**APIs profiled:** 1

Bittensor is an open, decentralized machine-intelligence network built on a Substrate blockchain (subtensor). Contributors earn the TAO token by supplying useful work to specialized subnets — miners produce, validators score, and stakers back them — with emissions distributed by Yuma Consensus. Developers do not consume a hosted REST API; they interact with the chain through the official lean Python SDK (import bittensor) and the btcli command line, which together perform every user-facing operation: wallets and keys, staking and pools, subnet creation, mining, validating, weights, proxies, multisig, and an EVM layer. The developer surface is agent-native: machine-readable catalogs of write intents, chain reads, and errors are published for discovery, with a plan/execute model, Policy guardrails, and typed results.
