# Monitor a DEX Pool's Price & Liquidity — DEX Screener

**Use case:** 

Live price, liquidity, volume and risk flags for a specific DEX pool given its pair address, e.g. the AERO/USDC pool on Base: price, 1h/24h change, liquidity, 24h volume, transaction counts, market cap and flags like sell_pressure or low_liquidity. For traders and funds tracking their own pools on a schedule. Replace pairAddresses with any pool from a dexscreener.com/<chain>/<pair> URL.

## About this Actor

This example demonstrates how to use [Dexscreener Scraper — DEX Prices, Liquidity, New Pairs, Boosts](https://apify.com/yadroo/dexscreener-tokens.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/yadroo/dexscreener-tokens.md) to learn more, explore other use cases, and run it yourself.


## 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/yadroo/dexscreener-tokens.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`).
