Chain status

GET https://api.bloklake.com/v1/chains/{chain}/status

No key needed, not billed.

Example

curl https://api.bloklake.com/v1/chains/eth/status

{
  "chain_id": 1,
  "first_block": 0,
  "archive_height": 21034551,
  "finalized_block": 21034480
}

integer

The chain’s id.

integer | null

The lowest block you can query.

integer | null

The newest block you can query: the chain head as Bloklake sees it.

integer | null

The newest block that can no longer change. Blocks above it, up to archive_height, can still be replaced by a reorg.

All three block numbers are null only if the chain has no data yet.

Decide the range of a backfill: from first_block (or later) to archive_height, or to finalized_block if you only want final data.
Monitoring: how far the chain’s data is from the real chain head.

Every query response carries archive_height and finalized_block too, so a running client rarely needs this endpoint.
