How to update API?

[kairoski03]

@AndrewGalak6578 Hello, maybe API providers who implement the API spec will appear and they will maintain and update
following up the changes.
It will be appreciated if you leave questions in below link.

Thank you.

Similar to my notes for SIP-3, while this feature would be very useful to have, it shouldn't be an SIP, as it doesn't involve any changes to core Sui Move codebase or otherwise an ecosystem level change.

This can also just be a PR to the Sui explorer or as a standalone service that can be integrated into wallets and explorers.

Due to the above reasons, I would recommend not moving this proposal to the next stage.

If you have any questions about this, please reach out to me on TG.
