Wauldo API — Verified AI Answers from Your Documents.

Turn your documents into a trusted AI knowledge base.\nUpload any document, ask any question, and get answers strictly grounded in your data — with source citations, confidence scoring, and built-in verification.

NEW — Native PDF & DOCX Upload\nPOST /v1/upload-file\nUpload PDF and DOCX files directly. Text extracted server-side with quality scoring.

Document quality score (0-1) with label (high/medium/low)
Structure-aware PDF chunking (sections, pages, paragraphs)
Production hardened: ZIP bomb protection, concurrency limits, timeout
Also supports: TXT, MD, JSON, YAML, CSV, code files, PNG, JPG, WebP, GIF

What You Get:

Grounded answers — no unsupported claims
Source citations for every response
Confidence score per answer
All-in-one pipeline — retrieval, generation, and verification in a single API

NEW — Citation Verify API\nPOST /v1/verify\nEnsure AI responses properly cite their sources.

Detects uncited sentences
Flags phantom citations (non-existent references)
Calculates citation coverage ratio
Supports formats: [Source: X], [1], (Ref: X), ^N
No LLM required — <1ms latency

NEW — Semantic Fact-Check\nPOST /v1/fact-check\nVerify any claim against source context with three precision levels:

Lexical — <1ms, word overlap + contradiction detection
Hybrid — token matching + semantic similarity (BGE)
Semantic — full embeddings, detects paraphrases and synonyms

Returns: Verdict (verified/weak/rejected), Action (allow/review/block), Reason per claim.\nDetects: contradictions, numerical mismatches, negations, missing evidence, paraphrases.

The Problem:\nLLMs often hallucinate unsupported facts, miss critical context, fail to cite reliable sources, and produce inconsistent answers. Without verification, you can't trust outputs at scale.

The Solution:\nWauldo combines retrieval from your documents, context-aware answer generation, source-based grounding, claim-level fact-checking (3 modes), and citation validation with phantom detection. If evidence is weak or missing, the API reflects it instead of guessing.

Why It Matters:

Build AI features you can trust
0% hallucination verified across multiple LLMs
<100ms fast-path answers when confidence is high
82% accuracy on a 61-task evaluation suite
SDKs: Python, TypeScript, Rust
