Why Developers Choose a Free Crypto Price API
A Free Crypto Price API allows developers to fetch real-time cryptocurrency metadata, token lists, and individual coin price information without the barrier of subscription fees.

Some of the benefits of using a Free Crypto Price API include:
- No subscription cost or monthly fees.
- Simple endpoint structures.
- Fast response times.
- Good for beginners testing APIs.
- Great for building hobby projects or MVPs.
- Easy integration with tools like Apidog, Postman, and cURL.
In the following sections, we will discuss exactly how to set up and use the Free Crypto Price API in a real development workflow.
Getting Started with the Free Crypto Price API
Step 1: Create an Account
Visit https://freecryptoapi.com and sign up for a free account.
This gives you access to your dashboard, API settings, and documentation.
Step 2: Verify Your Email
After registering, you must verify your account through the confirmation email sent to your inbox.
Without verification, you will not have access to API keys.
Step 3: Get Your API Key
Once verified, open your dashboard.
Here you will find your API Key, which is required for authentication when making API requests.
Always keep this key private.
If it is leaked, regenerate a new one immediately.
Testing the Free Crypto Price API Using Apidog
Apidog is a powerful API testing platform similar to Postman, but often more intuitive for beginners. You can:
- Create API requests.
- Add custom headers.
- Add parameters.
- Save and organize endpoints.
- Inspect real-time responses.
- Track your testing history.
Below is the exact process for testing Free Crypto Price API endpoints in Apidog.
Create a New Project in Apidog
- Open Apidog and click “New Project.”
- Give your project a name like “Crypto Price API Testing.”
- Then click New API Endpoint.
Step1: Testing the "/getCryptoList" Endpoint
What Does This Endpoint Do? /getCryptoList returns a full list of supported cryptocurrency symbols and names.
This is useful when building:
- Search filters
- Token dropdown lists
- Market overview dashboards
- Auto-complete suggestions
1. Setting Up:
- Enter the URL (All queries will be made to this URL):
https://api.freecryptoapi.com/v1/
- To call the endpoint that lists all available cryptocurrencies, add:
getCryptoList
- Your full URL should now be:
https://api.freecryptoapi.com/v1/getCryptoList
2. Add Your Authorization Header:
From the Free Crypto Price API dashboard, copy your API key. Then in Apidog:
- Go to “Headers”
- Add a new header:
| Header Name | Value |
|---|---|
| Authorization | Bearer YOUR_API_KEY |
Replace YOUR_API_KEY with your actual key.
3. Hit SEND:
You should now see a JSON response containing a list of cryptocurrencies the API supports.
Step 2: Testing the /getData Endpoint (Requires Parameters)
Now let’s test an endpoint that accepts custom parameters.
What Does /getData Do? This endpoint returns detailed price data about a specific cryptocurrency, such as:
- Current price
- Market cap
- Percentage changes
- Volume
- High/low values
Perfect for dashboards and trading tools.
1. Enter the URL
https://api.freecryptoapi.com/v1/getData
2. Add the Same Authorization Header
Use the same header from earlier:
Authorization: Bearer YOUR_API_KEY
3. Add Parameters
In the “Params” section of Apidog:
| Name | Value |
|---|---|
| symbol | BTC |
You can replace BTC with: ETH, SOL, DOGE, ADA, or any other supported symbol.
4. Hit SEND
You should receive price and market data for the requested symbol.
Optional: Test Using cURL
If you prefer command-line testing, here is a sample:
curl -X GET "https://api.freecryptoapi.com/v1/getData?symbol=BTC" \
-H "Authorization: Bearer YOUR_API_KEY"
Testing Directly With Swagger UI
The Free Crypto Price API also integrates Swagger UI on its website.
To use it:
- Open the documentation page
- Click Authorize
- Enter your API key
- Select an endpoint (e.g.,
/getData) - Click Execute
Swagger UI is excellent for visual learners, but occasionally the interface may fail to render full responses due to browser caching or internal API delays.
When this happens, testing your endpoints in Apidog provides a more stable experience.
