Block Extrinsics
Last updated
Fetch the extrinsics in one block (by numeric block_number or 0x block_hash), in natural order; ?limit (<=100) / ?offset. Computed live from the first-party extrinsics tier (#1845); 200 with extrinsics:[] when cold/unknown.
Path Parameters
A block reference: either a decimal block number or a 0x-prefixed block hash.
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 <= 10000000Response format override. Use csv to download the route rows as text/csv; json keeps the default response envelope.
