Seems to me like you have an opportunity to develop a couple SDKs in your customers' favorite languages (probably python and typescript) and a simple "Get Started" template that could alleviate a lot of these requests. Show them the base case, let them figure out how to work with your api via an SDK instead of directly with an API and let the advanced users build their own SDKs in whatever language they prefer. Since its, as OP claims, a simple HTTP API, the SDK could be generated with OpenAPI client generation tools.
