# GraphQL Our [GraphQL](https://graphql.org/) API allows querying the entire Tezos Domains catalogue of data including the historic versions of each entity at each block. For more information, you can check: * Our GraphQL [playground site](https://api.tezos.domains/playground) * The [current schema](https://api-schema.tezos.domains/) Our API exposes list data according to [Relay Connection specification](https://relay.dev/graphql/connections.htm). This makes it easy to generate client code and paginate using cursors in general. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://developers.tezos.domains/integrating-tezos-domains/graphql.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
