To make it more convenient for developers to locate different API calls, BlockVision supports searching with four filters: App, Method, Code, and Time. The picture below shows the API request record with the filters of “fantom-testnet” as the App, “eth_sendRawTransaction” as the Method, and “-32000” as the Code. On BlockVision’s Dashboard, we can see that the cause of this failed call is “insufficient funds for gas * price + value”.
