evm
​
fromBlock
integer<int64>
required

The block number to start fetching from (inclusive).

​

The block number to fetch up to (inclusive). Optional; if omitted, streams until dataset height or timeout.

​
parentBlockHash
string

Expected hash of the parent of the first requested block.

​
includeAllBlocks
boolean
default:false

If true, includes blocks with no matching data in the response.

​
fields
object

Field selector for data items to retrieve.

​
logs

Response

A stream of blocks in JSON lines format, optionally gzipped. Can be empty if the data query has a bounded range and all blocks in the range have been skipped. May include X-Sqd-Finalized-Head-Number and X-Sqd-Finalized-Head-Hash headers, indicating the latest finalized block that's on the same chain as the returned blocks.

​
header
