Thank you for opening this issue!

🔔 @vinch you might want to have a look.

Under the hood the current API was just making a call to Etherscan's Gas Tracker API endpoint. We can modify the extension to directly call the endpoint at https://docs.etherscan.io/etherscan-v2/api-endpoints/gas-tracker but it will mean a user needs to plug in their own API key. Is probably best for @vinch to weigh in first, though.

I believe it's a good option to consider. The free rate limit is 5 requests per second or 100,000 requests per day (like 1.15 req/s if maxed out and distributed evenly throughout a day). This limit seems sufficient. If there's an option also to choose a frequency, that would be great! Like pulling every 6 seconds or at any other frequency.

We can definitely tweak the interval (see: https://developers.raycast.com/information/lifecycle/background-refresh#manifest).
Let's wait a couple of days until the author can chime in otherwise I'd be happy to modify the extension accordingly.
