# Polymarket–Kalshi arbitrage pairs: 2%+ edge, $25k+ volume

**Use case:** 

Only matched market pairs where the fee-adjusted, risk-free edge is at least 2% and Polymarket 24h volume is $25,000 or more, so the opportunity is actually tradable: both prices, match score and net edge.

## Input

```json
{
  "minNetEdgePct": 2,
  "minPolyVolumeUsd": 25000,
  "maxPairs": 200

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/tactful_anvil/polymarket-kalshi-arbitrage-scanner.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
