Sudo Calls
Last updated
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'. ?limit (<=100) / ?offset (or ?cursor= for stable keyset paging) and a conjunctive filter set: ?block=, ?call_function=, ?success=true|false, ?block_start/?block_end (block range), ?from/?to (observed_at epoch-ms range). Pass ?format=csv to download the filtered rows as CSV. Computed live from the first-party extrinsics tier (#4310/2.2).
Query Parameters
Maximum number of rows to return in one page (at most 100). A larger value, or a non-positive one, is rejected with 400 invalid_query -- so a short page means the result set is exhausted, not that the server quietly capped you (#9916). Omitted, the server applies 50.
1 <= value <= 10050Number of rows to skip before the page begins. Correct only in combination with the page size the response actually returned -- prefer cursor for anything beyond the first few pages, since a row inserted mid-scan shifts every later offset.
0 <= value <= 10000000Opaque pagination token: pass back the next_cursor from the previous response verbatim. Its contents are not stable and must not be parsed or constructed. Stable across inserts, unlike a row offset.
Inclusive first block height of the range to read. Omit for an unbounded end. Must not be later than the range's upper bound.
0 <= valueFilter to calls of this extrinsic within the pallet, e.g. add_stake.
Value in
- "true"
- "false"
Inclusive first block height of the range to read. Omit for an unbounded end. Must not be later than the range's upper bound.
0 <= valueInclusive last block height of the range to read. Omit for an unbounded end. Must not be earlier than the range's lower bound.
0 <= valueInclusive first observed_at bound, as epoch MILLISECONDS -- not a block height (use block_start/block_end for that). Omit for an unbounded end. Must not be later than the range's upper bound.
0 <= valueInclusive last observed_at bound, as epoch MILLISECONDS -- not a block height (use block_start/block_end for that). Omit for an unbounded end. Must not be earlier than the range's lower bound.
0 <= valueResponse format override. Use csv to download the route rows as text/csv; json keeps the default response envelope.
"json"Value in
- "json"
- "csv"
