    **Sandbox API** — clients integrate against this surface to exercise happy
    and unhappy paths without consuming real KYC/PSP credits or moving real
    money. Customer KYC, banking partners, and crypto custody are stubbed;
    org-level KYB runs against real providers. Simulation endpoints under
    `/v2/sandbox/*` drive specific scenarios.


    Internal and portal endpoints are excluded from this spec.

            object identifier but received a value that does not match the
            expected format.


            **VALIDATION_ERROR**: The request body or query parameters failed
            validation. One or more fields have invalid values, missing required
            properties, or incorrect types. Multipart file uploads that fail at
            the multipart-parser layer (unexpected form-field name, too many

            syntactically valid JSON.


            **IDEMPOTENCY_KEY_REQUIRED**: This endpoint requires an
            Idempotency-Key header to prevent duplicate processing. Generate a
            unique key per logical request and resend the request.


            **IDEMPOTENCY_KEY_INVALID**: The Idempotency-Key header value did
            not match the required shape (1-128 characters, letters / digits /
            underscore / dot / colon / hyphen).


            **IDEMPOTENCY_BODY_TOO_NESTED**: The request body exceeds the
            maximum nesting depth allowed by the idempotency fingerprint hasher.
            Deeply-nested arrays or objects are rejected as a malformed payload.
