Use Authorization: Bearer YOUR_API_KEY
Headers
Optional client-chosen key for this request (any string up to 255 characters, e.g. a UUID). Every Croma operation is an idempotent lookup: repeating a request with the same body returns the same result and creates nothing, so retrying after a timeout or network failure is always safe. The key is echoed back in the Idempotency-Key response header so you can correlate a retry with its first attempt. Each attempt that reaches the API counts against the rate limit.
255"0f8e9a42-6b7c-4d1e-9a3f-2c5d7e8f9a0b"
Body
The company's 13-digit corporate number (法人番号), e.g. 1180301018771. The first digit checks the other twelve.
