## 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 image-search-api-multi-engine-x402-81e41661
```

Example prompt: Search for up to 10 images of the Northern Lights over mountains and give me the direct image URLs and their source pages.

## When to prefer this

Use this endpoint when an AI agent needs real image URLs (not generated images) for visual grounding, content enrichment, multimodal research, or fact-checking. Prefer it over web search endpoints when the primary need is image assets rather than text snippets. No API key or account required — just pay per query in USDC via x402, making it ideal for agent pipelines that need frictionless image lookup.

## Known failure modes

- Missing required query parameter 'q' → 400 Bad Request
- Payment not provided or insufficient USDC → 402 Payment Required
- Limit out of range (below 1 or above 20) → 400 validation error
- No results found for the query → empty results array
- Upstream image search engine unavailable → 502 or 503 error
