    Quick Start

    Authenticate

    curl -X POST "https://api.verifypulse.com/v1/auth/login" -H "Content-Type: application/json" -d '{"email":"[email protected]","password":"your-password"}'

    Request a Number

    curl -X POST "https://api.verifypulse.com/v1/numbers/request" -H "Authorization: Bearer YOUR_API_KEY" -H "Content-Type: application/json" -d '{"service":"generic","country":"US"}'

    Check Messages

    curl -X GET "https://api.verifypulse.com/v1/sms/receive?numberId=NUMBER_ID" -H "Authorization: Bearer YOUR_API_KEY"

    Core Endpoints

    • POST /auth/login — Authenticate and get a token
    • POST /numbers/request — Provision a number for a service and country
    • GET /sms/receive — Poll for incoming messages
    • POST /webhooks — Configure webhooks to receive SMS in real time
    • DELETE /numbers/{id} — Release a number when done

    Security & Rate Limits

    • Rotate API keys regularly and never embed them in client apps
    • Use webhooks over polling for scale; implement exponential backoff
    • Validate payload signatures on webhook deliveries
    • Leverage IP allowlisting for backend integrations
