Fetch.ai (FET) API Documentation

Fetch.ai

Fetch.ai (FET) is a Cosmos SDK-based Layer 1 secured by proof-of-stake validators, with delegated FET bonded to validators that produce and validate network state. Application logic is implemented through Cosmos SDK modules, while full nodes execute transactions and maintain account-based balances, staking, governance, and other module state. Because Fetch.ai shares Cosmos SDK and Tendermint-style infrastructure with other interchain networks, its transaction, consensus, and state-query patterns align with the broader Cosmos development model.

Fetch.ai API Methods and Endpoints

NOWNodes exposes Fetch.ai's interface, plus a few others, depending on what your integration needs: Cosmos REST for account, staking, governance, and transaction queries, Tendermint RPC for consensus and block data, WSS (WebSocket) for real-time subscriptions and events, and gRPC for protocol-defined service calls.

Browse the interfaces below for endpoint details, request parameters, response formats, and integration examples. Create an API key, select Mainnet or Testnet, choose the required interface, and start sending requests from your application.
