Can you provide some more conext? What are you trying to do?

Is there any reason why you're not using slp-sdk? Here is an example of how to send a token using slp-sdk: https://github.com/Bitcoin-com/slp-sdk/blob/master/examples/send-token/send-token.js

Hi Chris, I took the reference of the above code and implemented a rest api for send ingslp tokens. I kind of encounter this error and rest.bitcoin.com/v2/ 502: bad gateway errors occasionally. I just want to cross check if this is usual or is there any better suggestions for the send slp

The current servers are having a hard time with the load, due to popularity of the service. Any code you write that depends on rest.bitcoin.com should be able to auto-retry if it receives a 50X error.

We're in the process of moving the servers to a new data center, which will help us scale with demand.

Thanks a lot for the update Chris..
