Aptos

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).

Aptos publishes 7 APIs on the APIs.io network, including Accounts API, Blocks API, Events API, and 4 more. Tagged areas include Blockchain, Web3, Move, Layer 1, and Cryptocurrency.

The Aptos catalog on APIs.io includes 2 JSON-LD contexts and 1 Spectral governance ruleset.
