How this service works
Check username availability across 20+ social platforms and developer sites simultaneously — returns which platforms have a profile registered under that handle so agents can find people, verify identities, scout brand handles, or check name availability before registration.
Output
Returns a JSON object with a letter grade (e.g. 'A'), a numeric score (0-100), a per-platform results array listing each platform name, profile URL, and status (taken/available/unknown), plus aggregate counts for taken, available, and unknown platforms, and a findings array for notable observations.
Example use cases
Example prompt
“Can you check the username 'johndoe' across all the major platforms and tell me where it's taken, where it's available, and give me an overall availability grade?”
Technical details
Endpoint
GEThttps://netintel.dev/username-check/lookupWhen to prefer
Use this endpoint when you need a multi-platform username availability sweep in a single call with a scored summary. Prefer it over manual per-platform checks when building onboarding flows, brand registration workflows, or identity intelligence pipelines where a grade and aggregate count are needed alongside per-platform detail.
Side effects
- Username missing or empty — 400 bad request
- Username exceeds 50 characters or contains invalid characters — validation error
- Payment not provided or insufficient — 402 Payment Required
- Rate limiting or platform-side blocking may cause some results to return 'unknown' status
- Downstream platform unavailability may inflate unknown_count
