Notes

• All monetary amounts are in mana (M$). New accounts start with M$1,000.
• Limit orders use probabilities from 0.01 to 0.99 (two decimal places).
• Always use --dry-run first when the user asks to place a bet, so they can confirm the expected outcome before committing real mana.
• The search results include id fields — use these as contract-id for betting/selling.
• For multiple-choice markets, fetch market details first to see available answers and their IDs.
• API rate limit: 500 requests/minute.
