How this service works
The average interest rate the US Treasury currently pays on its outstanding debt, broken out by security (Treasury Bills, Notes, Bonds, TIPS, FRNs, savings, and the marketable/total aggregates) for the latest reported month, in percent. No ticker needed. A read on the government's cost of borrowing that complements the /treasury-yields curve. Sourced from the US Treasury (FiscalData).
Output
Returns average interest rate data for US benchmarks such as the Federal funds rate, Treasury yields across maturities, and potentially mortgage or prime rates. Likely includes rate values, dates/periods, and rate category identifiers.
Example use cases
Macro dashboard rate monitoring
“Pull the latest average US interest rates including the Fed funds rate and Treasury yields so I can update my macro dashboard.”
Monetary policy research
“I'm researching the Fed's rate cycle — can you get me the historical average Fed funds rate data so I can see how rates have changed over the past few years?”
Fixed income portfolio context
“I need current average Treasury yield data across maturities to benchmark my bond portfolio — can you fetch that for me?”
Technical details
Endpoint
GEThttps://agents.x402stock.xyz/api/v1/avg-interest-ratesWhen to prefer
Choose this endpoint when you need programmatic, pay-per-use access to US average interest rate data without API key setup. Ideal for AI agents that need macro rate context (Fed funds, Treasury yields) on demand with autonomous micropayment via USDC/x402. Prefer over free alternatives when reliability and breadth of rate types matter, or when building autonomous agents that self-fund API calls.
Side effects
- Invalid or unrecognized properties parameter returns an error
- Payment failure or insufficient USDC balance blocks the request
- Unsupported rate category or time range returns empty or error response
- Network timeout from upstream x402stock API
- Malformed request body causes 400-level error
