## 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 api-direct-threads-user-lookup-by-username-14fdc84a
```

Example prompt: Can you look up the Threads profile for the username '@zuck' and tell me their bio, follower count, and any other account details you find?

## When to prefer this

Choose this endpoint when you need structured profile data for a single, known Threads username. It is purpose-built for direct handle-to-profile resolution and is more efficient than a keyword search when the exact username is already known. Prefer this over search endpoints when you want authoritative account metadata (follower count, bio, ID) rather than discovery of new accounts.

## Known failure modes

- Username not found – returns 404 or empty result if the handle does not exist on Threads
- Private or suspended account – profile data may be unavailable or partial
- Rate limiting – too many requests in a short window may return 429
- Invalid username format – usernames exceeding 100 characters or containing invalid characters may be rejected
- Network timeout – upstream Threads API may be slow or unavailable

## How this service works

Look up a single Threads user by username.

## Output

Returns structured public profile data for the requested Threads user, including user ID, display name, username, bio/description, follower count, following count, and other available account metadata fields.
