Hey there! Great question—you absolutely can pull Ethereum (ETH) price data using the Coinbase API, even if the initial examples you found focused on Bitcoin. The core endpoints work the same way; you just need to adjust the currency pair parameter.

Using the Spot Price Endpoint #

The simplest way to get the current ETH spot price is with the public /v2/prices/{currency_pair}/spot endpoint. No API keys are required for this public data.

Example with curl:

curl https://api.coinbase.com/v2/prices/ETH-USD/spot

Example with Python (using requests):

import requests

response = requests.get("https://api.coinbase.com/v2/prices/ETH-USD/spot")
if response.status_code == 200:
    eth_price = response.json()["data"]["amount"]
    print(f"Current ETH-USD price: ${eth_price}")
else:
    print(f"Error fetching data: {response.status_code}")

You can swap out USD for other fiat currencies too (like EUR, GBP, etc.) by changing the currency pair to ETH-EUR, ETH-GBP, etc.

Fetching Historical Price Data #

If you need historical ETH prices, use the /v2/prices/{currency_pair}/historic endpoint. You can add query parameters to specify a date range:

Example curl for a 7-day date range:

curl "https://api.coinbase.com/v2/prices/ETH-USD/historic?start=2024-05-01T00:00:00Z&end=2024-05-07T23:59:59Z"

The response will include a list of timestamped price points you can parse for trends or analysis.

Quick Note #

The Coinbase API docs do cover this, but sometimes examples are Bitcoin-focused. Just remember that any endpoint using a currency_pair parameter works with Ethereum (and most other supported assets) by replacing BTC with ETH in the pair string.
