6 endpoints.

* [Extrinsic Detail](/docs/api-reference/extrinsics/extrinsic-detail) — `GET /api/v1/extrinsics/{hash}`\
  Fetch per-extrinsic detail by 0x extrinsic\_hash OR the composite \<block\_number>-\<extrinsic\_index> id (the guaranteed-present identifier, since the hash is best-effort/nullable).
* [Extrinsic Detail By Network](/docs/api-reference/extrinsics/extrinsic-detail-by-network) — `GET /api/v1/{network}/extrinsics/{hash}`\
  Network-scoped form of /api/v1/extrinsics/\{hash} — prefix the route with a network to choose which chain answers it.
* [Extrinsics Feed](/docs/api-reference/extrinsics/extrinsics-feed) — `GET /api/v1/extrinsics`\
  Fetch the recent-extrinsic feed (newest first) for the block explorer; ?limit (\<=100) / ?offset (or ?cursor= for stable keyset paging, #1851) and a conjunctive filter set (#1846): ?block=\<n>, ?signer=, ?call\_module=, ?call\_function=, ?call\_hash= (0x-prefixed 64-hex-char decoded call hash, requires ?call\_module= to keep the JSON scan scoped — matches a Multisig approval chain's linked calls, #4322), ?success=true|false, ?block\_start/?block\_end (block range), ?from/?to (observed\_at epoch-ms range).
* [Extrinsics Feed By Network](/docs/api-reference/extrinsics/extrinsics-feed-by-network) — `GET /api/v1/{network}/extrinsics`\
  Network-scoped form of /api/v1/extrinsics — prefix the route with a network to choose which chain answers it.
* [Governance Config Changes](/docs/api-reference/extrinsics/governance-config-changes) — `GET /api/v1/governance/config-changes`\
  Fetch subtensor's own root-origin hyperparameter/network-config change feed, newest first — the extrinsics feed hardcoded to call\_module='AdminUtils' (re-scoped from the original Council/Senate framing; subtensor has no such pallet).
* [Sudo Calls](/docs/api-reference/extrinsics/sudo-calls) — `GET /api/v1/sudo`\
  Fetch the root-origin (Sudo pallet) call table, newest first — subtensor has no Council/Senate, so this is the extrinsics feed hardcoded to call\_module='Sudo'.
