## REST API

Base URL: `https://skillsmp.com`

SkillsMP provides a free REST API for programmatic access. Keyword search works without authentication (just call the endpoint); AI semantic search requires an API key.

Full interactive documentation with code examples: https://skillsmp.com/docs/api

### Quick Start

Anonymous (no setup needed):
```
curl "https://skillsmp.com/api/v1/skills/search?q=playwright"
```

Authenticated (higher limits + AI search):
```
curl "https://skillsmp.com/api/v1/skills/search?q=playwright" \
  -H "Authorization: Bearer sk_live_your_api_key"
```

### Rate Limits

| Tier | Daily | Per-Minute | Available Endpoints |
|------|-------|------------|---------------------|
| Anonymous (no API key) | 50 | 10 | Keyword Search |
| Authenticated (API key) | 500 | 30 | Keyword Search, AI Search |

Get your free API key at https://skillsmp.com/docs/api (requires login). All quotas reset at midnight UTC.

Rate limit headers are included in every response:
- `X-RateLimit-Daily-Limit` — your daily request limit
- `X-RateLimit-Daily-Remaining` — remaining requests for today
- `X-RateLimit-Minute-Limit` — per-minute burst limit (search endpoint)
- `X-RateLimit-Minute-Remaining` — remaining requests this minute

### Authentication

Pass your API key via the Authorization header:
```
Authorization: Bearer sk_live_your_api_key
```

### Agent Authentication

AI agents (Claude, ChatGPT, autonomous pipelines) authenticate with long-lived API keys — no OAuth or user interaction needed at runtime.

1. A human owner signs in at https://skillsmp.com/auth/login and generates an API key from the Developer Portal.
2. Store the key in your agent's secret manager (env var, vault, KMS). Never put it in client-side code or URLs.
3. Send `Authorization: Bearer <key>` on every request.
4. On HTTP 429, read `X-RateLimit-Minute-Remaining` / `X-RateLimit-Daily-Remaining`, back off, and retry.
5. Set a descriptive `User-Agent` (e.g. `SkillsMPClient/1.0 (+https://your-agent.example)`) so we can reach you on issues.
6. Prefer MCP (https://skillsmp.com/mcp) over hand-rolled REST for tool-calling agents.

### Webhooks

SkillsMP does not currently emit outbound webhooks. Agents that need to track the catalog should poll:

- New/updated skills: `GET /api/v1/skills/search?q=*&sortBy=recent&limit=50` (hourly cadence matches our ETL refresh)
- Timeline trends: `GET /api/timeline?granularity=daily&limit=30`
- MCP push-style: call `search_skills` on a timer and stream into context — no inbound endpoint required

Outbound webhooks for new-skill and update events are on the roadmap. Details: https://skillsmp.com/developers#webhooks
