POST /verify-company

Fields that are marked with an asterisk (*) are mandatory.

• The API can only accommodate one company information per request.

• Company Information Requirements:

  • At least one of the two fields, company_name or company_identifiers, must be provided.

  • If both fields are provided, company_identifiers will take precedence in the certified entity matching algorithm.

• Match Rate Value:

  • The default rate value is set to 100.

  • The minimum acceptable rate value is 80, regardless of whether a lower threshold is specified.

  • Valid rate values range from 80 to 100, in increments of 5.

  • Any rate value exceeding 100 will automatically be capped at 100.

• Response value:

  • The API will return a single matched company record with its certificates.
