Get extrinsic by index

GET

https://ksmassethub-playbook.nownodes.io/v1/blocks/{blockId}/extrinsics/{extrinsicIndex}

Authorizations

ApiKeyAuthApiKeyAuth

api-key string

NOWNodes API key passed in the api-key header.

Changed. The extrinsic at the requested on-chain index is now always returned. Before, if an earlier extrinsic in the block could not be decoded, the list shifted and a different extrinsic could be returned. If the requested extrinsic itself cannot be decoded, it is returned with a new decodeError object (index, reason, rawHex), without method and args, and with era as an empty object.

Returns a specific extrinsic from a block by its index within the block. If that entry could not be decoded it is still returned, with decodeError set, no method or args, and era as an empty object; its events, success and paysFee come from the block's events, and success is false when the block carried no outcome event for that index.
