It’s been a while since I first wrote an article about LLMs and Microservices. But the various discussions at the ExploreDDD conference - including a panel about the intersection of DDD and LLMs - inspired me to revisit the topic.

About Faramir
Faramir is a simple Python-based microservice that uses Langchain and OpenAI to validate and format phone numbers. You could, for example, use Faramir to make it easier for users to enter phone numbers in a web form.
Here’s an example of Faramir in action:
$ http POST localhost:8000/parse phoneNumber=5105551212
