Upload documents, ask questions, and get answers that are checked against your sources before they reach your users.\n\n## What makes it different\n\nEvery response includes a **trust score** (0.0 to 1.0) and a **verdict** (verified / rejected / weak). Wrong answers are blocked, not served.\n\n## Core features\n\n| Feature | Endpoint | Speed |\n| --- | --- | --- |\n| **Guard** — hallucination firewall | `POST /v1/fact-check` | <1ms (lexical) |\n| **RAG** — verified document Q&A | `POST /v1/query` | \\~1s |\n| **Tasks** — async verified execution | `POST /v1/tasks` | async |\n| **Agents** — deploy verified AI agents | `POST /v1/agents` | async |\n| **Chat** — OpenAI-compatible | `POST /v1/chat/completions` | \\~2s |\n\n## Authentication\n\n**Option 1 — RapidAPI** (recommended):  \nGet a free API key (300 req/month) at [rapidapi.com/binnewzzin/api/smart-rag-api](https://rapidapi.com/binnewzzin/api/smart-rag-api). Pass `X-RapidAPI-Key` header.\n\n**Option 2 — Direct API key**:  \nPass `Authorization: {{vault:bearer-token}}` header.\n\n## SDKs\n\n- Python: `pip install wauldo`\n    \n- TypeScript: `npm install wauldo`\n    \n- Rust: `cargo add wauldo`\n    \n\n## Links\n\n- [Live demo](https://wauldo.com/demo)\n    \n- [Documentation](https://wauldo.com/docs)\n    \n- [Leaderboard](https://wauldo.com/leaderboard) — 6-framework RAG benchmark\n    \n- [Trust Score tool](https://wauldo.com/tools/trust-score)","schema":"https://schema.getpostman.com/json/collection/v2.0.0/collection.json","isPublicCollection":true,"owner":"53502945","team":14559199,"collectionId":"1936d71a-c3c1-47b9-8b90-dbcebc94ef6d","publishedId":"2sBXitDTBS","public":true,"publicUrl":"https://documenter-api.postman.tech/view/53502945/2sBXitDTBS","privateUrl":"https://go.postman.co/documentation/53502945-1936d71a-c3c1-47b9-8b90-dbcebc94ef6d","customColor":{"top-bar":"FFFFFF","right-sidebar":"303030","highlight":"FF6C37"},"documentationLayout":"classic-double-column","customisation":{"metaTags":[{"name":"description","value":"Hallucination firewall for LLM outputs.
