Overview

To avoid ambiguity, we denote the smallest possible multiple of USDC (0.000001 USDC) as one uusdc, which stands for µUSDC (micro-USDC), and denote the smallest possible multiple of a contract (0.01 contract) as one ccontract (centicontract).User-facing USDC balances are specified as fixed-point strings (e.g. "1.2625" for USDC). Contract quantities in the API and SDK are specified as integer ccontracts strings (e.g. "1050" for 10.50 contracts at precision 2).
Retrieve orders for a user with flexible filtering and cursor-based pagination. This endpoint supports filtering by status, market, action, side, and date range, with server-side sorting and efficient pagination for large order histories.

​
Filtering by Status

The status parameter accepts:
  • pending - Orders waiting to be filled
  • filled - Fully executed orders
  • cancelled - Cancelled orders
  • closed - Convenience filter for both filled and cancelled orders (useful for order history)

​
Pagination

This endpoint uses cursor-based pagination for efficient traversal of large datasets:
  1. Make an initial request with your desired limit (default: 50, max: 200)
  2. Check pagination.hasMore to see if more results exist
  3. Use pagination.nextCursor in subsequent requests to fetch the next page
Cursors are opaque strings and should not be modified. They encode the position in the result set and are only valid for the same query parameters.

​
Example: Fetching Order History

# First page of closed orders, sorted by most recent
curl "https://api.bison.markets/kalshi/orders?userId=0x...&status=closed&sortBy=updatedAt&sortOrder=desc&limit=10"

# Response includes pagination info
# {
#   "orders": [...],
#   "pagination": {
#     "total": 47,
#     "hasMore": true,
#     "nextCursor": "eyJ0IjoxNzAyMzQ1Njc4OTAwLCJpZCI6ImFiYzEyMyJ9"
#   }
# }

# Fetch next page using cursor
curl "https://api.bison.markets/kalshi/orders?userId=0x...&status=closed&sortBy=updatedAt&sortOrder=desc&limit=10&cursor=eyJ0IjoxNzAyMzQ1Njc4OTAwLCJpZCI6ImFiYzEyMyJ9"

​
Example: Pending Orders

# Get all pending orders (typically a small set, no pagination needed)
curl "https://api.bison.markets/kalshi/orders?userId=0x...&status=pending"
