## 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 stablesocial-google-ad-library-advertiser-search-2911b1d0 -d '<json body>'
```

Example prompt: Search the Google Ad Library for advertisers promoting 'electric vehicles' in Germany and show me who's running ads.

## When to prefer this

Choose this endpoint when you need pay-per-request, no-subscription access to Google Ad Library advertiser search data, especially for competitive ad intelligence, brand discovery, or verifying who is advertising a specific keyword in a given country. Prefer this over scraping or official Google Ad Library UI when you need programmatic, agent-callable access without managing OAuth or API keys.

## Known failure modes

- Empty results if no advertisers match the query or region combination
- Invalid or unsupported country code returns an error or defaults to US
- Malformed query string may return no results or an API error
- Payment failure (402) if USDC balance is insufficient
- Rate limiting or timeout if the upstream Google Ad Library is slow to respond

## How this service works

Pay-per-request access to social media data from TikTok, Instagram, Facebook, Reddit, and LinkedIn. No auth, no subscriptions.

## Output

Returns a list of advertiser records matching the query from Google's Ad Library, including advertiser names and associated metadata for the given region.
