What is Trustping?

Trustping is a real-time entity verification API for AI agents. It checks whether an email, URL, or domain is real, safe, and trustworthy, returning a structured JSON response with a trust score and verdict in under a second.

How to use Trustping?

Call the Trustping API via its MCP tools (trustping_verify_email, trustping_verify_url, trustping_verify_domain) or the REST endpoints directly. For testing, sign up at POST /v1/auth/signup for 50 free calls per day. For production, use POST /v1/access/instant with a Stripe payment method to get an API key immediately at $0.003 per call.
