Everything you need to ship one explainer URL: the API reference, the shortest working upload flow, and agent integration notes for Claude Code, Cursor, Copilot, Codex, and similar tools.
Request format, response contract, upload safeguards, rate limits, and the validation path behind every published explainer.
Go from API key to public URL in three steps, with a copy-pasteable curl request and the exact response payload your tool should expect.
Wire the existing explainer skill into AI coding agents, or call the API directly when your tool only needs an authenticated upload target.
If your tool already has HTML output, you can skip the skill entirely and call the upload API directly.
