Wauldo API — Verified AI Answers from Your Documents.

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

NEW — Analytics & Insights
GET /v1/insights — token savings, cost reduction, usage distribution per API key
GET /v1/analytics — cache hit rate, latency percentiles, cost per hour
GET /v1/analytics/traffic — per-tenant monitoring (requests, success rate, P95)

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

Document quality score (0-1) with label (high/medium/low)
\n
Structure-aware PDF chunking (sections, pages, paragraphs)
\n
Production hardened: ZIP bomb protection, concurrency limits, timeout
\n
Also supports: TXT, MD, JSON, YAML, CSV, code files, PNG, JPG, WebP, GIF
\n
What You Get:
\n
Grounded answers — no unsupported claims
\n
Source citations for every response
\n
Confidence score per answer
\n
All-in-one pipeline — retrieval, generation, and verification in a single API
\n
Citation Verify API
POST /v1/verify
Ensure AI responses properly cite their sources.
\n
Detects uncited sentences
\n
Flags phantom citations (non-existent references)
\n
Calculates citation coverage ratio
\n
Supports formats: [Source: X], [1], (Ref: X), ^N
\n
No LLM required — <1ms latency
\n
Semantic Fact-Check
POST /v1/fact-check
Verify any claim against source context with three precision levels:
\n
Lexical — <1ms, word overlap + contradiction detection
\n
Hybrid — token matching + semantic similarity (BGE)
\n
Semantic — full embeddings, detects paraphrases and synonyms
\n
Returns: Verdict (verified/weak/rejected), Action (allow/review/block), Reason per claim.
Detects: contradictions, numerical mismatches, negations, missing evidence, paraphrases.
\n
The Problem:
LLMs 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.
\n
Why It Matters:
\n
The Solution:
Wauldo 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.
\n
Build AI features you can trust
\n
0% hallucination verified across multiple LLMs
\n
<100ms fast-path answers when confidence is high
\n
83% accuracy on a 61-task evaluation suite
\n
SDKs: Python, TypeScript, Rust
