- Production URLs use HMAC-SHA256 signatures; the playground says its inputs stay in the browser.
Field notes
The page exposes the request grammar in detail, including expiry and preset metadata alongside ordered image operations. Its playground can assemble URLs in the browser, but some listed operations—such as face-aware processing—depend on server-side models or configuration. The site says production signatures are HMAC-SHA256 and points users to a client library or CLI for signing.
