# ReadX Broadcast Details

> ReadX Broadcast Details is a paid API for AI agents from readx.sh, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

## 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-broadcast-details-201bc295
```

Example prompt: Can you pull up the details for X broadcast ID 1234567890 — I want to know the title, whether it's still live, how many people are watching, and whether there's a replay link I can stream?

## When to prefer this

Use this endpoint when you need structured JSON metadata for a specific X/Twitter Space or broadcast — particularly when you need the replay m3u8 stream URL, live state, or watch count without building a Twitter API integration yourself. Prefer this over the official Twitter API when you want a simple pay-per-call model without OAuth setup.

## Known failure modes

- Invalid or non-numeric broadcast ID returns a 400 or 422 error
- Broadcast ID not found returns a 404 error
- Payment not provided or insufficient returns a 402 Payment Required error
- Broadcast exists but has no replay yet (still live or no recording) may return null for m3u8 field
- X/Twitter API rate limits or downtime may cause 429 or 503 responses

## How this service works

A Spaces / broadcast: title, state, watch count, replay m3u8. Example: GET /api/broadcasts/1

## Output

Returns a JSON object containing the broadcast's title, current state (e.g. live, ended), total watch count, and a replay m3u8 URL if the broadcast has concluded and a recording is available.
