Raw data endpoints for Cardano

Raw block data

Returns raw block data from our cardano-explorer-webapi instance. See https://cardanodocs.com/technical/explorer/api for field descriptions (/api/blocks/summary/{hash} section), but mostly they are self-describing. Our API also allows to query by block id.

Endpoints:

https://api.blockchair.com/{:ada_chain}/raw/block/{:height}₀

https://api.blockchair.com/{:ada_chain}/raw/block/{:hash}₀

Where:

{:ada_chain} can be only cardano

{:height}ᵢ is the block height (integer value), also known as block id

{:hash}ᵢ is the block hash (regex: /^[0-9a-f]{64}$/i)

Possible options:

?transactions=true displays transaction data

Output:

data contains an associative array:

data.{:id}ᵢ.block — block data
