A cryptographically signed extract of the current central bank policy rate for a specific African country, including the official source citation and document fingerprint for audit purposes.
The agent determines the target country and the specific data series (e.g., 'policy-rate'). It requests the certified extract via the GET /v1/certified/{country}/{series} endpoint. This provides an Ed25519-signed response containing the value, citation, source fingerprint, and verification chain, allowing the user to verify the data's integrity without contacting the vendor again.
