Technical details
Endpoint
POSThttps://kite-hub-v3.vercel.app/api/username-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-use username availability check without setting up a dedicated integration. Useful for agents that need to validate username options on demand, especially when cost predictability per call matters (flat $0.06 USDC). Prefer this over manual browser checks or platform-specific APIs when you want a single unified endpoint.
Side effects
- Username not provided — request returns an error indicating missing required field
- Platform not supported — endpoint may return an error or empty result
- Rate limiting — too many requests in a short window may result in throttling
- Network timeout — vercel deployment may occasionally be slow or unavailable
- Invalid characters in username — may return validation error
