Extrinsics

6 endpoints.

• 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 — 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 — 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 — 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 — 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 — 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'.
