We manually looked through thousands of Social apis to find the best. Here is a list of the most popular and cheapest Social APIs.

 The Flickr API is available for non-commercial use by outside developers. Commercial use is possible by prior arrangement.

What is Flickr?

Flickr is almost certainly the best online photo management and sharing application in the world. On Flickr, members upload photos, share them securely, supplement their photos with metadata like license information, geo-location, people, tags, etc., and interact with their family, friends, contacts or anyone in the community. Practically all the features on Flickr's various platforms -- web, mobile and desktop -- are accompanied by a longstanding API program. Since 2005, developers have collaborated on top of Flickr's APIs to build fun, creative, and gorgeous experiences around photos that extend beyond Flickr.

The Flickr API

With over 5 billion photos (many with valuable metadata such as tags, geolocation, and Exif data), the Flickr community creates wonderfully rich data. The Flickr API is how you can access that data. In fact, almost all the functionality that runs flickr.com is available through the API. And the API is completely free to use, as a service to our members as well as developers and other integrators, so they can create even more ways to interact with photos beyond flickr.com.

Getting the most out of the Flickr API

We encourage all sorts of integrations, such as features and products that:

- Help people make their photos available to people who matter to them
- Enable new ways of organizing photos and videos
- Are fun!

The Graph API is the primary way to get data into and out of the Facebook platform.

**Graph API**

The Graph API is the primary way to get data into and out of the Facebook platform. It's an HTTP-based API that apps can use to programmatically query data, post new stories, manage ads, upload photos, and perform a wide variety of other tasks.

The Graph API is named after the idea of a "social graph" — a representation of the information on Facebook. It's composed of nodes, edges, and fields. Typically you use nodes to get data about a specific object, use edges to get collections of objects on a single object, and use fields to get data about a single object or each object in a collection. Throughout our documentation, we may refer to both a node and edge as an "endpoint". For example, "send a GET request to the User endpoint".

Here are some of the key features of Graph API:

- **Batch Requests**
The Facebook Graph API Batch Requests guide explains how to pass instructions for several operations in a single HTTP request and specify dependencies between related operations.

- **Field Expansion**
The Facebook Graph API Field Expansion guide explains more advanced API requests including field expansion, limiting results, nested requests, and pagination.

- **Upload Files**
The Facebook Graph API Upload Files guide explains how to upload files and use the uploaded media in other API calls.
