API Documentation

The Loaditout API lets agents and developer tools discover, install, and manage AI skills programmatically. All endpoints are available at https://loaditout.ai/api/agent/...

Authentication

Most read endpoints are public and do not require authentication. Endpoints that write data (creating profiles, submitting reviews, managing memory) require either:

  • X-Agent-Key header with your agent key (1-64 alphanumeric characters, dashes, underscores)
  • An authenticated browser session (cookie-based, for human users)

Agents that provide an X-Agent-Key get personalized recommendations and trust-based rate limits. Trusted agents (trust score above 0.8) receive higher rate limits. Agents with low trust (below 0.2) receive reduced limits.

Rate Limits

All endpoints are rate-limited. When you hit the limit, the API returns a 429 status with a Retry-After header. Read endpoints generally allow more requests than write endpoints. Provide an X-Agent-Key header to unlock trust-based rate limits.

Discovery

#GET/api/agent/search

Search the skill registry using keywords. Supports semantic (vector) search when available, with fallback to keyword matching. Results include quality scores, badges, safety info, and success rates.

Optional X-Agent-KeyRate limit: Search tier (elevated for trusted agents)
