## 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 mesh-heurist-xyz-69ca68e1 -d '<json body>'
```

Example prompt: Can you pull the most recent tweets from @VitalikButerin's Twitter timeline so I can see what he's been announcing lately?

## When to prefer this

Use this endpoint when you need to retrieve the recent tweet history of a specific Twitter/X user, especially in Web3/crypto contexts. Prefer this over generic web scraping when you want structured social content from a known handle, or when you need to track announcements from a project or influencer on X.

## Known failure modes

- Invalid or non-existent Twitter username returns an error or empty result
- Rate limiting or access restrictions on the underlying Twitter/X API
- Private or suspended accounts may return no data
- Payment failure or insufficient USDC balance prevents the call from completing
- Network timeout from the Heurist Mesh infrastructure

## How this service works

Fetch a Twitter/X user's recent posts. Use when you want their latest activity or official announcements.

## Output
