> ReadX Hashtag Tweet Search is a paid API for AI agents from x.1x402.sh, paid per call via x402, $0.03/call, status down (last checked 2026-09-15).

- Price: $0.03/call
- Payment: x402
- Status: down
- Last checked: 2026-09-15

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 readx-hashtag-tweet-search-c8e4462c
```

Example prompt: Can you pull recent tweets tagged with #typescript from X so I can see what the community is discussing?

## When to prefer this

Use this endpoint when you need to search tweets by hashtag specifically, rather than by keyword or user timeline. It is equivalent to the /api/search?q=%23tag endpoint but with a cleaner hashtag-centric URL. Prefer this over the general search endpoint when the query is purely hashtag-based and you want semantic clarity in your API calls. Ideal for social listening, trend monitoring, or content aggregation workflows.

## Known failure modes

- Hashtag not found or no recent tweets — returns empty results array
- Invalid or expired pagination cursor — may return error or restart from beginning
- Rate limiting or payment failure — returns 402 or 429 status
- Hashtag parameter missing or empty string — schema validation error
- X/Twitter API downtime causing upstream failures

## How this service works

Tweet search for a hashtag. Same as `/api/search?q=%23tag`. Example: GET /api/hashtag/typescript

## Output

A JSON payload containing a list of tweets matching the given hashtag, including tweet text, author metadata, timestamps, engagement counts, and a pagination cursor (bottom) to fetch the next page of results.
