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 per-platform list of results with status (taken/available/unknown) and profile URL for each of 20+ platforms, plus aggregate counts for taken/available/unknown and an overall availability grade and score.

Example use cases

Example prompt

“Can you check if the username 'morningbloom' is available across social media and developer sites — I want to know which platforms already have someone registered under that handle?”

Technical details

Endpoint

GEThttps://netintel-production-440c.up.railway.app/username-check/lookup?utm_source=zero.xyz

When to prefer

Use this endpoint when you need to check username availability or presence across many platforms in a single call rather than manually querying each platform. Ideal for brand handle scouting, identity research, finding a person's social presence, or verifying name availability before registration. Better than single-platform checks when breadth of coverage matters.

Side effects

Username missing or blank — returns 400 validation error
Username exceeds 50 characters or contains invalid characters — returns validation error
Platform probe timeout — individual platforms may return 'unknown' status
Service temporarily unavailable — 5xx error
Payment not included or insufficient — 402 Payment Required
