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 twit-sh-bookmark-tweet-a12415e2 -d '<json body>'
```

Example prompt: Bookmark tweet ID 1110302988 for me on X using my auth_token and ct0 cookie so I can find it later.

## When to prefer this

Use this endpoint when an AI agent needs to programmatically save a tweet to a user's X bookmarks using existing session credentials, without setting up Twitter's official API keys. Ideal for automation workflows that monitor tweets and save relevant ones, paying per-request in USDC.

## Known failure modes

- Invalid or expired auth_token/ct0 cookies result in authentication failure
- Missing required tweet ID returns a validation error
- Tweet ID does not exist or is inaccessible returns not found error
- Rate limiting by Twitter/X backend may cause request failures
- Payment failure (insufficient USDC) blocks the request before it reaches Twitter

## How this service works

Real-time Twitter/X data for AI agents. No sign-up, no API keys. Pay per request in USDC on Base via x402.

## Output

Returns a JSON object confirming the bookmark action, including the tweet ID and a boolean 'bookmarked: true' field indicating success.
