API Reference

The Samva API is organized around REST principles with an agent-native architecture. All API requests return JSON responses and use standard HTTP response codes.

Base URL

https://samva.app/api/v1

For development:

https://staging.samva.app/api/v1

Authentication

All API requests require authentication via API key. Include your API key in the X-API-Key header:

curl -H "X-API-Key: your-api-key-here" \
  https://samva.app/api/v1/messages

Getting Your API Key

1. Log in to your Samva account
2. Navigate to Settings → API Keys
3. Click Create API Key
4. Copy the API key (it's only shown once)

Security Best Practices

• Never commit API keys - Use environment variables
• Rotate regularly - Generate new keys periodically
• Use separate keys - Different keys for dev/staging/prod
• Revoke unused keys - Delete keys that are no longer needed
