GraphQL
The GraphQL Foundation
GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools. Send a GraphQL query to your API and get exactly what you need, nothing more and nothing less. GraphQL queries always return predictable results. Apps using GraphQL are fast and stable because they control the data they get, not the server. GraphQL queries access not just the properties of one resource but also smoothly follow references between them. While typical REST APIs require loading from multiple URLs, GraphQL APIs get all the data your app needs in a single request. Apps using GraphQL can be quick even on slow mobile network connections. -

RecallGraph is a potential fit for scenarios where data is best represented as a network of vertices and edges (i.e., a graph) having the following characteristics: 1. Both vertices and edges can hold properties in the form of attribute/value pairs (equivalent to JSON objects). 2. Documents (vertices/edges) mutate within their lifespan (both in their individual attributes/values and in their relations with each other). 3. Past states of documents are as important as their present, necessitating retention and queryability of their change history.

Runscope
Runscope
An API Monitoring (Runscope) API test is a group of one or more HTTP requests executed sequentially to evaluate the uptime, performance and correctness of an API. For each step in the test, you can define Assertions to validate response data and Variables to extract data to be used in subsequent requests. A test Passes if all the assertions pass. A test Fails if any assertion fails, or another error is encountered, such as a network connection problem. Your customers shouldn’t be the ones telling you about downtime and breakages. Runscope supports the notification tools you already use, like PagerDuty, Slack, HipChat, email, webhooks and more. Proactively monitor service performance to quickly catch and debug API problems fast. Stay ahead of intermittent failures before they become major issues with the API Dashboard and daily API Performance Report. Verify that the structure and content of your API calls meets your expectations. Powerful and flexible assertions give you total control. -
