API v2 Documentation

Overview

This document provides a resource to use Tokenomy API v2 that is available at https://api.tokenomy.com. The Tokenomy API v2 provides HTTP and WebSocket APIs.

Most of the API requires authentication, except for the market’s related HTTP API and public WebSocket.

In each APIs, we will provide an example using curl. The "…" in the JSON response example indicates the response has been truncated.

API v2 uses the HTTP status codes as an indication of success or error. A success response is represented by HTTP status code 200-226. An error response caused by the client (for example, invalid parameters) is represented by HTTP status codes 400-451, and an error caused by the server is represented by HTTP status code 500-511.

In API v2, all responses have a single format, encoded in JSON as,

{
    "code": <number>,
    "message": <string>,
    "name": <string>,
    "data": <JSON object | JSON array>
}

The code field contains an optional response status code, its value is equal to the HTTP status code. The message field contains additional information, it’s usually used for an error response. The name field contains the name of error message, for example ERR_INTERNAL for status code 500 internal server error. The data field contains a dynamic value, either as a JSON object or JSON array, as a response to a successful request.

Pair name

Pair name, or sometimes we write it as pair, is a combination of two assets separated by underscore character ("_"). The asset before underscore is called a coin asset and the asset after underscore is called a base asset. For example, a pair between Tokenomy (the coin asset) and Bitcoin (the base asset) is written as "ten_btc".

The information about valid pair names in Tokenomy platform can be viewed from the Market information public API.

Schemas

This section contains a list of common objects that are returned by HTTP or WebSocket APIs.

All of the schemas uses the JSON format with standard JavaScript types: number, string, boolean, and null. In this document we have additional types:

address: The address in network as string.
assetName: The name of asset as string, for example "ten", "btc", "eth".
decimalString: A decimal number formatted as string, for example "0.001".
epoch: Number that represents Unix timestamp in seconds, for example 1638853254 is equal to UTC time "2021-12-07 05:00:54".

HTTP API private

Authentication

HTTP API private requires authentication using API and Secret keys. Both of those keys can be obtained through Trade API. The API key must be sent along with the request inside the custom HTTP header Key value. The Secret key is used to compute HMAC-SHA512 of the request’s query (when using the HTTP GET or DELETE method) or request’s body (when using the POST or PUT method), which then encoded using hexadecimal. The result then sent inside the custom HTTP header Sign value.

For request using HTTP POST and parameters in the body, the request header must set the Content-Type value to application/x-www-form-urlencoded.

All requests must include a timestamp field that contains the value of the current Unix timestamp in seconds. Make sure the client operating system sync their time with the nearest time server, otherwise the request will be rejected if the timestamp value has 8 seconds differences with the server time.

For example, given an API key XYZ and Secret key secr3t, if we want to get trade history for pair ten_btc the query string would be,

timestamp=1574423788&pair=ten_btc

Note: 1574423788 is the example of epoch time that represent UTC time "2021-12-07 05:56:28".

First, compute the HMAC-SHA512 of query string using the Secret key,

hash := HMAC_SHA512("timestamp=1574423788&pair=ten_btc", "secr3t")

Then encode the resulting hash into hexadecimal,

sign := HEX(hash)

Withdraw asset

Transfer the asset from Tokenomy to an external account or other exchange.

This method requires "withdraw" permission to be enabled and a non-empty Callback URL when generating the API key.

The callback URL is an endpoint that will be called by our system to verify the withdrawal request. The withdraw parameters in the request will be forwarded to the Callback URL for confirmation. If all the request parameters are valid, the Callback URL should respond with HTTP status code 200 and print out a string “ok” (without quotes). We will continue the withdraw process only if we receive an HTTP status code 200 response, otherwise, the withdrawal request will be canceled.

