Endpoint

Use this endpoint when an AI agent needs to programmatically place an outbound phone call from a specific provisioned Palmyr number, especially in workflows where crypto-native payments (USDC on Solana or Base) are preferred over traditional billing. Ideal for autonomous agents that need to reach humans by voice without manual intervention.
