Provide Suggestive Hint for Pluralized Endpoint Errors

[gitfrosh]

In our app insights, I’ve noticed that API users frequently use the plural form of our endpoints, such as /quotes instead of the correct singular form, /quote. This results in a 404 error with a response like:

{
    "success": false,
    "message": "Not found."
}

To enhance the developer experience, we could include a helpful hint in the error response. For instance, if a plural endpoint is requested, we could respond with a message suggesting the correct singular form. This would make it easier for users to identify and correct the issue without extensive troubleshooting.

{
    "success": false,
    "message": "Not found. Did you mean to use the singular version of the endpoint, `/quote`?"
}
