API Access
Use these values to configure the external REST API in Vercel. The API lets external devices (home dashboards, scripts, etc.) fetch your portfolio and market data without signing in.

This is a randomly generated suggestion, not your live key.
The key that actually works is whatever you saved in
MARKETWATCH_API_KEYS in Vercel — use that same value on every device.
Regenerating here changes nothing on the server.
Verify a key at /ext/v1/status?api_key=… (look for your_key_valid: true).
REST API — external devices (all require X-Api-Key header):
GET /ext/v1/portfolio — positions with live prices & P&L (?range=)
GET /ext/v1/performance — day / week / month / since-purchase returns for the whole portfolio
GET /ext/v1/performance/{symbol} — same windows for a single holding, e.g. /ext/v1/performance/ERIC-B.ST
GET /ext/v1/watchlist — watchlist with live quotes (?range=)
GET /ext/v1/market — all tracked global instruments (?range=)
GET /ext/v1/brief — AI market brief (add ?force=true to refresh)
GET /ext/v1/portfolio/brief — AI analysis of your holdings
GET /ext/v1/news — latest market news
GET /ext/v1/calendar — upcoming FOMC / ECB / CPI events
GET /ext/v1/quote?symbol=AAPL — single symbol quote
GET /ext/v1/status — env-var config diagnostic (no auth required)
?range= accepts today (default), week, 3m, 6m, 1y — controls the change window for portfolio / watchlist / market.
MCP Tools — available in Claude (via Marketsight MCP server):
get_market_overview — live prices for all tracked instruments
