The API provides an identity verification service. In the process, a client sends a POST request with detailed user information for verification. The ZignSec system compares this information against various data sources. It returns a response containing the match level of each piece of data, the verified age of the user, and an indication of whether the user was found in their databases. The results are itemized, giving insights into which pieces of user information fully, partially, or didn't match the data sources. **MatchLevel:** The primary response includes a MatchLevel assessment, which can be categorized as HIGH, MEDIUM, or LOW. This rating reflects the degree of similarity between the provided input data and the best-matched information in the specified country. - **HIGH:** Represents a very strong match, indicating that the data item (e.g., user) is highly likely to refer to the same entity (e.g., individual). - **MEDIUM:** Indicates a match that requires a business decision. It suggests that the data item (e.g., user) may be accepted but should undergo manual inspection. - **LOW:** Signifies a weak match, indicating that the data item (e.g., user) should not be accepted due to significant dissimilarity. **ValidationMethod and Pricing Level:** For detailed information regarding pricing levels, please reach out to our sales team. **ValidationMethods:** 1. **Validate Identity ID1x1:** This method performs queries until a match is found in a single data source. It allows validation of identity fields such as Name, National ID, and Date of Birth. Additional details can be found in the document "zignsec_id_1x1-1," "NID matchguide" for Name, National ID, and Date of Birth validation, "NAI_Match Guide" for Name_Address_ID validation, and "NAI_v2_Match Guide" for further Name_Address validation. 2. **Validate Identity ID2x2:** This method conducts queries until a match is found in two data sources and is particularly suitable for the UK. For more information, please refer to "MatchGuide for Validate_Identity_Default_2x2." It is possible to customize the service to verify particular data fields based on user requirements. Please note that the availability of different tenants varies by country. You can inquire about the coverage with our sales or support services. Additionally, you can select a specialized query configuration by specifying the ValidationMethod parameter. For the correct setup, please contact ZignSec.
