Get block extrinsic calls

Returns the calls for extrinsic in a block by block reference and 0-based extrinsic index.

get/blocks/{block_ref}/extrinsics/{extrinsic_index}/calls

  • URL: https://bridge-hub.polkadot.crystal.api.submerge.io/v1/blocks/{block_ref}/extrinsics/{extrinsic_index}/calls
  • Auth: none declared

Path parameters

block_refstring required

Block reference for the extrinsic. Either a block number (integer ≥ 0), or a block hash in hex (with or without 0x prefix, case-insensitive).

extrinsic_indexinteger required

0-based index for the extrinsic in the block.

Query parameters

pageinteger

Block call list page number to retrieve. 1-indexed.

page_sizeinteger

Number of block calls per page to be returned.

pallet_namestring

Filter blocks calls by pallet name. Case insensitive. Underscore (_) character is ignored.

call_namestring

Filter blocks calls by call name. Case insensitive. Underscore (_) character is ignored.

is_signedboolean

Whether to include only calls within signed/unsigned extrinsics.

include_argsboolean

Whether to include call arguments in the block calls in the response. Default is false. Setting this to true increases the response size considerably. Prefer to use the GET /call/{call_hash}/args endpoint per call instead.

Response

Paginated list of matching calls.
