Overview

This node interacts with the CoinGecko API to retrieve a list of supported currencies in a simple format. It is useful for users who want to know which currencies are supported by CoinGecko for price conversions or other cryptocurrency data operations. For example, it can be used to fetch all supported fiat and crypto currencies that can be used as reference currencies in other API calls.

Use Case Examples

1. Fetch the list of all supported currencies to display in a dropdown for user selection in a cryptocurrency dashboard.
2. Retrieve supported currencies to validate user input for currency conversion features.

Output

JSON

• json - The JSON response containing the list of supported currencies

Dependencies

• CoinGecko public API

Troubleshooting

• If the API request fails, check network connectivity and ensure the CoinGecko API endpoint is accessible.
• If the response is empty or unexpected, verify that the operation parameter is correctly set to 'simpleSupportedCurrencies'.
• Handle API rate limits by implementing retry logic or using the 'continue on fail' option in n8n.
