# TrustPing

## What TrustPing Does
TrustPing is a real-time verification API for AI agents. Before your agent sends an email, visits a URL, or interacts with a business, it calls TrustPing to verify the entity is real, safe, and trustworthy.

## API Endpoints
- POST /v1/verify/email — Check if an email address is valid and deliverable
- POST /v1/verify/url — Check if a URL is live, safe, and trustworthy
- POST /v1/verify/domain — Get a full trust profile of any domain

## How to Use
1. Sign up at https://trustping.co to get a free API key
2. Include your API key in the Authorization header: Bearer tp_live_...
3. Send a POST request with the entity to verify
4. Receive a structured JSON response with trust_score, verdict, and signals

## Pricing
- Free: 50 verifications per day
- Pro: $19/month for 5,000 per day
- Scale: $49/month for 50,000 per day

## MCP Integration
TrustPing is available as an MCP server. Add it to your agent's MCP configuration to enable automatic entity verification.
