List activity
Returns a deterministic merged cash-activity projection only when both upstream read windows are provably complete. It is customer-wide and does not claim account-ledger semantics.
Authorizations
Per-request RFC 9449 DPoP proof signed with ES256. Protected requests use Authorization: DPoP your_access_token_here. Create a new proof for the exact method and normalized target URI, and include the server nonce when challenged.
OAuth 2.0 with RFC 9700 security practices. Discover exact environment endpoints from /.well-known/openid-configuration and /.well-known/oauth-authorization-server, and discover the resource from /.well-known/oauth-protected-resource. Authorization-code clients use PKCE S256, the exact environment resource, nonce with openid, and DPoP binding. Confidential clients also require PAR and private_key_jwt. Access and refresh tokens are sender-constrained with DPoP. purchases:execute is unavailable and omitted from this scope registry.
