MBV offers unlimited validation attempts without harming the consumer’s credit and is available at two levels of verification. Basic verification is available for batch processing or via a flexible API and does not require consumer authorization of participation with the bank. Data is usually returned within 24 hours of submission.

Lura
Lura
An extendable, simple and stateless high-performance API Gateway framework designed for both cloud-native and on-prem setups. Consumers of REST API content (especially in microservices) often query backend services that weren’t coded for the UI implementation. This is of course a good practice, but the UI consumers need to do implementations that suffer a lot of complexity and burden with the sizes of their microservices responses. Lura is an API Gateway builder and proxy generator that sits between the client and all the source servers, adding a new layer that removes all the complexity to the clients, providing them only the information that the UI needs. Lura acts as an aggregator of many sources into single endpoints and allows you to group, wrap, transform and shrink responses. Additionally, it supports a myriad of middlewares and plugins that allow you to extend the functionality, such as adding Oauth authorization or security layers. -

With logging, mini-documentation, Redis-powered acceleration, and a marketplace of over 40 integrations, NoCodeAPI eliminates server maintenance, streamlines API workflows, and empowers front-end developers to access third-party data directly and securely.Starting Price: $12 per month -

Apache Knox
Apache Software Foundation
The Knox API Gateway is designed as a reverse proxy with consideration for pluggability in the areas of policy enforcement, through providers and the backend services for which it proxies requests. Policy enforcement ranges from authentication/federation, authorization, audit, dispatch, hostmapping and content rewrite rules. Policy is enforced through a chain of providers that are defined within the topology deployment descriptor for each Apache Hadoop cluster gated by Knox. The cluster definition is also defined within the topology deployment descriptor and provides the Knox Gateway with the layout of the cluster for purposes of routing and translation between user facing URLs and cluster internals. Each Apache Hadoop cluster that is protected by Knox has its set of REST APIs represented by a single cluster specific application context path. This allows the Knox Gateway to both protect multiple clusters and present the REST API consumer with a single endpoint. -

Express Gateway
Express Gateway
Developing monolithic applications doesn’t work. Monolithic applications are being broken down into microservices. These microservices expose the application as set of APIs that can be consumed by anyone. Microservices and APIs is an architectural style that’s grabbing a lot of attention due an emphasis on sustainable development. If you’ve used Node.js, you’ve almost certainly come across Express.js. Express.js (Express) remains one of the largest, most widely adopted, open source projects in the world. Simplicity means that, as a minimalist, general purpose, framework that is familiar to every Node developer out there you can get started rapidly and continue that velocity throughout the API Development Lifecycle. We believe that an Express based API Gateway will be a powerful enabler for developers to sustainably build better, faster and more scalable applications. -
