Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 simple-x-api-users-lookup-get-2-users-84436509
```

Example prompt: Look up the X (Twitter) user profile for the account with user ID 12345678 and get me their display name, bio, and follower count.

## When to prefer this

Use this endpoint when you need to fetch X (Twitter) user profile data programmatically without managing your own X API credentials or OAuth flow, and are willing to pay per-call via x402/USDC. Preferred for agents that need on-demand user lookups without rate-limit management overhead.

## Known failure modes

- User ID not found — X API returns 404 or empty data
- Invalid query parameters — returns 400 bad request
- X API rate limit exceeded — returns 429 too many requests
- Payment failure — x402 authorization up to $10 not satisfied
- User account suspended or deactivated — no data returned
- Proxy service unavailable — connection timeout or 503

## How this service works

Proxy the corresponding X API v2 endpoint. x402 authorizes up to $10.00; successful responses settle at X's public non-owned per-resource/per-action price.

## Output

Returns a user object from the X API v2 containing fields such as id, name, username, description, public_metrics (followers, following, tweet counts), profile image URL, verified status, and other profile metadata as supported by the X API v2 users endpoint.
