Technical details
Endpoint
GEThttps://simple-x-api.com/api/2/users/by/username/rsproule?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve a specific X (Twitter) username to their full user profile object (including user ID) and are comfortable with micropayment-per-call via x402. Prefer this over scraping or unofficial APIs when you need reliable, structured X API v2 data without managing your own X API credentials.
Side effects
- Username not found — X API returns 404 or empty result
- Username suspended or deactivated — X API returns appropriate error
- Payment authorization failure — x402 payment up to $10.00 not authorized
- Rate limiting by X API — upstream throttling returns 429
- Network or proxy error from simple-x-api.com — upstream connectivity issue
