This GraphQL API offers a high-level, opinionated GraphQL interface to read state from the Aptos Blockchain. It’s ideal for interacting with NFTs, Aptos Objects, or custom Move contracts. Learn more about the Indexer-powered GraphQL API here.
Transaction Stream API →
This GRPC API streams historical and real-time transaction data to an indexing processor. It’s used by Aptos Core Indexing and can also support custom app-specific indexing processors for real-time blockchain data processing. Learn more here.

Aptos Labs operated API Deployments
Aptos Labs operates a deployment of these APIs on behalf of Aptos Foundation for each Aptos Network and makes them available for public consumption.
At the moment there are 2 sets of Aptos Labs API deployments:
