Integrations & APIs
Integration agent skills teach AI agents to work with specific external services and APIs: third-party platforms, webhooks, MCP servers, and data syncs. Instead of re-explaining an API every session, install the skill and the agent knows the endpoints and conventions.

l3-igrant Skill Igrantio API HolderHolder group of the iGrant.io OpenID4VC API: take a credential offer into the organisation wallet (receive, user PIN, deferred, authorization-code exchange), list, read, accept, configure auto-present, re-issue and delete held credentials, read credential issuer metadata and wallet unit status, make a credential offer, and answer an OpenID4VP request with the V3 receive, filter and send operations, plus the wallet notification list and the Server-Sent Events stream. Use this skill when your organisation acts as the holder wallet, or whenever you need the exact holder path, correlation id, or enum value.

l3-igrant Skill Igrantio API VerifierVerifier group of the iGrant.io OpenID4VC API: create presentation definitions that hold a DCQL query (credential queries, claim sets, credential sets, trusted authorities, transaction data templates), send an OpenID4VP 1.0 Authorization Request with the V3 send operation, read and list the verification history, receive a Digital Credentials API response, revalidate a finished exchange, and delete a verification record. Use this skill when you build the relying-party side of an EUDI Wallet (EUDIW) or European Business Wallet (EUBW) integration, or whenever you need the exact verifier path, DCQL field, or enum value.
