How this service works
Monthly average interest rates the US Treasury pays across Bills, Notes, Bonds, TIPS and other marketable securities, from FiscalData (keyless JSON). Serves autonomous fixed-income agents, debt-service-cost models, and agent-to-agent yield-analysis bots tracking US government borrowing costs. First 3 calls FREE per wallet — send header X-WALLET: 0x<addr>. No charge on upstream failure.
Output
Returns a JSON object with an 'ok' status flag, a niche identifier ('us-treasury-avg-interest-rates'), and a result payload containing monthly average interest rate records for US Treasury marketable securities including Bills, Notes, Bonds, TIPS and other instruments — sourced from FiscalData. Records include security type, maturity, rate percentage, and time period fields. Supports pagination, sorting, and filtering.
Example use cases
Debt service cost monitoring for fiscal models
“I need the most recent monthly average interest rates the Treasury pays across all marketable securities — Bills, Notes, Bonds, and TIPS — so I can update my government debt service cost model. Give me the first page sorted by date descending.”
Historical TIPS yield trend analysis
“Can you pull historical average interest rates specifically for Treasury TIPS securities? Filter by TIPS and sort by record date so I can analyze how real yields have trended over the past few years.”
Fixed-income agent yield benchmarking
“For my fixed-income benchmarking dashboard, fetch the average rates the US Treasury pays on short-term Bills versus long-term Bonds. Get page one of results sorted by security type so I can compare borrowing costs across maturities.”
Technical details
Endpoint
POSThttps://us-treasury-avg-interest-rates.hergertsynthora.com/serviceWhen to prefer
Choose this endpoint when you need programmatic, agent-accessible access to official US Treasury average interest rate data by security type on a per-call basis without managing API keys. It is ideal for autonomous fixed-income agents, debt-service-cost models, and yield-analysis bots that need FiscalData figures in a structured JSON format with filtering, sorting, and pagination support. Prefer this over direct FiscalData calls when operating in an x402 micropayment-enabled agent environment.
Side effects
- Invalid filter syntax returns an error or empty result set
- Upstream FiscalData API unavailability causes service to fail or return stale data
- Page parameter out of range returns empty results
- Malformed sort field returns an error or default ordering
- Payment not processed (x402) results in 402 response and no data returned
