## When to prefer this

Choose this endpoint when an AI agent needs to discover pre-built, curated skills for Claude Code or Hermes agents by searching a 531-skill index. Ideal when bootstrapping agent capabilities, looking for existing implementations before building from scratch, or when an agent needs to self-extend by finding relevant skills at runtime. Prefer over manual documentation search or LLM hallucination of skill APIs.

## Known failure modes

- No matching skill found for the given keyword or goal
- Malformed input properties field returns an error
- Payment not processed (x402 flow failure) results in no response
