Blocks API

Block listings, lookups by height or hash, and block-level statistics for both chains.

GET/api/v1/{chain}/blocks/QRL 2.0QRL (PoW)

Get Blocks

Cursor-paginated block list (live feed — newest first).

Pass cursor from the previous response to get older blocks. The cursor encodes the last block's height; the next page is WHERE height < cursor ordered by height DESC. No offset/page params — blocks are inserted at the head continuously and offset paging would skip or duplicate rows between page-clicks.

Query parameters

Name	Type	Required	Default	Description
cursor	string \| null	no	—	Opaque pagination token from a previous response's `next_cursor`. Omit to start at the chain head (newest). Do not decode/construct.
limit	integermin 1 · max 100	no	25	Items per page (1-100).
min_height	integer \| null	no	—	Filter: height >=
max_height	integer \| null	no	—	Filter: height <=
miner	string \| null	no	—	Filter: block proposer / miner address
min_gas_used	integer \| null	no	—	Filter: gas_used >=
time_from	integer \| null	no	—	Filter: timestamp >= Unix seconds
time_to	integer \| null	no	—	Filter: timestamp < Unix seconds
has_withdrawals	boolean \| null	no	—	qrl2 only: True=only blocks with withdrawals, False=only without

Get Block By Hash

Get a block by its hash. Mounted under /blocks/hash/{hash} (not /blocks/{hash}) to avoid ambiguity with the integer-height route below. Routes are matched in declaration order, so this specific path wins over the catch-all /{height} when the URL starts with hash/.
