How do you extract knowledge from the Bittensor chain? The [taostats API](https://beta.taostats.io/docs/api-reference#/)  gets you 99.9% of the way there.

There are some calls that may require direct access into the chain.  There is a [Python SDK](https://github.com/opentensor/bittensor) for some direct access. But not even that gets you everything.

The [Taostats RPC Connection](https://beta.taostats.io/docs/api-reference) gives you direct access into the chain.  From the chain you can make many requests for granular information.

## how RPC works:

See the [API documentation](https://beta.taostats.io/docs/api-reference) for endpoint details.

With just an API key from taostats, you can make RPC calls using the [Bittensor SDK](https://docs.learnbittensor.org/sdk/bt-api-ref)
