## Signed block by height `GET /v1/proofs/block/height/{height}` The node's block at a Stacks height (`/v3/blocks/height/{height}`), same bytes as the by-id route. Near the tip the block at a height can change, so this is short-cached; prefer the by-id route once you know the id. Free and keyless: never metered, no account needed. Hosted limits: 10 requests per second per IP (1 for witnesses), or 20 (2) per account with a key. Bytes are passed through unchanged; verify them, do not trust them. ### Path parameters | Name | Type | Description | | --- | --- | --- | | `height` | integer, required | Stacks block height. | ### Responses - `200` The block bytes. - `400` A path or query parameter is malformed (`VALIDATION_ERROR`): hashes must be exact-length hex, heights non-negative integers - `401` This bind requires the instance token, and it was missing or wrong - `404` The node has no block at that height - `429` Rate limited; retry after `Retry-After` seconds - `502` The node or proof sidecar could not be reached, or answered with an unexpected status (`PROOF_SOURCE_ERROR`) ### Example ```bash curl https://api.secondlayer.tools/v1/proofs/block/height/9048502 \ -H "Authorization: Bearer $SECONDLAYER_API_KEY" ```
