Instructions

1. Identify the topic(s) from the user's question
2. Fetch only the relevant URL(s) using WebFetch - do NOT fetch all docs
3. Extract the specific information needed to answer the question
4. Cite the source when providing the answer

Examples

User asks about order types or placing orders:

• Fetch: Exchange endpoint URL

User asks about WebSocket subscriptions:

• Fetch: WebSocket subscriptions URL (and possibly general WebSocket URL if needed)

User asks about getting market data:

• Fetch: Info endpoint - perpetuals (for perps) or Info endpoint - spot (for spot)

User asks about authentication or signing:

• Fetch: Signing URL

Important

• Only fetch what's needed - don't fetch multiple docs unless the question spans topics
• If the question is ambiguous, start with the most likely doc and fetch more if needed
• Always prefer official documentation over assumptions
