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 socialfetch-x-hashtag-search-6c31d683
```

Example prompt: Pull the latest 20 posts from the #AI hashtag on X, using the 'latest' section so I get the most recent ones first.

## When to prefer this

Use this endpoint when you need to search X posts by a specific hashtag (e.g. #Bitcoin) rather than free-text keywords — for free-text keyword search, use the sibling twitter.search.list endpoint instead. Prefer this when you need section-specific feeds (top, latest, photos, videos, people) or paginated hashtag results.

## Known failure modes

- Missing required 'hashtag' parameter returns a validation error
- Hashtag exceeding 256 characters is rejected
- Invalid 'section' enum value causes a bad request error
- Expired or invalid pagination cursor returns an error or empty results
- Rate limiting or downstream X API unavailability returns a 5xx error
- Requesting a limit above 20 is silently capped or rejected

## How this service works

Search X posts by hashtag (not free-text keyword — use twitter.search.list for that).

## Output

A list of X (Twitter) posts matching the given hashtag, filtered by optional section (top, latest, people, photos, videos), with a pagination cursor for fetching subsequent pages and up to 20 results per call.
