The Fuel indexer's GraphQL Playground is an interactive, in-browser GraphQL IDE that allows developers to easily explore and test the indexer's GraphQL API server. You can read more about the GraphQL playground in general here .
Every public indexer can access the GraphQL playground of the Fuel indexer node on which the given indexer runs, so users and devs can get to querying their data right away.
To use the GraphQL playground to explor your indices, simply start your indexer service - then open the following URL in your browser - where namespace and identifier correspond to the namespace and identifier of the index that you'd like to explore.
http://localhost:29987/api/playground/:namespace/:identifierNOTE: On initial page render, the playground throws a 500. Don't worry about this, you should still be able to query.
