OWLRACLE The multichain Gas tracker API

Owlracle provides statistical information about gas prices for multiple chains. We can help you save time and money by suggesting the optimal gas-related values before sending your transactions.

Owlracle says you should pay no more than this for Gas on network:

If you are a software developer, and want to integrate your application with our gas oracle, you can use our endpoints.

Gas fee estimation

Retrieve gas for network. If you prefer another network, replace for the corresponding network symbol. Check our header for the supported network list.

Owlracle scans recent past blocks (blocks param) to build an estimative of required gas fee to be paid. It looks for the minimum gas accepted on a transaction for every scanned block (based on the chosen percentile). Then it shows you the minimum gas you should pay to be accepted on a percentage of your choice (accept param) of those blocks.

Gas history

Retrieve the price history for gas, token price and fee for network. If you prefer another network, replace for the corresponding network symbol. Check our header for the supported network list.

The API will return an array of candlesticks built from aggregate data of the requested timeframe. The array is ordered from decreasing timestamps.

API keys

When you access our endpoints, it is reccomended that you use an API key. You can request our data up to times per hour for free. After reaching that limit, you can continue to make requests either waiting a few minutes or using your api credit. You can also make requests without an api key for testing purposes, up to times per hour.

Profile window

You can use the button below or the header section of this page to create new API keys, get information, logs, update, or even recharge your key should you need to use more than the free limit per hour.

Please keep in mind that you should use your API key in your server's code, never in the front-end code, mainly because of these two reasons:

You can make your calls to our endpoints in your server code, save the result in a file or database, then every time your users request the information you can send the cached result. Remember to schedule calls to our endpoints at regular intervals to make sure your cached data is always up-to-date.

API Credit

After reaching the free request limit ( requests in the last hour), each new request will subtract $ USD from your API account.

Any time you want to recharge your API credit, you can use the same Manage API keys button above or the header to open the Recharge key tab. You will be asked to connect your wallet using Metamask extension. This window will let you transfer to Owlracle's wallet any amount of while using the network. The amount transferred will be converted to USD and credited in your account. After the transfer confirmation, our server will update your API credit automatically. Keep in mind that the amount credited may vary depending of the token exchange rate.
