Audit-grade fact-checking API that runs claims through an eight-model, five-stage adversarial pipeline and returns a cited verdict.

Five-Stage Adversarial Pipeline: Eight models across five stages gather evidence, argue the opposing side, and pass through three independent reviewers before a verdict is issued.
Multi-Vendor Independence: Verdicts come from LLMs across several vendors rather than one provider, so a single model's blind spot cannot decide the outcome.
Full Citation Trail: Every verdict ships with the real sources it rests on and the reasoning shown, so a human can audit why the answer came out the way it did.
Depth Ladder of Primitives: /extract, /assess, /verify and /ask let you trade latency against rigor — a fast multi-model check for live UX, the full pipeline for anything that will be published.
Claim Extraction from Free Text: /extract pulls the individually verifiable claims out of any document or model output so each can be checked separately.
Grounded Follow-Up Q&A: /ask answers questions about a completed verification using only that verification's evidence, keeping the conversation anchored to sources.
Drop-In Integrations: OpenAPI 3.1 with Python and TypeScript SDKs plus a CLI, and ready-made hooks for Claude, Cursor, n8n and Zapier.
Public Workbench and Bookmarklet: Paste a statement, link or question and get a sourced verdict without writing code, including a bookmarklet for checking claims while browsing.

Runtime Output Verification: Check what your LLM feature just produced against real sources before it reaches a user, asynchronously or inline.
Pre-Release CI Gates: Run generated content, docs or marketing copy through /verify in CI so unsupported claims fail the build.
Incident Triage: Verify claims circulating during a live incident and get a verdict with sources instead of a confident guess.
Editorial and Newsroom Checking: Extract the checkable claims from a draft and get each one scored with citations before publication.
Compliance and Risk Review: Produce an auditable trail showing what was verified, against which sources, for regulated or high-liability content.
Agent Tool Use: Give a Claude, Cursor or n8n agent a verification tool so it can confirm facts mid-workflow rather than asserting them.
