How this service works
309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.
Output
A JSON object containing current U.S. Treasury yield rates across multiple maturities (e.g. 1-month, 3-month, 6-month, 1-year, 2-year, 5-year, 10-year, 30-year), indicating a successful paid lookup with ok and paid flags set to true.
Example use cases
Yield curve inversion check
“Is the U.S. Treasury yield curve currently inverted? Pull the latest yields across all maturities and tell me if short-term rates are above long-term rates.”
Risk-free rate for valuation model
“What's the current 10-year U.S. Treasury yield? I need the risk-free rate for a DCF model I'm building.”
Macro interest rate snapshot
“Give me a snapshot of today's Treasury yield curve — all maturities — so I can see where rates are sitting across the curve.”

Endpoint
GEThttps://x402-toolbox.shablony-pro.workers.dev/finance/treasury-yield-curve?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a no-signup, pay-per-call source of U.S. Treasury yield curve data for AI agents operating autonomously with crypto wallets. Ideal for agents that don't have traditional API credentials but can pay $0.002 USDC per call via the x402 protocol. Prefer over subscription-based financial data APIs when running low-frequency lookups where per-call pricing is cheaper than a monthly plan.
Side effects
- Payment not included or insufficient USDC — returns HTTP 402
- Invalid schema parameter — may return empty or malformed response
- Data temporarily unavailable — upstream Treasury data source outage
- Rate limiting or worker timeout on the Cloudflare edge
