Is the API Credentials skill free?

Yes. The skill itself is free from oaustegard/claude-skills. SkillProof publishes the install command and an independent test verdict at no cost.

Does API Credentials work with Claude Code?

It is in our test queue — we run every skill on real work before issuing a verdict, and this one is scheduled.

How do I install API Credentials?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use API Credentials with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.
