Compare Minecraft world prices for real locations with MapMC

Quick overview

This workflow collects up to 8 place names via an n8n form, looks them up with MapMC geocoding, requests a MapMC price quote for each bounding box, and returns an HTML results page that compares areas and USD prices, sorted with a total and any unpriced items.

How it works

1. Starts when you submit a list of places (one per line) through an n8n Form Trigger.
2. Cleans the input by trimming whitespace, removing duplicates, and limiting processing to the first 8 places while tracking how many were skipped.
3. Queries the MapMC geocode search endpoint for each place (with a small delay between requests) to find a matching location.
4. Selects the first geocoding result as the best match and extracts its bounding box, or records a not-found/lookup-failed reason.
5. Sends each bounding box to the MapMC price quote endpoint (also rate-limited) to get estimated area and price in USD.
6. Builds an HTML report that sorts priced results by cost, calculates a total, and lists any places that are too large/small or otherwise could not be priced.
7. Displays the HTML report as the form completion page.

Setup

1. Execute the workflow and enter up to 8 places (one per line) in the form, or publish the workflow to use its production form URL.
2. Ensure your n8n instance can reach https://mapmc.app over HTTPS, since the workflow calls the public MapMC geocode and price APIs.
3. No credentials or API keys are required.
