RC get extrinsic by index

GET

https://ksm-playbook.nownodes.io/v1/rc/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 relay chain block by its index. 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.
