Pick a tier to start pulling first-hand official Taiwan market data — try it free, integrate as a developer, or use it inside paid chat.
Tier 1
Paste this to your AI:
Read https://twmarketdata.com/skill.md and connect to TW Market Data. 先用 2330 試一筆。Any agent can pull real data instantly with the five key-free tickers (2330 TSMC / 2317 Hon Hai / 2454 MediaTek / 0050 Yuanta Taiwan 50 / 2603 Evergreen).
Tier 2
Claude Code / Cursor / your own agent: get an API key from your account page, call the REST API, and pay by usage.
curl -H "X-API-Key: $TWMD_API_KEY" "https://api.twmarketdata.com/v2/datasets/twse-daily-price?symbol=2330"Open a dedicated key for each agent (see key safety), and never paste your primary key into a conversation.
Tier 3
The only supported way to pay for access inside Claude.ai / ChatGPT, and the most reliable path for tool calls: add the TW Market Data connector, authorize, and go.
If you paste the one-liner in Claude.ai but can't get paid data, the product isn't broken — consumer chat goes through this connector tier.
In short: free trial goes through the one-liner, developer integration goes through an API key, paid consumer chat goes through the connector.
