About Banque Centrale de Mauritanie

The Banque Centrale de Mauritanie publishes a daily reference rate for the ouguiya against 19 currencies — the US dollar, euro and the other majors, the Gulf and Maghreb units, the West African CFA franc and the SDR — fixed after the morning interbank session. The ouguiya floats within a managed band against the dollar, and the bank's reference rate is the official conversion Mauritanian customs, the tax administration and the banks apply; the series in our API runs from December 2023.

Why use the official Banque Centrale de Mauritanie rate?

When an auditor or tax office in Mauritania asks which rate you used, "the MRU mid-market rate at 14:32" is not an answer — the official rate published by Banque Centrale de Mauritanie for that date is. This API returns exactly those published figures, stamped with the bank's own rate_date; on weekends and holidays the most recent published table is returned, as compliance rules expect.

Pairs the bank doesn't print directly are resolved from its table (inverse or cross via MRU) and explicitly flagged "derived": true — so what the bank printed and what was computed are never confused.

Endpoints

• GET /api/v1/central-bank/bcm/latest — latest table or single pair (all plans)
• GET /api/v1/central-bank/bcm/{YYYY-MM-DD} — the table for any date (paid plans)
• GET /api/v1/central-bank/bcm/history — time series, up to 5,000 rows (paid plans)
• GET /api/v1/central-bank/bcm/availability — publication calendar: the dates the bank actually published (all plans)

Full parameter reference in the API documentation. Every request counts toward your plan's monthly quota — rates change once per business day, so caching a published table locally makes a small quota go far.
