Get positions in markets that are active within a time window.

Overview

Returns positions from both Polymarket and Kalshi that have been active within the specified hours window. Useful for:

• Pre-resolution position review — see which positions may need attention soon
• Exit planning before market closes
• Avoiding surprise resolutions

Parameters

Param	Type	Default	Description
hours	integer	24	Time window in hours (1–168, i.e. up to 1 week)
venue	string	all	all, polymarket, or kalshi
limit	integer	50	Max results (1–200)
offset	integer	0	Pagination offset

Cross-venue by default. The venue parameter defaults to all, returning merged positions from both Polymarket and Kalshi sorted by soonest activity. Each position is tagged with a venue field.

Example

curl

curl -X GET "https://www.aionmarket.com/bvapi/markets/positions/expiring?hours=24&venue=all&limit=50" \
  -H "Authorization: Bearer YOUR_API_KEY"

Python SDK

from aion_sdk import AionMarketClient

client = AionMarketClient(api_key="YOUR_API_KEY")

# Default: 24h window, all venues
positions = client.get_positions_expiring()

# Custom: 48h window, Kalshi only
kalshi_positions = client.get_positions_expiring(hours=48, venue="kalshi", limit=20)
