Universal Data Refinery

🌟 Why Data Refinery?

In the emerging Agent Internet, AI models and autonomous agents (Claude, Cursor, OpenAI Agents, custom bots) starve for clean, structured, real-time, deterministic data. Raw web scraping is noisy, token-expensive, and prone to hallucinations.

The Universal Data Refinery transforms messy, fragmented web documentation, pricing pages, municipal codes, and release logs into strict, schema-validated JSON with automatic semantic diffing and sub-second edge retrieval.

🚀 Built-in Refined Domains

1. 📦 Developer Ecosystem & Breaking Changes

• Extracts: Affected symbols, removal vs deprecation status, signature changes, and exact code migration snippets.

• Solves: AI coding assistant hallucinations regarding outdated syntax and breaking SDK upgrades.

2. 💰 B2B SaaS, Cloud & API Pricing Matrices

• Extracts: Normalized monthly/annual pricing, included quotas, usage-based rates, hidden contract caveats, and overage fees.

• Solves: Autonomous procurement and cost-estimation calculations for AI agents.

3. 🏛️ Localized Regulatory & Compliance Intelligence

• Extracts: Municipal ordinances, short-term rental permits, zoning rules, mandatory deadlines, and penalties.

• Solves: Legal and business compliance research without manual human paralegal effort.

4. 🌐 Universal On-Demand Web Refinery

• Extracts: Feed any URL + custom prompt on the fly. Workers AI extracts strict JSON, validates against Zod, computes diffs, and saves to D1 SQL.