Request

POST /v2/user/withdraw
Key: <API key>
Sign: <Signature of body using HMAC-SHA512>

timestamp=&request_id=&asset=&address=&amount=&memo=

Parameters in the body,

timestamp: Required, epoch. Unix timestamp when requests being made.
request_id: Required, string. Custom string to identify each withdrawal request. The request_id will be passed to the Callback URL to allow the receiver to identify the withdrawal request. The request_id must be less than 255 characters and only contains alphanumeric characters.
asset: Required, string. The name of the asset to be withdrawn.
address: Required, string. Receiver address.
amount: Required, float. Amount to be withdrawn.
memo: Optional (depends on the receiver), string. Memo to be sent to the receiver address. Some exchanges use a memo to accept deposits for certain assets. For example, on Ripple the memo value is custom Destination Tag, on NXT the memo value is custom Message, in BitShares the memo value is custom Memo.

WebSocket

Tokenomy API v2 provides two WebSocket endpoints, one is for public consumption and another one is for private, registered account only.

Message Format

All messages between client and server must be sent using WebSocket TEXT operation code (0x02) and encoded using JSON.

Request schema

The WebSocket request mimic the HTTP request as JSON object,

{
    "id": <number>,
    "method": <string>,
    "target": <string>,
    "body": <JSON encoded with base64>
}

The id field must be unique between requests. The recommended value is using Unix timestamp in milliseconds. If a client sent two requests with the same ID, the server will still process it but the client may receive an unexpected response.

The method field is equal to one of the HTTP methods: GET, POST, PUT, or DELETE.

The target field contains the API to be called on the server, its equal to the path in HTTP API.

The body field may contain JSON encoded with base64 that as an argument to "target".

Response schema

The WebSocket response message is represented by the following JSON object,

{
    "id": <number>,
    "code": <number>,
    "message": <string>,
    "body": <base64 JSON encoded string>
}

There are two modes of response that the client will receive: normal mode and broadcast mode. In the normal mode, the response is a reply from the request. In broadcast mode, the response is a message from the server after the client successfully connected to the server.

In normal mode, the id field will be set to the id in the client request. In broadcast mode, the id is zero.

In normal mode, the code field is equal to the HTTP response, 200 for successful request, 4xx client error, or 5xx for server error. In broadcast mode, its value is zero.

In normal mode, the message field will be set to success or error message in a single line. In broadcast mode, its value is equal to the topic that sends the message.

In normal mode, the body field will contain any data requested by the client. In broadcast mode, its value is equal to data sent by the topic’s publisher.

WebSocket public

This WebSocket API does not require authentication.

The client can open a new public WebSocket connection through /v2/ws endpoint.

Market depths

Get the market depths for single pair.

Method: GET
Target: /v2/market/depths
Parameters:
- pair: Required, string; the name of pair

Example,

{
    "id": 1,
    "method": "GET",
    "target": "/v2/market/depths",
    "body": "eyJwYWlyIjoidGVuX2J0YyJ9" // Equal to {"pair":"ten_btc"}"
}

Market prices

Get the latest market price for all pairs.

Method: GET
Target: /v2/market/prices

Example,

{
    "id": 1,
    "method": "GET",
    "target": "/v2/market/prices",
}

Market summaries

Get the market summaries for all pairs.

Method: GET
Target: /v2/market/summaries

Example,

{
    "id": 1,
    "method": "GET",
    "target": "/v2/market/summaries"
}

Market trades

List all completed trades in the market by specific pair.

Method: GET
Target: /v2/market/trades
Parameters:
- pair: Required, string. The name of the pair using "<coin>_<base>" format.
- offset: Optional, number. The number of records to be skipped, default to 0.
- limit: Optional, number. The number of records to be fetched, default to 100.

Example

{
    "id": 1,
    "method": "GET",
    "target": "/v2/market/trades",
    "body": "eyJwYWlyIjoidGVuX2J0YyJ9" // Equal to {"pair":"ten_btc"}"
}

Market ticker

Fetch the pair information related to prices including sell, buy, highest, lowest, and the last price, also and volume of base and coin.

Method: GET
Target: /v2/market/ticker
Parameters:
- pair: Required, string. The name of the pair in the format "<coin>_<base>".

