Introduction

CMC_API is a Python-client for the Coin Market Cap API.

This client provides support for the basic or free tier at the moment. However, it is open for extension to anyone who has access to paid packages.

It provides access to all the available endpoint on the API and produce a result similar to the original API with some minor difference. The most relevant difference is the addition of a list of keys available in each answer, as shown in the bellow example.

{
      "metadata": {
            "timestamp": "2022-06-04T04:26:55.117Z",
            "credit_count": 0,
            "error_message": null,
            "list_keys": [
                  "plan",
                  "usage"
            ]
      },
...

About

The CoinMarketCap API is an API provided by the company with the same name. This API provides cryptocurrency data such as price, volume, market cap, and exchange data.

This project is a wrapper around this API that facilitates its usage for python projects.

Why use the Client:

1. It will reduce the coding time since the code for request and parsing of the data is already done, and the user only needs to call a function.
2. It provides the option to save the response data to save in credit calls for data that is not updated constantly.
3. It provides metadata information in the response. This metadata contains the "cost" per request in credits and a list of the keys in the data part of the response so users can retrieve information with ease.

Usage

1. Decided with URL you will use:
   1. BASE:base is the real API and provide the real data. cmc_helper.Urls.BASE.value
   2. SANDBOX: sandbox is for testing, and returns dummy data. cmc_helper.Urls.SANDBOX.value
2. Create an Object of class Cmc(), passing the URL to be use cmc = Cmc(url=cmc_helper.Urls.BASE.value)
3. use the object of type Cmc() to call a function. cmc.get_cmc_id_map()

from cmc_api import cmc, cmc_helper

base_url = cmc_helper.Urls.BASE.value
cmc = cmc.Cmc(url=base_url, api_key="YOU_LICENSE_KEY", save_to_json=True)
cmc.get_cmc_id_map(listing_status="active", start=1, limit=1000)

The response will be similar to:

{
  "metadata": {
    "timestamp": "2022-06-04T13:14:05.108Z",
    "credit_count": 1,
    "error_message": null,
    "list_keys": [
      "id",
      "name",
      "symbol",
      "slug",
      "rank",
      "is_active",
      "first_historical_data",
      "last_historical_data",
      "platform"
    ]
  },
  "data": [
    {
      "id": 1,
      "name": "Bitcoin",
      "symbol": "BTC",
      "slug": "bitcoin",
      "rank": 1,
      "is_active": 1,
      "first_historical_data": "2013-04-28T18:47:21.000Z",
      "last_historical_data": "2022-06-04T13:09:00.000Z",
      "platform": null
    },
    ...
  ]
}
