The title asks for Namibia sovereign yields. Bonds-API country codes are ISO-2 on GET /api/v1/latest?countries=&maturities= with query api_key. Namibia (NA) is not in the published country catalog (US, DE, ZA, NG, KE, …). Call countries=NA only if you want the live error; for a working Africa print use ZA (South Africa) or start with US.
Starter is $19/mo with a 7-day trial. MCP: mcp.bonds-api.com. Register: bonds-api.com/register.
Request: latest US 10Y (catalog country)
curl "https://bonds-api.com/api/v1/latest?countries=US&maturities=10Y&api_key=YOUR_API_KEY"
