Algorand Algod REST API

The Algod REST API is the primary interface for interacting with a live Algorand node. It exposes endpoints for querying account information, asset details, application (smart contract) state, pending and confirmed transactions, blocks, and state proofs. Developers can submit signed raw transactions, simulate transaction groups, compile and disassemble TEAL programs, manage catchpoint catchups, and inspect ledger supply. Authentication uses an X-Algo-API-Token header. Public archival nodes (e.g. mainnet-api.4160.nodely.dev) are freely accessible without a token on the free tier.
