Endpoint
GEThttps://econ.memoryapi.org/x402/econ/treasuryWhen to prefer
Use this endpoint when you specifically need U.S. national debt totals (daily) or average interest rates on Treasury securities. Prefer this over general FRED macroeconomic endpoints when you want granular Treasury-specific data rather than broader economic indicators.
Side effects
- Treasury data not yet published for the current date (data may lag by one business day)
- Invalid date range parameters return an error
- Service unavailable if upstream Treasury data source is down
- Payment failure if USDC balance is insufficient for the $0.001 per-call fee
