    • Private API Introduction

    The Fairlay Private API allows you to POST requests (creating/changing markets and orders, transfering funds, etc.), costs 0.1mBTC per 100.000 requests, see below on how to create your developer API account.

    This is the low level documentation, if you need a working sample or are more comfortable reading code rather than specifications, head over to .NET API Library or Python API Library

    Requisites

    1. An account registered at fairlay
    2. A 2048 bits PEM RSA Key pair. There are multiple types of tools to generate it for you. Tools SSL Example
    3. Create an API account in profile page at https://fairlay.com/developer/api/new/. Will be requested to provide your public key on form.

    Requests

    This is a sample GETBALANCE Request using default ACCOUNT ID 1:

    uiskPc9GqWAdUt1hJ+4VeuxyCNtbs0iY3kSbGQZ7HvwHkCe5H2n9UcX5v1Gl7Mb99XnhBiVzkne5bdkgmLdnlzzEBPLYnt8zwWHcqxXvIYiDpLQhsVfdkvyYwH1zgrUwAZu08VmY0ax34zxjXJdK68TVs9Y1m7akXkw5/NvIwXk=|635972931146604657|100012|1022|<ENDOFDATA>

    The response is usually JSON-encoded:

    rfV2ylPLbDbBKEy0yi71xZS/fZbyozd7+smpit1cR8ZeB0qo+stRDttTkCxqF0towkS0bf3lkg4amSbvka6K//QX/F1BHdFNqpkFXQHB9jh2eyR2WgXblKeGRbgw+mma+1P/kKNBtf3qhOUiqOgzONwlTEusiLzqHil6HLTQTKY=|635972681796848020|1066|{"PrivReservedFunds":334.049,"MaxFunds":0.0,"PrivUsedFunds":207.12,"AvailableFunds":126.946}

    If there is an error, the server returns an error message starting with XError: for general errors or YError: if there was an error in a subtask of a bulk change order request.

    All requests should be made to this endpoint:

    31.172.83.53:18017

    You must sign messages with your RSA key and provide your signature with all requests:

    nonce|userID|requestID|requestData

    The signature shoud be digested RSA-SHA512 signature encoded in Base64.

    Requests must be send via TCP in the following format:

    signature|nonce|userid|requestID|requestData<ENDOFDATA>

    Every request must end with <ENDOFDATA>

    Remember to use (YOUR API ID*1000)+Request ID on requests. Example: If you create your API accont on Fairlay, site will set an ID to it, usually first API ID is 1. So a request to Get Orderbook with this account will be 1001.

    Public API Introduction

    This is a free service to scrape all markets on Fairlay. For all POST requests (creating/changing markets and orders) use the paid Private API.

    For more examples how this API should be used together with our paid API, please take a look at our sample clients in C# and Python.

    Please feel free to comment and make suggestions.

    Free Servers

    http://31.172.83.181:8080

    used by default for all Public API calls

    http://31.172.83.53:8080

    (is an alternate server with the same functionality, also used for all Private API calls)

    For examples on how to use each of the API calls presented here, see the C# Unit Tests.

    In all of the examples below you can call /free/(method) calls with /free0/ up to /free9/ to increase the given limits above, a simple way is to either rotate from 1 to 9 or just randomize the free call from 1 to 9.
