The AI search engine for rare API documentation
APIVault autonomously discovers, indexes, and monetizes hard-to-find technical documentation — so developers find what they need and publishers get paid.
Built for finance, healthcare, and IT teams.
Everything you need to surface and sell rare documentation
From autonomous crawling to built-in billing, APIVault handles the full lifecycle — so you can focus on building, not operating.
AI-Powered Discovery
Continuous crawling and AI-driven indexing surfaces documentation that traditional search misses — including private APIs, internal references, and archived specs.
Smart Monetization
Subscription and usage-based billing built in. Set per-document pricing, monthly plans, or API call quotas — and let APIVault handle authentication and metering.
Advanced Retrieval
Vector embeddings and full-text hybrid search return contextually relevant results — not just keyword matches. Built on proven infrastructure that scales to millions of docs.
Developer-First APIs
First-class SDKs, OpenAPI specs, and webhook support. Integrate APIVault into your existing stack with predictable rate limits and 99.9% uptime SLA.
API Marketplace
Publishers list documentation in the APIVault marketplace — a discoverable catalog where developers search, preview, and subscribe to documentation packages.
Usage Analytics
Track which docs get the most traction, where users drop off, and which search queries convert. Actionable insights to improve your documentation over time.
