Technical details
Endpoint
GEThttps://finance-api.kdlcfa.workers.dev/us30y-yieldWhen to prefer
Choose this endpoint when you need a quick, low-cost lookup of the US 30-year Treasury bond yield and real-time precision is not required. Ideal for dashboards, research, DCF modeling, and macro monitoring where delayed data (typical 15-20 min delay) is acceptable. Prefer over scraping Yahoo Finance directly due to the clean API abstraction. If you need real-time tick data or official Treasury data, use a dedicated Bloomberg or TreasuryDirect feed instead.
Side effects
- Yahoo Finance data unavailable or rate-limited — upstream dependency failure
- Stale or delayed data returned without clear timestamp — user may not realize data is not real-time
- Payment not processed (x402 micropayment required at $0.01 USDC) — request rejected without valid payment header
- Malformed response if Yahoo Finance changes its data format
