Metagraphed indexes Bittensor chain-direct: every subnet, block, extrinsic, account, and
on-chain event, plus derived health, economics, and market data. These guides cover the
public REST API surface by domain, with a full auto-generated reference for every endpoint.

<Callout type="info">
  New to Bittensor itself, not just this API? The [Protocol](#protocol) guides below explain
  stake-weight, registration, weight-setting, proxies, and delegation from first principles.
</Callout>

<Callout type="info" title="Keyless stays keyless">
  Every route above works with no API key, at the generous anonymous rate limits documented
  per-domain — that never changes to a paid tier. A free, wallet-verified [API key](/settings) buys
  *more* headroom (currently 5× on the chain-events/deep-history routes, with more routes to follow)
  plus a usage dashboard — it never gates anything the anonymous tier already has.
