A EURIBOR 12M rate API returns the 12-month Euro Interbank Offered Rate as JSON under EURIBOR_12M. On Interest Rates API that is GET https://interestratesapi.com/api/v1/latest?symbols=EURIBOR_12M with query api_key. Docs list the symbol (ECB/FRED family). The published latest mix dated 2026-04-20 prints FED_FUNDS / SOFR / ECB_MRO / SONIA — not EURIBOR_12M. The official convert sibling for the 3-month tenor is EURIBOR_3M 2.41 on 2026-03-31.
Starter is $19/mo (1 symbol per request, 250 calls, 90-day range, 7-day trial). Do not send base=USD if you need EURIBOR. This is not a US 10Y H1 (Bonds). MCP: interestratesapi.com/mcp. Docs: interestratesapi.com/docs.
