API: circl.lu:hashlookup-circl-api
Endpoint: /parents/{sha1}/{count}/{cursor}
Response format: application/json
Auth: none
Method: GET
Last Status: 200
Latency: 117ms

Description

Returns a list of package/container SHA1 hashes that contain the specified file. Use this to find which software distributions, archives, or packages include a specific file. Supports pagination via count and cursor parameters.

From spec: Return parent containers/packages that contain a given SHA1 hash. Used for finding which packages or archives contain a specific file. Pagination is supported via count and cursor parameters.

Usage Tips

- Input must be a valid 40-character hexadecimal SHA1 hash of a file - Use cursor from previous response for pagination - Returns up to 'count' results (max recommended: 100) - Total count returned to help with pagination planning

Parameters (3)

count (integer, path, required)

Number of results to return

Constraints: {'minimum': 1, 'maximum': 1000}

cursor (string, path, required)

Pagination cursor (starting value is 0)

sha1 (string, path, required)

Child SHA1 hash in hexadecimal format

Constraints: {'pattern': '^[a-fA-F0-9]{40}$'}
