During November 2025, the developer contributed to the DefinitelyTyped/DefinitelyTyped repository by enhancing the invity-api type definitions. They introduced a new termsUrl field to provider information interfaces, allowing API clients to access providers’ terms of service directly from API metadata. This addition aimed to improve transparency and foster user trust by making provider terms easily accessible for client integration. The work was implemented using TypeScript and focused on API development and type definition extension. While the contribution was limited to a single feature and did not involve bug fixes, it addressed a clear business need for clarity and trust.
