What is the AI Research Engine?

An open-source list of 100+ free research APIs plus a Claude skill for multi-agent queries across 18 clusters, skipping Google entirely.

How do I set up the deep-research skill?

Copy `skills/deep-research/` to `~/.claude/skills/`, invoke with `/deep-research "your query"`. Install missing MCPs as prompted.

Most 🟢 free curls, some 🔑 free keys, few 📦 installs. Zero paid defaults.
