Documentation
Every guide to Metagraphed's public Bittensor registry API — subnets, the metagraph, blocks, extrinsics, accounts, chain events, economics, search, webhooks, and the on-chain protocol concepts behind them. No API key required for any of it.
Last updated
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.
New to Bittensor itself, not just this API? The Protocol guides below explain stake-weight, registration, weight-setting, proxies, and delegation from first principles.
Core domains
Subnets
Structure, lifecycle, market, decentralization, and curation — everything about a subnet except who's on its metagraph.
Subnet metagraph & validators
The live neuron table, per-UID trust/incentive/consensus/dividends, and the global validators surface.
Blocks
Block detail, extrinsics, events, block-production analytics, and the runtime-version timeline.
Extrinsics
The on-chain call feed, root-origin governance/hyperparameter changes, and sudo calls.
Accounts
Identity, balance, holdings, activity feeds, network participation, and stake movement for one SS58 address.
Chain events reference
The Postgres deep-history all-events tier — params, response shapes, and the two-store split.
Chain analytics
Chain-wide rollups and leaderboards over activity, transfers, stake movement, weights, and concentration.
Economics
The dynamic-TAO per-subnet snapshot and network-wide daily time series — alpha pools, emission share, FDV.
Health & readiness
Probe-derived health, history, trends, and incidents — never hand-set.
RPC
One read-only JSON-RPC URL for Bittensor — health-aware load balancing, failover, and abuse controls.
GraphQL
Shape one request across the registry — a subnet with health, surfaces, endpoints, and economics.
Webhooks
Subscribe to the registry's publish change feed with HMAC-signed, at-least-once delivery.
Feeds
Registry changes, incidents, and coverage gaps as RSS 2.0, Atom 1.0, or JSON Feed.
Search & AI
Keyword search, vector search, and grounded question-answering over the registry.
Reference & catalog
Subnet catalog
129 curated subnets, generated from the registry overlays — focus areas, links, and coverage at a glance.
API reference
Every endpoint, request/response schema, and a live try-it client — generated from the published OpenAPI spec.
Protocol
How Bittensor itself works, independent of this API.
Understanding stake-weight
The two-component stake_weight formula, and why root TAO counts differently than subnet Alpha.
Registration and validator permits
What it costs to get a UID on a subnet, and why that's different from holding a validator permit.
Weight-setting, tempos, and rewards
What validators submit, when a subnet's consensus run happens, and how incentive/dividends get computed.
Proxy accounts
How pallet_proxy lets an account delegate scoped, revocable authority without a multisig ceremony.
Root stake and childkey delegation
How set_children lets a parent hotkey's root-network stake back child hotkeys across many subnets.
