Frequently Asked Questions about the Lookio API

How does the Lookio API compare to building my own RAG pipeline?

Building a RAG (Retrieval-Augmented Generation) pipeline requires managing document chunking, embeddings, vector databases, and complex LLM orchestration. The Lookio API abstracts this entire infrastructure. You simply upload your files via the dashboard or API, and query the endpoint to receive highly accurate, sourced answers instantly.

What can I build with the Lookio API?

The Lookio API is designed for automation and integration. Popular use cases include routing automated customer support workflows in n8n, building dynamic RFP response systems, creating internal company knowledge portals, and enriching custom backend applications with proprietary data.

Can I use the Lookio API with no-code tools like n8n, Make, or Zapier?

Yes. The Lookio REST API is built for seamless integration with automation platforms. We provide straightforward JSON responses, making it easy to call a Lookio Assistant from n8n, Make (Integromat), Zapier, or any custom software stack.

How does Lookio prevent AI hallucinations?

Lookio enforces strict grounding. When you query an Assistant via the API, the system only synthesizes answers based on the specific documents (PDFs, URLs, text) attached to that Assistant. Every API response also includes source metadata, giving you complete traceability.

Which query mode should I use for my API workflows?

Lookio offers four distinct API query modes: Eco (best for cost-effective, large-scale batch processing), Flash (optimized for fast, real-time routine workflows), Europe (100% sovereign European processing using Mistral), and Deep (designed for complex, multi-step research tasks).

Is the Lookio API secure and GDPR compliant?

Absolutely. The Lookio platform and API are fully GDPR-compliant by design. Your data remains private, is encrypted at rest and in transit, and is never used to train public foundational models.