Example,

{
    "id": 1,
    "method": "GET",
    "target": "/v2/market/ticker",
    "body": "eyJwYWlyIjoidGVuX2J0YyJ9" // Equal to {"pair":"ten_btc"}"
}

Subscription

Subscription is an API that allows clients to be notified when servers have new data on a specific topic. For example, instead of calling "/v2/market/depths" with parameter pair "ten_btc" every 10 seconds, clients can subscribe to the topic "depths" and when servers have a new depths data for pair "ten_btc" they will send it to the client connection immediately.

Available topics and its value for subscription APIs,

depths: The subscription value is list of pair, for example ["ten_btc", "eth_btc"]. This topic will broadcast latest volume of open orders (asks and bids) based on pair.
trades: The subscription value is list of pair, for example ["ten_btc", "eth_btc"]. This topic will broadcast latest open order and closed orders for the subscribed pairs.
summaries: The subscription value is boolean true or false. This topic will broadcast the market information on all active pairs, including latest prices, price past 24 hours ago, and tickers.

List subscription

An API to get a list of client subscriptions on the server.

Request

{
    "id": <timestamp>,
    "method": "GET",
    "target": "/v2/ws/subscription"
}

Response

On success, it will return a list of key-value of the topic and its pair.

{
    "<topic>": [ *<pairName> ]
}

Example

Assume that client has subscribe to topic "depth" and "trades" on pair "ten_btc"; given the following request,

{
    "id": 1,
    "method": "GET",
    "target": "/v2/ws/subscription"
}

It will return the following response,

{
    "id": 1,
    "code": 200,
    "body": "ewogICAgICAgICJkZXB0aCI6IFsidGVuX2J0YyIsICJldGhfYnRjIl0sCiAgICAgICAgInRyYWRlcyI6IFsidGVuX2J0YyJdLAogICAgICAgICJ0aWNrZXIiOiBbXQp9"
}

The body when decoded using base64 will result in

{
    "trades": ["ten_btc"],
}

Subscribe to a specific topic by pair names.

Multiple calls on this endpoint will not clear previously subscribed pairs. For example, if the first call subscribed to the topic "trades" with pair "X" and the second call subscribed to the topic "trades" but different pair "Y", the client has two subscriptions: "X" and "Y", NOT "Y".

Request

The subscribe parameter is a JSON object with key as topic and list of pairs in values.

{
    "id": <epoch>,
    "method": "POST",
    "target": "/v2/ws/subscription",
    "body": <base64>{
        "<topic>": [ <boolean> | *<pairName> ]
    }

For example, if we want to be notified when there is a new open order on pair TEN_BTC,

{
    "id": 1639973898,
    "method": "POST",
    "target": "/v2/ws/subscription",
    "body": "eyJ0cmFkZXMiOlsidGVuX2J0YyJdfQ=="
}

The body field is base64 of the following JSON string,

{"trades":["ten_btc"]}

Response

On success it will return list of subscription.

Unsubscribe

The API to unsubscribe from specific topics by pair name or boolean value.

Request

The unsubscribe parameters is JSON object with key as topic and list of pairs in values.

{
    "id": <timestamp>,
    "method": "DELETE",
    "target": "/v2/ws/subscription",
    "body": base64{
        "<topic>": [ <boolean> | *<pairName> ]
    }
}

Response

On success, it will return a list of subscriptions.

Broadcast notifications

Once the client has subscribed to specific topics and pairs, they will receive a broadcast message related to those topics.

For the topic "trades" client will receive two message types

open order with message field value "/v2/market/trades/open", and

{
    "id": 0,
    "message": "/v2/market/trades/open",
    "body": base64<Trade>
}

closed or canceled order with message field value "/v2/market/trades"

{
    "id": 0,
    "message": "/v2/market/trades",
    "body": base64<Trade>
}

WebSocket private

This WebSocket API requires authentication.

Authentication

The client opens a new private WebSocket connection on /v2/user/ws bypassing the API key and signature of the timestamp.
