- Auth: HTTP bearer

Market-implied credit context: each covered country's 10-year government bond yield and its spread, in basis points, over the German Bund and over the US 10-year Treasury. A KRESMION CALCULATION from published yields, NOT a credit rating. Monthly: both legs are the same calendar month.

Without `country`: the newest month per country, widest spread vs the Bund first; each row names the source, series and month of BOTH legs. With `country` (ISO-2, e.g. IT): that country's monthly history, oldest first, with its newest row and rank vs the Bund under `meta`.

Sources: ECB statistics (IRS) for the EU27 and the Bund leg; OECD Main Economic Indicators via FRED for AU, CA, CH, CL, GB, IL, JP, KR, MX, NO, NZ, ZA; Federal Reserve H.15 DGS10 via FRED for the US leg. The ECB yields are available free of charge at data.ecb.europa.eu. Reproduce `meta.attribution` when you quote a figure.

## Query parameters

- `country` string, nullable: ISO-2 country code (e.g. IT, FR, GB, JP). Omit for every covered country.
- `months` integer: History length in months, `country` only (default 25).

## Headers
