Osmosis
Osmosis (OSMO) is a Cosmos SDK Layer 1 secured through proof-of-stake consensus with CometBFT, built as an application-specific chain for decentralized exchange and liquidity. Chain logic runs through Cosmos SDK modules and CosmWasm contracts, while full nodes execute transactions and maintain account, pool, position, staking, governance, IBC, and contract state. This Cosmos SDK and CometBFT architecture aligns Osmosis with other interchain networks, making Cosmos transactions, module queries, and IBC state the shared primitives for application integrations.
Osmosis API Methods and Endpoints
NOWNodes exposes Osmosis's interface, plus a few others, depending on what your integration needs: JSON-RPC for reading chain state and broadcasting transactions, and WSS (WebSocket) for real-time subscriptions and events.
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.
