexable by Bing
- Cold-start latency on Vercel serverless may occasionally cause timeout

## How this service works

Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.

## Output

Returns the upstream Bing reverse image search response including visually similar images, pages that contain the image, related search queries, and image metadata such as dimensions and source URLs — passed through as-is from the Bing API after successful x402 micropayment.
