PortX ORCA (Open Reusable Core API)

ORCA is PortX's universal, standards-based REST contract for US banking core connectivity — an ISO 20022-aligned JSON/REST specification covering bank account opening, maintenance, closing and reporting, plus parties, transactions, cards, loans, collaterals, ledger accounts, internal transfers and credit transfers. The published OpenAPI 3.1.0 description carries 112 operations across 16 tags. ORCA is deployed as a per-institution connector (for example a symitar-orca or fco-premier-orca instance), so the contract's servers block is templated rather than naming one shared host. Access to the specification is governed by the ORCA Evaluation and Access License.
