How access works

Public catalogs are readable without credentials. Your backend adds a builder API key for authorized requests; users sign the action they are taking. Private shipping data also requires a wallet verification message and a scoped session. Start with authentication for credential requirements and networks and contracts for chain selection and contract addresses. Sign in with Renaiss is a separate, optional OIDC integration for apps that want to offer Renaiss accounts as a login method.
Renaiss is an independent marketplace for authentic collectible cards. It is not affiliated with or endorsed by The Pokémon Company, Nintendo, Shueisha Inc., Eiichiro Oda or related entities.
