## 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 superhighway-image-search-b3b4d4f9
```

Example prompt: Search the live web for images of the Northern Lights and give me up to 10 results.

## When to prefer this

Use this endpoint when you need live web image search results from the current internet, especially when freshness matters and you want to pay per call without a subscription. Prefer this over general web search endpoints when the task is specifically image retrieval.

## Known failure modes

- Missing required query parameter 'q' returns a validation error
- Limit exceeds maximum of 20 — clamped or rejected
- No results found for obscure or overly specific queries
- Payment failure (402) if no USDC balance available
- Rate limiting if too many calls in a short period
