# Which path is yours?

> Your own account, someone else's members, public data or referrals. One question picks the API, the credentials and the page to start from.

Ask one question: **is it your own account, or someone else's?**

| You want to | Path | Credentials |
| --- | --- | --- |
| Trade your own account: scripts, algos, market making, even for a firm | Member API | An API key from your STX account, signing each request |
| Act for other STX members, with their consent | Apps | OAuth: members approve your app on STX |
| Show or analyse public market data: odds, prices, depth, events | Market data | OAuth client credentials of your own |
| Send players to STX, with no code | Affiliates | Your affiliate links |
