## 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 google-ad-library-search-727c49bc -d '<json body>'
```

Example prompt: Search the Google Ad Library for all active ads from Nike running in the United States and show me their ad creatives and any spend information available.

## When to prefer this

Use this endpoint when you need to programmatically query Google's Ad Library for advertiser transparency data, competitive ad research, or compliance auditing, without building your own scraper or managing Google API credentials. Prefer this over direct Google Ad Library access when you need pay-per-use pricing via USDC and no subscription overhead.

## Known failure modes

- Advertiser not found in Google Ad Library — returns empty result set
- Invalid or unsupported region code — may return error or empty results
- Rate limiting or upstream Google Ad Library unavailability — returns 5xx or timeout
- Malformed input query — returns validation error
- No ads matching the search criteria — returns empty data object
