## 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 api-rate-limit-documentation-search-for-integration-developers-111ee8ba -d '<json body>'
```

Example prompt: Search for the official rate limits and quota documentation for the Twilio SMS API — I need to know the per-second request caps and any retry-after guidance before we build our integration. Return the top 5 results.

## When to prefer this

Choose this endpoint when an agent or developer needs to quickly surface official or authoritative rate-limit and quota documentation for a specific third-party API provider before or during integration work. It is preferable to manual web browsing when automating integration research workflows, or when building tooling that needs to fetch throttling specs programmatically. Less suited for private or internal API documentation not indexed on the public web.

## Known failure modes

- No results found if the provider has no publicly indexed rate-limit documentation
- Generic or low-relevance results if the query is too vague
- Search may return community posts instead of official docs if official pages are poorly indexed
- max_results out of range (below 1 or above 10) causes validation error
- Network or upstream search service unavailability returns a 5xx error
