What this skill does

# mkts Market Data Skill

A complete financial toolkit for AI agents. Get market overviews, live quotes, historical OHLCV data, earnings calendars, and news from 8+ sources. Screen assets by price, volume, and market cap. Compare tickers side-by-side. Track portfolios with P&L, allocation, and benchmark performance. Log trade rationale in a journal. Manage watchlists. No API key needed for market data — register programmatically for higher limits.

**Base URL**: `https://mkts.io/api/v1`

**Auth**: No API key required for basic access (20 req/hour per IP). For higher limits, register for a free key and pass it via header: `-H "X-API-Key: $MKTS_API_KEY"`

### Register for an API Key (Optional)
Get a free API key programmatically for higher rate limits (100 req/hour):
```bash
curl -s -X POST -H "Content-Type: application/json" \
  -d '{"email":"[email protected]","name":"my-agent"}' \
  https://mkts.io/api/v1/register
```
Returns `{ "success": true, "data": { "apiKey": "mk_live_...", ... } }`. Save the key — it is shown only once. Max 3 keys per email.
