How this service works
Gloom is a free, open-source finance terminal for desktop and TUI with charts, news, filings, portfolios, alerts, and plugins.
Output
Returns a JSON object with the curve metadata (id, basis, label, country), an asOf date, an optional requestedDate, and an array of points each containing a tenor label (e.g. '1M', '10Y'), years equivalent, and yield percentage. Example: 1M tenor at 4.04% yield.
Example use cases
Fixed income portfolio rate check
“What does the US Treasury par yield curve look like right now? Give me all the tenor points from 1-month out to 30-year.”
Yield curve inversion monitoring
“Fetch the current US Treasury yield curve so I can check whether the 2s10s spread is inverted — give me at least the 2-year and 10-year yields.”
Historical yield curve snapshot
“Get me the US Treasury yield curve as of September 29, 2026 — I need the full set of par yield points for that date.”
Technical details
Endpoint
GEThttps://api.gloom.sh/v1/yield-curves/%7Bcurve%7D?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, machine-readable yield curve data (par rates by tenor) for a named curve such as US Treasuries, especially when building fixed income analysis, macro dashboards, or monitoring yield curve shape. Prefer this over scraping financial sites when you need clean JSON with tenor-to-yield mappings. It is open-source and priced per-call at $0.06 USDC via x402, making it suitable for on-demand agent queries rather than bulk historical pulls.
Side effects
- Invalid or unsupported curve ID returns an error or empty data
- Future or unavailable date returns null or error response
- Malformed curve path parameter causes 400/404
- Payment not completed (x402 flow) blocks data access
- Rate limiting or quota exceeded returns 402/429
