How this service works
Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).
Output
Returns current US Treasury yield rates across standard maturities (e.g. 1-month, 3-month, 6-month, 1-year, 2-year, 5-year, 10-year, 30-year), likely as a JSON object with maturity labels mapped to yield percentages. Payment is settled in USDC on Base via the x402 protocol.
Example use cases
Yield curve monitoring for portfolio
“What do US Treasury yields look like right now across maturities? I need the full yield curve to evaluate my bond portfolio positioning.”
Risk-free rate for DCF model
“Pull the current 10-year Treasury yield for me — I need the risk-free rate to plug into a discounted cash flow valuation.”
Yield spread alert for macro research
“Get me the latest Treasury yields so I can calculate the 2-year to 10-year spread and see if the curve is still inverted.”

Endpoint
GEThttps://acp-x402-discovery.onrender.com/x402/treasury-yieldsWhen to prefer
Choose this endpoint when you need pay-per-call, micropayment-settled Treasury yield data without a subscription, particularly in agentic or automated workflows that use the x402 USDC payment protocol on Base. It is appropriate when you want lightweight, on-demand access to US government bond yield data at $0.001 per call. Prefer alternatives (e.g. FRED API, TreasuryDirect) if you need guaranteed uptime, rich historical data, or free access without crypto payment infrastructure.
Side effects
- 402 Payment Required — x402 payment header missing or insufficient USDC balance
- 503 Service Unavailable — endpoint hosted on Render free tier may cold-start or go offline
- Empty or stub response — response schema is minimal ({}) so actual field names are undocumented
- Rate or data staleness — unclear data freshness guarantees
- Malformed input schema — input schema appears to be a passthrough with no validated parameters
