Screendoor

Screendoor is a form-building service that allows users to drag and drop text boxes, checkboxes, and file upload fields in a WYSIWYG form editor. Users can collect responses over the web, mobile devices, and email. Drafts of unfinished forms are automatically saved so that respondents can come back to them later. Screendoor users can export their data whenever they like, and they can integrate their data into other applications using the API.

EnClout Pacer

The Pacer service provides online access to documents related to appellate, bankruptcy, civil, criminal and multi-district litigation in the United States. This API about public access to court electronic records provides an easy-to-use JSON/XML to the Pacer Case Locator. When developers visit the site, they will see demo data because they have not been logged in yet in the system. Once they create a Pacer account, developers will have admission to an API key. Support available in contact form.

Passwd.me

If developers have been looking for a different, yet strong password protection API, Passwd could be the ideal documentation for app creation. Three categories can be seen in the API site to classify password security: secure, super secure and insanely secure. Nowadays it is not enough to have the same access code for multiple sites, that is why a good combination of letters and numbers from 8 to 62 characters might work to prevent unwelcome access from hackers. The API features JSON and JSONP protocols with the parameters of name, type and values. Simple examples, and immediate support available for developers.

Clickslide Datadipity

Datadipity allows users to combine APIs from multiple sources into a ready-to-use JSON API which can be used with any Javascript Library. It also creates an XML API endpoint with the mashup for connecting to app servers. Datadipity can integrate any API into the system with a simple form based tool. Users have the ability to restructure APIs as they please, allowing them to unify multiple APIs into a standardized format. Mashups or restructured APIs can be published for others to see or kept private.

TalkBack

ThingSpeak facilitates the collection of data from sensors and actuators in connected devices, the Internet of Things. Sensors monitor devices or conditions, and actuators allow control over devices to change conditions. The TalkBack API takes data collection a step further and provides a channel for a user to give a connected device a command, or a series of queued commands.

Mammalian Adult Neurogenesis Gene Ontology

The Mammalian Neurogenesis Gene Ontology (MANGO) is a searchable database describing the key stages in the development of adult hippocampal neural stem cells. MANGO is exposed to developers through an API. The MANGO API accepts HTTP GET requests and returns HTML, XML, or text formatted files. Exposed fields include GeneID, PubMedID, cell stage, effect, evidence, species, type, and expression.

Rutgers

Rutgers, The State University of New Jersey, provides a collection of APIs that may be useful to students and others who live or work on campus. The Rutgers APIs can be used to retrieve information on university events, dining locations, sports game scores, campus buildings, facilities' hours of operation, and class schedules. These APIs retrieve data in a variety of formats and all use their own endpoints. (Information on using the Nextbus API in the Rutgers area is also provided, although it is not one of the University's own APIs.)

tny.im

tny.im is a service for shortening URLs that is powered by the YOURLS script. Users have the option of implementing a custom keyword to make shortened links easier to write manually and remember. tny.im offers a RESTful public API that allows developers to integrate the service with their own applications.

It allows users to get around censorship, blocks, and filtering, and it complies with EU directives on Data Protection and e-Privacy. Users are also provided with a new IP address. No actions taken while using the VPN are logged. The AirVPN API allows users to access and control their accounts programmatically via REST calls.
