Overview

Welcome to the Coincall API! You can use our API to access Coincall Open API endpoints.

General Information

Some endpoints will require an API Key to access. Please refer to this page to setup API Key.
Base endpoint for REST: https://api.coincall.com
While setting API Key, it is recommended to set IP access whitelist for security.
Never share your API Key/Secret with anyone.
The default permission of newly created API is read-only.
Endpoint returns a JSON object.
All time and timestamp related fields are in milliseconds.

Working with Endpoints

For GETendpoints, parameters must be sent as a query string.
For POSTendpoint, the parameters must be sent in the request body with content type application/json.
Parameters may be sent in any order.
Because the API system is asynchronous, it is normal and expected that there will be a delay in the returned data.

Rate Limits

Endpoint	Rate Limit	Rule
Get Public Configuration	10 / 2s	per IP address and product
Get Funding Rate	10 / 2s	per IP address
Get Position / Open Orders	5 / 1s	per User ID
Get Historical Order / Transactions	4 / 1s	per User ID
Get Account Information	2 / 1s	per User ID
Get Orderbook	30 / 2s	per User ID
Place Order	30 / 2s	per User ID
Cancel Order	30 / 2s	per User ID

Generating API Keys

Create an API Key on the website before signing any requests. After creating an APIKey, keep the following information safe:

APIKey
APISecret

The system returns randomly-generated APIKeys and APISecrets. We cannot recover the APISecrets if you have lost it. You will need to create a new set of APIKey.

ApiKeys and apiSecret are case sensitive.

There are two permissions below that can be associated with an API key. One or more permission can be assigned to any key.

Read-Only - Can request and view public info such as public configurations.

Trade - Can place and cancel orders, and request and view account info such as bills and history.

Endpoint Security Type

Each endpoint has a security type that determines how you will interact with it.
Security type is stated next to the NAME of the endpoint. If no security type is stated, assume the security type is NONE.

Security Type	Description
NONE	Endpoint can be accessed freely.
SIGNED	Requires valid API-Key and Signed.

Making Requests

All private REST requests must contain the following headers:

X-CC-APIKEY The API Key as a String.
sign The Base64-encoded signature (see Signing Messages subsection for details).
ts The timestamp of your request .e.g : 1688436087184
X-REQ-TS-DIFF sent to specify the number of milliseconds after ts the request is valid for. If X-REQ-TS-DIFF is not sent, it defaults to 5000.

Request bodies should have content type application/json and be in valid JSON format.

  if (timestamp < (serverTime + 1000) && (serverTime - timestamp) <= X-REQ-TS-DIFF) {
    // process request
  } else {
    // reject request
  }

Serious trading is about timing.

Networks can be unstable and unreliable, which can lead to requests taking varying amounts of time to reach the servers. With X-REQ-TS-DIFF, you can specify that the request must be processed within a certain number of milliseconds or be rejected by the server.

Signature

Sign Procedures:

Add ? after request uri path, separate each parameter with a & which represents Parameters concatenation, sort them alphabetically. (If no prameter here, can only add ? after request uri path)
Create a prehash string of method + uri + &uuid=your_api_key&ts=your_timestamp&x-req-ts-diff=your_ts_diff (where + represents String concatenation, if no prameter here, please use method + uri + uuid=your_api_key&ts=your_timestamp&x-req-ts-diff=your_ts_diff instead).
Sign the prehash string with the apiSecret using the HMAC SHA256.
Encode the signature in the Base64 format.
The sign should be UPPER.

Example:

your_prehash_string=POST/open/futures/leverage/set/v1?leverage=1&symbol=BTCUSD&uuid=xdtHWn32rsuDQConutzl9JDZB+Y1leitFl356YHrmts=&ts=1688436087184&x-req-ts-diff=3000

sign=hmac.new(your_api_secret.encode('utf-8'), your_prehash_string.encode('utf-8'), hashlib.sha256).hexdigest()

The timestamp value is the same as the ts header with UNIX millisecond timestamp of when the request was created and sent, e.g. 1688436087184

The request method should be in UPPERCASE: e.g. GET and POST.

The uri is the path of requesting an endpoint, separate each parameter with a &, ? represents Parameters concatenation.

Example: /open/futures/leverage/set/v1?leverage=1&symbol=BTCUSD

Your API Secret is generated when you create an APIKey.

code	true	10, build connection
uuid	false	Custom id by user
ts	true	Timestamp, 1687326076897
sign	true	Signature
apiKey	true	your api key

sign: signature string, the signature algorithm is as follows:

First concatenate method + uri + ?uuid=your_api_key&ts=your_timestamp (where + represents String concatenation), then use HMAC SHA256 method to encrypt the concatenated string with apiSecret, and then perform Base64 encoding.

method: always GET.

uri : always /users/self/verify
