## 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 spyfu--d3e58d6e
```

Example prompt: Pull SpyFu PPC keyword data for 'project management software' — I want to see the cost per click, monthly search volume, and how many advertisers are competing for that term.

## When to prefer this

Use this endpoint when you need detailed PPC-specific keyword metrics — especially CPC estimates, advertiser competition counts, and ad history — sourced from SpyFu's extensive 18+ year database. Prefer this over generic keyword tools when you need competitor ad intelligence or historical paid search data rather than purely organic SEO signals.

- Keyword not found in SpyFu database returns empty results or 404
- Rate limit exceeded returns 429 with retry-after header
- Authentication or payment failure returns 402 or 401
