## How to call it through Zero

```sh
zero fetch --capability rotary-agency-wikibooks-api-3880e20a
```

Example prompt: Can you pull up the Wikibooks content on introductory Python programming so I can use it as reference material?

## When to prefer this

Choose this endpoint when you need programmatic, pay-per-call access to Wikibooks content without managing your own Wikimedia API integration. Useful for agents that occasionally need educational reference data and prefer microtransaction pricing over subscription APIs.

- Invalid or missing query parameter — returns error response
- Wikibooks upstream unavailable — may return 502 or timeout
