**APIs profiled:** 10

Aptos is a Move-based Layer 1 blockchain platform that exposes a REST API for reading on-chain state and submitting transactions, a GraphQL Indexer API for high-level queries over processed blockchain data (NFTs, objects, custom Move contracts), and a gRPC Transaction Stream for real-time and historical event feeds. Public endpoints are provided by Aptos Labs for mainnet, testnet, and devnet; enhanced rate limits are available through Geomi (formerly Aptos Labs Developer Portal).
