Hey there! Great question—let me clear this up for you.

First off, you're totally right about the https://coinbase.com/api/v1/currencies/exchange_rates endpoint: it only updates once per day, so it's not suitable for real-time rate needs.

Luckily, Coinbase provides a v2 API endpoint that delivers real-time (or near-real-time) exchange rates. Here's what you need to know:

• The correct endpoint is GET /v2/exchange-rates
• You can specify a base currency using the currency query parameter (e.g., ?currency=USD to get rates relative to US Dollars)
• This endpoint returns up-to-date rates that reflect current market conditions, unlike the v1 version.

Example Request #

If you send a request like this:

GET https://api.coinbase.com/v2/exchange-rates?currency=USD

You'll get a response containing real-time rates for a wide range of currencies, structured like this (simplified):

{
  "data": {
    "currency": "USD",
    "rates": {
      "BTC": "0.000023",
      "EUR": "0.92",
      "GBP": "0.79",
      // ... many more currencies
    }
  }
}

A quick note: While this endpoint is publicly accessible (no API key required for basic use), if you're integrating it into a production app, make sure to follow Coinbase's API rate limits and guidelines to avoid issues.

So to wrap up: ditch the v1 endpoint and use the v2 /v2/exchange-rates endpoint, and you'll get the real-time exchange rates you need.
