Get a block by height or hash.

GET

https://dgbbook.nownodes.io/api/v2/block/{blockId}

Authorizations

ApiKeyAuthApiKeyAuth

api-key string

NOWNodes API key passed in the api-key header.

Returns block information with paged transactions. When full transaction details are unavailable, the response can contain only transaction ids.

Blockbook follows the backend main chain. Height lookups always return the current main-chain block. Hash lookups can return a block from another fork only if the backend still keeps it.

Load estimate: Medium; grows mainly with block transaction count and requested page.

Parameters

Block height or block hash.

Response
