Afriref: cited government reference data

get_series

Read-onlyIdempotent

PAID ($0.003). Current value of a reference series — e.g. series=policy-rate, vat, minimum-wage. Every value carries its official source citation, effective date, last-confirmed date and staleness flag. Pass api_key if you have one (instant card checkout at /pricing); otherwise the response explains how to pay via x402. Every GH series is free to try. After a 200, bind get_changes (free poll) or register_alert (HMAC push; Register: $0 · Delivery after trial: $0.05) on this series so a later gazette does not silently retire the value.
