Technical details
Endpoint
POSThttps://sna4an-sosmed-v1.vercel.app/api/x-checker?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, low-cost ($0.16 USDC) check on an X/Twitter username or account status without setting up your own Twitter API credentials. It is well-suited for brand research, influencer verification, or username availability checks at scale via micropayment-gated access.
Side effects
- Query string missing or empty — endpoint may return an error or empty result
- Username does not exist on X — may return not-found status
- Rate limiting or payment failure — 402 response if micropayment not processed
- Ambiguous query string — unclear if searching by handle or display name
- X platform API changes may cause stale or inaccurate results
