Agent skill
A short markdown file that teaches an agent how to use this API: the calls, the plans, the limits and the errors.
https://greyhoundracingapi.com/skill.mdAdd it to an agent
Claude Code: save it as ~/.claude/skills/greyhoundracingapi/SKILL.md.
Terminal
mkdir -p ~/.claude/skills/greyhoundracingapi && curl -s https://greyhoundracingapi.com/skill.md -o ~/.claude/skills/greyhoundracingapi/SKILL.md
Claude: upload it as a skill in Settings, Capabilities.
Other agents: agents that read the skills index find it at /.well-known/agent-skills/index.json.
The manual
For the whole API in one file, hand a model manual.md. Both the skill and the manual are rebuilt from the registry, so they always match these pages.
