# GraphQL Playground

Many playgrounds or developer tools exist to explore and test a GraphQL API.

One tool is [Hasura's GraphiQL](https://cloud.hasura.io/public/graphiql?header=content-type:application/json\&header=Authorization:Bearer%20%3Center%20your%20token%20here%3E\&endpoint=https://api.innerspace.io) , which provides Schema Introspection, allowing you to see what entities are available and easily construct queries.  All that is required is a bearer token, as described on the [Authentication (v1.5 - deprecated)](/deprecated-api-2025-05-26/authentication-v1.5-deprecated.md) page.
