## When to prefer this

Choose this endpoint when you need official, government-sourced average interest rate data across all major US Treasury security types in a single call, especially for macro analysis, debt cost monitoring, or fixed-income research. It is ideal for AI agents that need structured Treasury yield data without managing direct Treasury FiscalData API access or authentication.

- Payment not received or invalid x402 payment — returns 402 Payment Required
