Bittensor research API

Read public subnet, validator and portfolio data. These GET endpoints do not sign or submit transactions.

Subnets

GET /api/tao/subnets

Returns active subnet identities, TAO reserves, alpha prices, emissions and the finalized block used for the snapshot.

Validators and history

GET /api/tao/validators?id=1
GET /api/tao/history?id=1&range=day
GET /api/tao/history?id=1&range=week

Use a registered subnet ID. History consists of sampled archive blocks; check the response for missing samples before displaying a continuous series.

Portfolio and activity

GET /api/tao/portfolio?address=SS58_ADDRESS
GET /api/tao/activity

Supply a native SS58 address for a portfolio lookup. Position values use spot prices. Activity covers four recent finalized blocks, not full account history.

Robinhood Chain

GET /api/robinhood?address=EVM_ADDRESS

The separate EVM workspace returns network activity and, when an address is provided, ETH, WETH and USDG balances.

Availability

Check HTTP status codes and error fields. Shared RPC services can time out or limit requests. Missing data must not be treated as a zero balance.
