# MaxMind Developer Portal

> Documentation for MaxMind's GeoIP and GeoLite IP intelligence databases and
> web services, and for the minFraud fraud detection web services.

Every documentation page has a Markdown version at the page URL followed by
`index.md`, for example
https://63cee7f8.dev-site-4ua.pages.dev/geoip/docs/web-services/responses/index.md. Every page listed
below, as one Markdown file, is at
[llms-full.txt](https://63cee7f8.dev-site-4ua.pages.dev/llms-full.txt).

The GeoIP web services are GeoIP Country, GeoIP City Plus, and GeoIP Insights.
The minFraud web services are minFraud Score, minFraud Insights, and minFraud
Factors. Each field in the API reference names the services that return it.
