AI agent skills for API integration
Integration skills save you from re-explaining an API every session: endpoints, auth shape, pagination, rate limits, and the three fields that are documented wrong. The strongest ones encode the failure modes — what a 429 means for this particular service, which errors are retryable — because that is the knowledge that is expensive to rediscover. Check when the skill was last updated; an integration skill pinned to an API that has since moved is worse than none.

How to install a API integration skill
- Compare the skills. Read the API integration skills below — each page shows the full SKILL.md, its safety verdict, and the capabilities it declares.
- Install it. Run npx skillmds@latest add <owner>/<name>. The CLI writes the skill into every agent directory it detects, or use --agent to pin one.
- Use it. Restart your agent. It loads the skill on demand the next time you ask for something that matches — you do not have to name the skill.
What makes a good API integration skill?
Integration skills save you from re-explaining an API every session: endpoints, auth shape, pagination, rate limits, and the three fields that are documented wrong. The strongest ones encode the failure modes — what a 429 means for this particular service, which errors are retryable — because that is the knowledge that is expensive to rediscover. Check when the skill was last updated; an integration skill pinned to an API that has since moved is worse than none.
Every skill listed here is a plain SKILL.md file in the format Anthropic documents for Agent Skills, read unchanged by Cursor, OpenAI Codex and 60+ agents. Each passes a safety review before it is publicly listed; the verdict and declared capabilities are on every skill's page.
Frequently asked questions
What is an agent skill for API integration?
Integration skills save you from re-explaining an API every session: endpoints, auth shape, pagination, rate limits, and the three fields that are documented wrong. The strongest ones encode the failure modes — what a 429 means for this particular service, which errors are retryable — because that is the knowledge that is expensive to rediscover. Check when the skill was last updated; an integration skill pinned to an API that has since moved is worse than none.
Do integration skills include API keys?
They must not, and any skill containing a credential fails the safety review before it can be listed. A well-built one tells the agent which environment variable to read and leaves the value to you.
Which agents can use these API integration skills?
Any agent that reads SKILL.md files: Claude Code, Claude.ai, Cursor, OpenAI Codex, Windsurf, OpenCode and 60+ others. The format is not vendor-specific, so the same file works everywhere — each agent just keeps its skills in a different directory, listed at /agents.
Are these API integration skills free?
Yes. Searching, reading and installing skills on SkillMD is free and needs no account. Individual skills carry their own licence, shown on each skill's page.
