An Italy–Germany 10Y spread API returns the BTP–Bund gap in basis points as JSON so a rates dashboard does not subtract yields in the browser. On Bonds-API that is GET /api/v1/spread with country=IT, benchmark=DE, maturity=10Y, and query api_key (not Bearer).
Starter is $19/mo (1,000 requests) with a 7-day trial. Pro is $49 / 10k. Docs: bonds-api.com/docs. MCP: https://mcp.bonds-api.com (bonds-api.com/mcp 404s).

Italy 10Y is 3.78, Germany 10Y is 3.00, spread is 78.0 basis points on 2026-04-14. That is the documentation fixture — copy the curl for a live print. Keys on latest are {CC}_{TENOR} (for example IT_10Y / DE_10Y) if you pull levels instead of the spread helper.

Same api_key. Curve is the tenor stack for one country; spread is a pairwise gap. Historical / timeseries / intraday / fluctuation live on other /api/v1/… paths in the docs.

FAQ
Is this Fed Funds or SOFR?
No. Those H1s belong to Interest Rates API. This post is a sovereign 10Y spread.
