The first dataless API for developers
One endpoint, one instruction — get structured JSON back instantly. No database setup, no predefined categories, no maintenance. Just describe what you need.
Free tier available. No credit card required.
How It Works
Describe What You Need
Send a plain-language instruction to our single endpoint. Tell us what data you want — vehicles, recipes, users, anything.
Optionally Set Rules
Create a category_id to save output schemas and formatting rules. Reuse them across requests for consistent structure.
Get Structured Data
Receive perfectly structured JSON responses instantly. AI-powered, vector-database backed, always consistent.
