Daily API RoundUp: Voltaire, CloudReq, Blend, TokenD, Squarelink

Every day, the ProgrammableWeb team is busy, updating its three primary directories for APIs, clients (language-specific libraries or SDKs for consuming or providing APIs), and source code samples. If you have new APIs, clients, or Source Code examples to add to ProgrammableWeb's directories, we offer forms (APIs, Clients, Source Code) for submitting them to our API research team. If there's a listing in one of our directories that you'd like to claim as the owner, please contact us at editor@programmableweb.com.

Eleven APIs have been added to the ProgrammableWeb directory in categories including Internet of Things, Payments and Crowdsourcing. Highlights include an API that returns localized information such as city, currency, language and Risk Assessment Data. Here's a rundown of the latest additions.


Blend is a technology provider for brokers and loan teams. Blend offers tools that shorten loan cycles, and integrates intelligent conditioning which automatically requests financial data such as bank statements, business license, and credit checks. Current wholesale lenders can extend their brand digitally and improve efficiency. The Blend API is accessible indirectly with the provided Go SDK, and is listed under the Financial category. See ProgrammableWeb's complete list of Financial APIs.

Squarelink is an access tool for blockchain applications that allows users to securely recover private keys. The Squarelink API provides a way for users to access accounts and sign transactions upon user permission. Squarelink's API allows developers to interact with Squarelink user accounts with methods for wallet information, personal information, and transaction data. The Squarelink OAuth API enables user authenitcation and allows user permitted account access. Squarelink APIs are listed under the Authentication category.

ipapi from APILAYER offers IP address-to-geolocation services. The ipapi API can enable applications to determine data based on user IP addresses including continent, country, city, ZIP code, coordinates, geoname ID, capital, languages, flags, calling code, EU membership, time zone, currency, ASN, ISP, and Risk Assessment Data. ipapi is filed under our Localization category. See ProgrammableWeb's complete list of Localization APIs.

ThingSpace is an Internet of Things Platform from Verizon. We have recently added three more APIs for integrating with the platform. Verizon ThingSpace SMS API lets applications send information to users phones, about devices or sensor readings. It can be useful to send time critical SMS alerts about gas leakage, smoke, fires, power outages, low-inventory warnings and more. Verizon ThingSpace Device Location API rovides a way to find the location of IoT devices in an account. It is useful to track assets, plan routes, estimate arrival time and more. And the Verizon ThingSpace MapQuest Static Map API enables users to create, configure, and return a map image of almost any size through a simple HTTP request.
