To scope requests to a specific entity, include the `x-entity-id` header. Use the `/api-keys/accessible-entities` endpoint to list all entities accessible by your API key. ### Error Responses Errors return JSON with `code`, `message`, and `debug_message`. The `code` aligns with FDX where possible; use `debug_message` for troubleshooting only. Common error codes: - `500`: Internal server error - `501`: Subsystem unavailable - `503`: Scheduled maintenance - `601`: Data not found - `602`: Customer not authorized - `701`: Account not found - `703`: Invalid input (including invalid date ranges) - `704`: Account type not supported - `705`: Account is closed - `801`: Transaction not found contact: name: Meow url: https://meow.com/ email: support@meow.com version: 1.0.0 license: name: Proprietary url: https://www.meow.com/terms-of-service servers: -
