## 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-google-lens-serp-via-x402-57041d05 -d '<json body>'
```

Example prompt: Can you run a Google Lens search on this image URL — https://example.com/shoe.jpg — to find similar products and where I can buy them?

## When to prefer this

Choose this endpoint when you need Google Lens-specific visual search results — such as product identification, reverse image search, or object recognition — and want to pay per-call via the x402 micropayment protocol without managing a SerpAPI subscription directly. Particularly useful for AI agents operating in web3/DeFi contexts where crypto micropayments are preferred.

## Known failure modes

- Invalid or inaccessible image URL returns an error from the upstream SERP provider
- Insufficient USDC balance or failed x402 payment results in a 402 Payment Required response
- Malformed query parameters cause a 400 Bad Request
- Upstream SERP provider rate limit or quota exhaustion returns a 429 or 503
- The path parameter may be incorrectly set, routing to a wrong upstream endpoint

## How this service works

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

## Output

Returns the upstream Google Lens SERP response, which typically includes visually similar images, product matches with prices and retailers, identified objects or entities, and any text extracted from the image.
