## 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 citable-run-serp-414b57bc
```

Example prompt: Search Google for 'best project management software for remote teams' and give me the organic results, People Also Ask questions, and related searches — use US results in English, show me 20 results.

## When to prefer this

Use this endpoint when you need raw, structured Google SERP data — including organic results, PAA boxes, and related searches — without standing up your own scraping infrastructure. Prefer it over general web-scraping tools when you specifically need Google results in a clean structured format, or over SEO platform APIs when you need live, real-time SERP snapshots rather than historical keyword databases. Well-suited for content strategy research, competitor monitoring, and feeding downstream SEO analysis pipelines.

## Known failure modes

- Missing required 'keyword' parameter returns a validation error
- Keyword exceeding 120 characters is rejected
- Invalid country code (gl) or language code (hl) may return unexpected results or an error
- num parameter outside 10–50 range may be rejected or clamped
- Payment failure (insufficient USDC balance) blocks the request
- Google rate-limiting or blocking may cause upstream failures
- Empty result sets returned for very obscure or misspelled queries
