URL content checksum verification
Written by Agorean from what the endpoint says about itself
Confirms a URL's exact bytes match a claimed SHA-256 checksum.
It verifies that the exact bytes served at a public URL match a claimed SHA-256 checksum, by independently re-fetching the URL twice. It is meant to confirm a download or artifact matches its published checksum. It handles bodies up to 3 MB, and a dynamic page that can't be verified comes back unverifiable rather than a guessed match.
WHEN TO USE THIS
When: I need to confirm a downloaded file matches its published checksum
For example: Send the URL and claimed sha256 hash to verify.
When: I need to know if a URL's content can even be verified
For example: Check for an unverifiable result before trusting a match.
When: I want to try it before paying
For example: Use your first 100 free checks with the X-Use-Free-Allowance header.
