## 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-reverse-image-search-serp-a9990108 -d '<json body>'
```

Example prompt: Can you do a reverse image search on this photo — https://example.com/mystery-photo.jpg — and tell me where it appears online and what it might be?

## When to prefer this

Choose this endpoint when you need to perform Google reverse image searches programmatically in a pay-per-use, no-subscription model using the x402 micropayment protocol. It is ideal for agents that only occasionally need reverse image lookups and want to avoid managing API keys or monthly subscriptions — paying $0.01 USDC per call instead. Prefer this over direct SerpApi or Google Vision integrations when your agent infrastructure already supports x402 payments.

## Known failure modes

- Invalid or inaccessible image URL returns empty or error results from upstream
- Payment failure via x402 protocol blocks the request before it reaches the upstream
- Upstream SERP provider rate limit or outage causes 5xx passthrough error
- Malformed query parameters result in no results or upstream 400 error
- Image URL blocked by upstream provider's content policy returns no results

## How this service works

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

## Output

Returns the upstream Google SERP reverse image search results, including matched pages, visually similar images, image source URLs, titles, and snippets — passed through directly from the upstream provider after successful x402 micropayment.
