# Latest Finalized Block

`GET /finalized-head`

## Request

- Base URL: `https://portal.sqd.dev/datasets/bitcoin-mainnet`
- URL: `https://portal.sqd.dev/datasets/bitcoin-mainnet/finalized-head`
- Auth: none required
- TypeScript: <https://skmtc.dev/sqd/apis/sqd-portal-api-bitcoin-dataset-endpoints/docs/finalized-head/get.ts> (a function with typed inputs; its response is checked against the schema)

Returns the block number and hash of the highest finalized block available in the dataset, or null if no blocks are available. Useful mostly for diagnostics, as clients using /stream can get this info from the X-Sqd-Finalized-Head-Number and X-Sqd-Finalized-Head-Hash response headers.

## Response `200`

Highest finalized block information

- BlockHead, nullable
  - `number` integer: Block number of the highest available block.
  - `hash` string: ID (hash) of the highest available block.
