Masterworks GraphQL API is published by [Masterworks](https://apis.io/providers/masterworks/) on the [APIs.io](https://apis.io/) network. Tagged areas include Art Investing, Alternative Investments, GraphQL, Securities, and Fintech. The published artifact set on APIs.io includes authentication docs.

The single GraphQL endpoint behind the Masterworks web and mobile apps, covering art offerings, artists, auction and repeat-sale data, contributions, agreements and e-signature, KYC and accreditation, payments and payouts, the secondary-market exchange, art events, activity feeds, referrals and internal notification tooling. It is an undocumented first-party backend, not a published developer API: anonymous schema introspection is enabled, but every data field is guarded by an @authenticate directive and returns HTTP 200 with an errors[].extensions.code of invalidAuthentication (status 401) when called without a token.
