## 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 twitter-x-user-extended-about-97bdc5c6
```

Example prompt: Can you pull the extended About information for the X account @OpenAI so I can see their full profile bio and account details?

## When to prefer this

Use this endpoint when you need the extended About / biography section of a public X user profile and have their username. Prefer this over general Twitter search endpoints when you already know the specific account and want structured profile metadata rather than tweets. It complements timeline or media endpoints when building a full picture of a user.

## Known failure modes

- Username not found or account suspended — returns empty or error data
- Invalid username format (exceeds 15 chars or contains illegal characters) — schema validation failure
- Private/protected account — no extended data returned
- Rate limiting by the underlying X API — request may fail or return partial data
- Network timeout to x402atlas.com proxy — connection error

## How this service works

Get the extended About information for a public X user.

## Output

Returns a JSON object with a `data` field containing the extended About details for the requested X user (bio, profile fields, and any other public about information), along with a `queried_at` ISO datetime stamp and an optional `cursor` for paginated results when provided by X.
