## 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-4b86273f -d '<json body>'
```

Example prompt: Can you fetch the last 10 tweets from @ethereum's Twitter account so I can see their most recent announcements?

## When to prefer this

Use this endpoint when you need to retrieve a specific Twitter/X user's recent timeline posts, especially for crypto projects, founders, or public figures. Prefer this over a general web search when you need structured, recent tweet data directly from a user's feed rather than aggregated mentions or trending signals.

## Known failure modes

- Invalid or non-existent Twitter handle returns an error or empty result
- User account is private or suspended — data unavailable
- Missing required 'identifier' field returns a validation error
- Payment failure (insufficient USDC) blocks the request
- Rate limiting or upstream Twitter API issues cause timeouts
- Malformed cursor value causes pagination errors
