Runs the open-source hefesto-ai engine (`hefesto analyze --no-config`, free tier) on the files you send to the hosted analyzer and returns its findings: rule id, severity, file, line, message and the SARIF hefestoFingerprint/v1 fingerprint (format "sarif" adds the full SARIF 2.1.0 log). Provide files, or a single code snippet plus language. Covers Python, COBOL, the DevOps/IaC formats hefesto analyze routes, and TypeScript, JavaScript, Java, Go, Rust and C# through the multilang tree-sitter grammars (the first such request on a fresh server instance downloads the grammars and can take a few seconds longer). Limits: 20 files, 100 KB per file, 256 KB in total, 20 seconds, 10 requests per minute per IP on each server instance. No .hefesto.yaml is read. Files are deleted after the run; nothing is stored. For a whole repository, run `hefesto analyze .` locally.
