Afriref Compare — Cross-Country African Reference Data

Use this endpoint when you need to compare one specific government reference series (VAT, policy rate, minimum wage, corporate tax, CPI, etc.) across multiple African countries simultaneously with official source citations. It is the right choice over a general-purpose web search when you need structured, machine-readable, source-cited regulatory data for African markets in a single call. Prefer this over the snapshot endpoint when you only need one series across a targeted list of countries rather than all series for all countries.

• Invalid or unsupported series ID returns an error — use GET /catalog to retrieve valid series identifiers
• More than 10 country codes supplied causes a validation error
• Invalid ISO 3166-1 alpha-2 country code returns an error or omits the country
• Country not covered by Afriref's 34-country dataset returns no row or an explicit not-found entry
• Payment failure (x402) prevents the call from completing
• Stale data if a country's official source has not been re-confirmed recently — check last-confirmed date
