Hallucination Firewall
POST /v1/verify The hallucination firewall runs every applicable check in parallel and returns a single PASS/FLAG/BLOCK verdict with a tamper-evident certificate. For code it validates packages; for prose it checks URLs, DOI/arXiv citations, numeric contradictions, and can ground claims against supplied source docs.
Capabilities
- ✓ Package, URL, DOI/arXiv, and numeric-contradiction checks
- ✓ Optional NLI grounding against supplied source texts
- ✓ PASS / FLAG / BLOCK with per-claim evidence
- ✓ SHA-256 certificate for audit
Use cases
- → Final gate before accepting any LLM output
- → RAG answers grounded in documents
- → Research and report generation
