Use it with your AI

SKILL.md is an Agent Skill. It tells your AI:

1. How to download the file, and when to download it again.
2. The data model: every key, its type and what it means, and every API with its number of plans.
3. How to query it, with DuckDB, jq or Python.

Your AI answers from the file on your computer and links each plan’s page and docs.
