Market hours, free and keyless.
Trade Time knows when the world's stock exchanges are open — open/closed status, next open, holidays, and sessions for 30 exchanges, from their published trading calendars. Two ways to build on it: a REST API for your own code, and an MCP server for your AI agent. Same engine behind both, so they never disagree. No account, no API key.
REST API
For your code
Plain JSON over HTTPS at api.tradeti.me. Call it from a script, a server, or straight from a browser front-end.
- Is a market open right now? When does it next open?
- Holidays, early closes, session structure
- OpenAPI spec ·
?at=time-travel · open CORS
GET /v1/exchanges/nyse/status→ { "open": true, "status": "main_open" }

MCP
For your AI agent
8 read-only tools so Claude, Cursor, or any MCP client can know market hours instead of guessing. npx or a remote URL.
- "Is the LSE open right now?" — a lookup, not a hallucination
- Works with Claude Desktop, Claude Code, Cursor, VS Code…
- MIT-licensed · keyless · nothing to host
"Is the NYSE open right now?"→ is_market_open("nyse") → open ✓

The same live data behind both — this is GET /v1/status, right now:

Not sure which? If you're writing software, use the REST API. If you want your AI assistant to answer market-hours questions, add the MCP server. Both are free, keyless, and read-only.
Free today — not a promise forever. The API and MCP server are free and keyless in this early phase. As the service grows, its limits, terms, and pricing may change, and it's offered as-is with no guaranteed uptime. Build on it — just don't assume it stays free indefinitely.
