Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 twitter-x-autocomplete-search-suggestions-c4c38d3b
```

Example prompt: What search suggestions does X give when someone starts typing 'climate chan' in the search bar?

## When to prefer this

Use this endpoint when you need to discover how X's own search engine would complete a partial search term — ideal for keyword research, hashtag discovery, brand monitoring query expansion, or building search-assisted UIs backed by real X suggestion data. Prefer this over a full search endpoint when you only have a partial query and want to enumerate plausible complete search terms before committing to a full search.

## Known failure modes

- Empty query string — returns validation error since query must be at least 1 character
- Query too long — rejected if exceeds 200 character limit
- X API rate limiting — upstream rate limits may cause temporary failures
- No suggestions found — partial query may return an empty suggestions list if X has no matches
- Network or upstream X API downtime — may return 5xx errors

## How this service works

Get X search suggestions for a partial query.

## Output

Returns a structured response containing X's autocomplete suggestions for the given partial query, including a list of suggested search completions and metadata such as the timestamp when the query was made. Results may include a cursor for pagination if more suggestions are available.
