Bittensor Finney RPC Endpoint & API

Connect directly to Bittensor Finney through OnFinality's managed Subtensor RPC over HTTPS and WebSocket. Query TAO balances, subnet and validator state, monitor miners, build analytics, and access historical chain data without operating your own Bittensor node.

btcli -n wss://bittensor-finney.api.onfinality.io/public-ws \ query metagraph --netuid 1 --json

btcli accepts a custom WebSocket endpoint through --network, allowing Bittensor CLI workflows to query Finney through OnFinality instead of the default RPC.

Query Bittensor Subnets

Bittensor applications often need chain data associated with a specific netuid: subnet metadata, metagraph state, validator/miner registrations, weights, stake and hyperparameters.

btcli query metagraph --netuid 1

Bittensor RPC for Validators and Miners

Validators

Bittensor validators rely on consistent access to Subtensor chain state to monitor subnet activity, evaluate miners, manage staking-related workflows, and publish or inspect weights.

Metagraph data — monitor UIDs, hotkeys, validator/miner state and subnet participants
Weights — query current on-chain weight information
Subnet state — monitor subnet configuration, hyperparameters and registrations
Staking data — query TAO stake and delegation-related chain state
Finalized chain state — use finalized data for workflows that require stronger consistency
WebSocket RPC — subscribe to chain updates without continuously polling HTTP endpoints

Miners

Miners can use Bittensor RPC to monitor their on-chain identity and registration status across the subnets where they participate.

Registration status — verify whether a hotkey is registered on a subnet
UID and hotkey data — query miner identity and current subnet position
Subnet membership — monitor participation across specific netuids
Metagraph data — inspect miner and validator state for a subnet
Emissions and rewards-related data — access relevant on-chain state used for monitoring earnings and subnet economics
Chain monitoring — track blocks and state changes through HTTP or WebSocket RPC
