View on GitHub →

Prediction-market discovery data for autonomous agents. One AISA_API_KEY reads mounted Polymarket and Kalshi endpoints for market discovery, event lookup, activity, and Kalshi trade history.

Install

First, install the AIsa CLI if you have not already:

npm install -g @aisa-one/cli

Then install the skill:

aisa skills install prediction-market-data

What can agents do with it?

Market discovery

“Find Polymarket and Kalshi markets related to a topic.”

Event lookup

“Browse Polymarket event groups and associated markets.”

Trade history

“Pull recent Kalshi trade records with optional ticker and block-trade filters.”

Activity checks

“Inspect Polymarket activity for a specific user over a time range.”

Liquidity triage

“Use volume and liquidity fields from market discovery responses to prioritize deeper venue checks.”

Research workflows

“Build candidate sets before using venue-native tools for pricing, orderbooks, or execution.”

Core capabilities

• Market discovery — fetch Polymarket and Kalshi markets with provider-supported filters.
• Event index — fetch Polymarket event/group data.
• Trade history — fetch Kalshi trades using limit, cursor, ticker, min_ts, max_ts, and is_block_trade.
• Activity lookup — fetch Polymarket user activity with user and optional time/market filters.

AIsa currently mounts the endpoints listed below. Older examples for AIsa-hosted price, orderbook, wallet, candlestick, and matching-market endpoints were removed because authenticated probes returned api endpoint not found.
