  x-api-evangelist-provenance: 'Harvested verbatim from cPanel''s developer portal on 2026-09-05 via the MCP tool get-full-api-description at https://api.docs.cpanel.net/mcp. ONE mechanical change was made before storage: example values containing PEM private-key or certificate blocks, and AWS-access-key-shaped example strings, were replaced with REDACTED_* placeholders so the file can be stored in a public git repository without tripping secret scanning. No path, operation, parameter, schema or description was altered, added or removed.'
