## 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-list-search-279de9ec
```

Example prompt: Search X for public lists about 'machine learning researchers' and show me what comes up.

## When to prefer this

Use this endpoint when you need to discover or enumerate public X (Twitter) lists by topic or keyword, rather than searching for individual posts or users. It is ideal for community research, influencer mapping, or building feeds around curated X lists. Prefer this over the general tweet search endpoint when the goal is list discovery rather than individual post retrieval.

## Known failure modes

- Empty result set if no lists match the query (result_count: 0)
- Query string too long (exceeds 200 characters) returns a validation error
- Missing required query parameter returns a 400 bad request
- X API rate limits or downtime may cause 429 or 5xx errors
- Cursor for pagination may be absent if there is only one page of results

## How this service works

Search public X lists by query.

## Output

Returns an array of matching public X list objects (with metadata such as list name, description, owner, and member count), a total result count, the timestamp the query was executed, and an optional opaque cursor for pagination when more results are available.
