## About this Actor

This example demonstrates how to use [USFWS Wetlands Proximity Screener - Section 404 Site Risk API](https://apify.com/malonestar/fws-wetlands-proximity-screener) with a specific input configuration. Visit the [Actor detail page](https://apify.com/malonestar/fws-wetlands-proximity-screener) to learn more, explore other use cases, and run it yourself.


## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
This Task's input is already configured above — use it as-is rather than inventing a new one.

- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
