XCusty builds APIs for transfer initiation, custody connectivity, transaction status, wallet operations and reconciliation. These interfaces allow treasury tools, customer platforms and internal applications to use blockchain capabilities through a defined integration layer.
Transfer lifecycle interfaces
The API specification identifies how a business creates an instruction, supplies required approval information and follows its progress. Responses distinguish request acceptance from execution and settlement. A unique business reference helps connect the request with subsequent events and financial records.
Duplicate prevention is part of the design. Where supported by the integration, idempotency controls allow a client to repeat a request safely after a timeout without unintentionally creating a second transfer. Ambiguous provider responses are investigated through status reconciliation before a new transfer is attempted.
Events and operational reliability
Webhook and event services can notify client systems when status changes. Delivery acknowledgment, retry behavior and event ordering are documented so that consumers can handle repeated or delayed notifications. Polling and reconciliation provide an additional way to check important events.
The integration layer can also handle rate limits, provider outages and differences in data formats. Credentials, permissions and environment separation are defined for development, testing and production.
Representative API domains
| Domain | Typical functions |
|---|---|
| Identity and access | Authentication, service permissions and credential rotation |
| Wallets and accounts | Address registration, balance retrieval and account mapping |
| Transfers | Instruction submission, approval status and transaction tracking |
| Custody adapters | Provider requests, account synchronization and signing handoffs |
| Reporting | Transaction exports, reconciliation results and exception records |
Handover for the client team
Delivery can include an interface specification, example requests, a test environment, integration guidance and error-handling documentation. Versioning and change-notification arrangements are agreed so that future updates can be introduced without unexpected disruption to connected applications.
