Picking the right API Paradigm

There are not many people who I trust on the subject of API design like I do Phil Sturgeon. He has been a prominent speaker both online and at numerous conferences, covering a variety of problems, solutions, and approaches in the API design domain.

In one of his recent blog posts, he shared a diagram (see above) which provides a clear illustration on which API paradigm – REST, GraphQL, or RPC – one should pick for a web application, based on a variety of criteria.

I think this is probably the simplest of all the explanations I’ve seen around.

12 Best API Monitoring Tools for Your Business

12 Best API Monitoring Tools for Your Business” lists a bunch of services that are useful for the monitoring of your API.  Read the whole thing for more details.  Here’s the list of the services covered:

Crell/ApiProblem – a simple implementation of the api-problem specification


I’ve been working with REST/RESTful APIs for a while now.  They are usually a lot better than the SOAP or XML-RPC stuff we had before.  But they are also not perfect.  Error handling and reporting is a common area between many implementations that needs more attention and consistency.  Turns out, there is, I’ve just somehow never heard of it – RFC7807 defines “Problem Details for HTTP APIs”.

I’ll need to look more into this and see if and how it is better than a variety of things I’m using now.  Gladly, there is even a PHP library to help with that – Crell/ApiProblem:

This library provides a simple and straightforward implementation of the IETF Problem Details for HTTP APIs, RFC 7807.

RFC 7807 is a simple specification for formatting error responses from RESTful APIs on the web. This library provides a simple and convenient way to interact with that specification. It supports generating and parsing RFC 7807 messages, in both JSON and XML variants.

CurlMail – easy way to send emails with cUrl


I am a big fan of small and simple yet practically interesting ideas, like this one.  CurlMail is a super easy API service that allows one to send emails from the command line, using nothing but curl, or a similar HTTP client.

It’d be extra cool if it there was a GitHub link to it too.  But even if it’s not openly available, one could use the service for emails which are not sensitive and implement something similar from scratch in a few minutes for private use.

Google Trends for REST, GraphQL and RPC


Here’s an interesting look at Google Trends for REST API, RPC, and GraphQL.  There’s also a link to the actual Google Trends, in case you want to play with it.  For example, here’s how it looks with the addition of the SOAP (as a protocol though, rather than search term which is way too generic):
