Create a fraud marker

Registers a DICT fraud marker for the taxpayer identified by taxIdNumber, optionally linked to a Pix key. requestId is the caller-provided idempotency key. Repeating a requestId with the same payload returns the same marker; repeating it with a different payload is rejected. The participant is determined by the authenticated tenant.

taxIdNumber · string · requerido

CPF or CNPJ (numeric or alphanumeric per IN RFB 2.229/2024) being marked, checked against BACEN/RFB check digits. Mask, surrounding whitespace, and lowercase are accepted and normalized to the canonical unformatted uppercase form before use.

key · string

Optional Pix key tied to the marker. Maximum 77 BYTES UTF-8, not characters -- the schema deliberately does not declare maxLength (OpenAPI's maxLength counts characters, which would under-bound a multi-byte key); the byte-length limit is enforced at runtime (the service implementation).

"[phone]"
