Mock sample for your project: Flat API

Display & Video 360 API allows users to automate complex Display & Video 360 workflows, such as creating insertion orders and setting targeting options for individual line items.

MetaPub collects, normalizes and distributes publicly available program, episode, and piece metadata through the public radio system. Backed by ContentDepot and its data model, MetaPub allows producers to supply metadata through various methods:
MetaPub Agents that collect producer metadata by "crawling" existing public feeds (e.g. C24, BBC) or the producer's production system (e.g. ATC, ME, TED Radio Hour).
Manually enter metadata in the ContentDepot Portal on each program and episode.
Publish/push the metadata to the MetaPub upload API and execute an ingest job.
MetaPub then distributes this data to stations through an electronic program guide (EPG model)
for display on various listener devices such as smart phones, tablets, web streams, HD radios, RDBS enabled FM radios, and more. The EPG format is based on the RadioDNS specifications.
RadioDNS and MetaPub
The RadioDNS Service and Programme Information Specification (TS 102 818 v3.1.1) defines three primary documents: Service Information, Program Information, and Group Information. These documents, along with the core RadioDNS Hybrid Lookup for Radio Services Specification (TS 103 270 v1.2.1) define a system where an end listener device can dynamically discover program metadata and fetch the metadata via Internet Protocol (IP) requests. MetaPub's use of RadioDNS differs slightly in that MetaPub (a.k.a PRSS) acts as the "service provider" while the stations and related middleware act as the end devices. While this is not the primary use case of RadioDNS, the flexibility in the specification, service definitions, and DNS resolution allows this model to be easily represented.
This documentation gives a high level overview of how the RadioDNS specifications will be used by MetaPub, however it is strongly recommended that the related RadioDNS specifications be read for implementation details, definitions, and required XML schemas.
ContentDepot Drive
ContentDepot Drive (CD Drive) provides a private, per customer file storage solution similar to other cloud storage solutions such as Google Drive, Box, and Dropbox. The CD Drive is used to stage content uploads such as metadata files, images, or segment audio before associating the content with specific programs or episodes.
CD Drive content can be referenced using a URI by some operations such as synchronizing metadata. There are two possible CD Drive URI formats supported: ID and hierarchical path. The ID reference takes the form . More information about URIs can be found at Wikipedia.
Authentication
The API currently uses OAuth 2.0. Some operations require specific scopes to limit clients while the ContentDepot backend may also enforce existing user specific permissions.

Introduction
The SearchLy API provides similarity searching based on song lyrics.
Operations
The API allows for the /similarity/bysong operation, which allows clients to search the similarity for an existing song in the database. Also, the API has an additional /similarity/bycontent endpoint which allows clients to search similarity given a free String input through a JSON request body. Additional /song/search operation is available for searching songs given a query String.
Endpoint
The API endpoint for the SearchLy API v1 is as follows:
Motivation
This project was built in order to create an API for searching similarities based on song lyrics. There are a lot of songs in the industry and most of them are talking about the same topic. What I wanted to prove with SearchLy was to estimate how similar are two songs between them based on the meaning of their lyrics.
SearchLy is using a database of 100k songs from AZLyrics, using this scraper, which is being updated periodically. Then, using word2vec and NMSLIB, it was possible to create an index where you can search similarities using the k-nearest neighbors (KNN) algorithm.
> Note: I am currently using a micro-instance from DigitalOcean where the API is deployed, so you should expect a bad performance. However, if this API becomes popular I will deploy it in a bigger instance.

A data platform for customers to create, manage, share and query data.

The Flat API allows you to easily extend the abilities of the Flat Platform, with a wide range of use cases including the following:
Creating and importing new music scores using MusicXML, MIDI, Guitar Pro (GP3, GP4, GP5, GPX, GP), PowerTab, TuxGuitar and MuseScore files
Browsing, updating, copying, exporting the user's scores (for example in MP3, WAV or MIDI)
Managing educational resources with Flat for Education: creating & updating the organization accounts, the classes, rosters and assignments.
The Flat API is built on HTTP. Our API is RESTful It has predictable resource URLs. It returns HTTP response codes to indicate errors. It also accepts and returns JSON in the HTTP body.
The schema of this API follows the OpenAPI Initiative (OAI) specification, you can use and work with compatible Swagger tools.
This API features Cross-Origin Resource Sharing (CORS) implemented in compliance with W3C spec.
You can use your favorite HTTP/REST library for your programming language to use Flat's API. This specification and reference is available on Github.
