Authentication - CryptoQuant API

Each API request requires authentication to identify the member. Authentication is provided through an access token. The token is unique, issued for each client. You can authenticate in one of two ways.

Access token (recommended)

Include the Authorization HTTP header with Bearer <YOUR_API_KEY> in every request.

GET /v1/{PATH} HTTP/1.1
Host: api.cryptoquant.com
Authorization: Bearer <YOUR_API_KEY>

import requests

headers = {"Authorization": "Bearer " + API_KEY}
response = requests.get(URL, headers=headers)

const response = await fetch(URL, {
  headers: { Authorization: `Bearer ${API_KEY}` },
});

Query parameter

Alternatively, pass your key as the api_key query parameter.

GET /v1/{PATH}?api_key={API_KEY} HTTP/1.1
Host: api.cryptoquant.com

import requests

response = requests.get(URL, params={"api_key": API_KEY})

const response = await fetch(`${URL}?api_key=${API_KEY}`);

Prefer the Authorization header over the query parameter — URLs are often logged by proxies and analytics, which can leak keys passed as query parameters.
