Details

Called server-side by Page Builder Sandwich. The request is signed with the site's licensing install secret key: signature = hex(HMAC-SHA256(install_secret_key, "zinn-pbs-library/v1\n{product}\n{install_id}\n{license_id}\n{site_url}\n{timestamp}\n{nonce}")). The engine reads the install from the licensing vendor with the product's keys, recomputes the signature, and checks the licence (active, this product, a paid plan). A proof older than 5 minutes (proof_expired) or seen before (proof_replayed) is 401; a wrong signature or a lapsed licence 403 licence_refused; a free plan 403 pro_required; a vendor that cannot be reached 503 licence_unverifiable. The token is returned once and lives 30 days. Budget 30/hour per IP.
