# Monitor UK late payers and get alerts on changes

**Use case:** 

Watches large UK companies with a late-payment score of 50+ and returns only what changed since your last run: new late payers, flags added or removed, days to pay moving, e-invoicing or register status changes. The first run saves a baseline at no charge. Schedule it weekly for a change feed.

## 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/battles_2026/uk-late-payer-signals.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`).
