Designing a Schema
The Fuel indexer uses GraphQL in order to allow users to query for indexed data. In this chapter, you can find information on how to leverage our supported features to efficiently get the data you want.
⚠️ Please note that the Fuel indexer does not support the full GraphQL specification; however, we do our best to reasonably support as much as we can.
Supported Functionality
While we do our best to maintain compliance with the GraphQL specification and parity with other implementations, there are a few things that are under development or will not be implemented. Here's a table describing our GraphQL functionality:
