What problem does it solve? Verifying that a company legally exists requires requesting the correct claims from a business wallet, but building a valid DCQL query demands exact credential types, doctypes, namespaces, and claim paths that are easy to get wrong. This Skill supplies the verified query template for the Certificate Of Registration credential so KYB and business onboarding checks work the first time. ## Core Features & Use Cases - Ready-made DCQL claim paths: Provides the exact claim paths for registered name, legal form, activity, registration date, legal status, organisation number, and registered address across dc+sd-jwt, jwt_vc_json, and mso_mdoc formats. - iGrant.io API integration: Shows how to create a presentation definition with POST /v2/config/digital-wallet/openid/sdjwt/presentation-definition and send the verification request with the V3 send operation. - Format-specific meta rules: Documents the correct meta keys per format (vct_values, type_values, doctype_value) and the org.iso.18013.5.1.cor doctype for mdoc. - Use Case: When onboarding a supplier with a European Business Wallet, use this Skill to build a presentation definition that asks the wallet for the company registration extract and reads the disclosed claims from the verification history record. ## Quick Start Ask your agent to build an OpenID4VP verification request for the Certificate Of Registration credential using the igrantio DCQL query skill with the dc+sd-jwt format.
