## 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 x-twitter-user-profile-lookup-bfd83445 -d '<json body>'
```

Example prompt: Can you look up the public Twitter profile for the username 'OpenAI' and tell me their follower count, bio, and when the account was created?

## When to prefer this

Choose this endpoint when you need to resolve a known Twitter/X username to structured profile metadata — especially follower counts, bios, and account details — without needing to search for users or fetch their tweets. Prefer this over the tweet-search sibling endpoint when the username is already known and the goal is profile enrichment rather than content retrieval.

## Known failure modes

- Username not found — account does not exist or has been suspended
- Username is private or deactivated — limited or no profile data returned
- Rate limit exceeded from underlying X API v2
- Invalid username format passed in request body
- Payment failure via x402 protocol resulting in 402 response

## How this service works

## Output

Returns structured public profile data for the requested X/Twitter username including user ID, display name, bio/description, follower count, following count, tweet count, profile image URL, account creation date, and verification status.
