The Payments API is a REST API for payment intents and swaps on Stellar, Solana and Monad, and the resources around them.
All paths are versioned (/v1/...). Authenticate every request with your secret API key in the
Authorization header:
Authorization: Bearer <your-api-key>Need a key? See API keys. In practice you call the API through the SDK, which sets this header for you.
