Get block headers (max: 20) for minHeight <= height <= maxHeight. If maxHeight does not yet exist, blocks up to the current height will be returned. If minHeight does not exist (due to pruning), earliest existing height will be used.

At most 20 items will be returned. Block headers are returned in descending order (highest first).

Parameters

• minHeight - integer, minimum block height to return
• maxHeight - integer, maximum block height to return

Result

Block headers, returned in descending order (highest first).

Example

Request

curl <your-tendermint-endpoint>/blockchain?minHeight=1&maxHeight=5200792

Return
