Important Update: WebSocket Endpoint Migration
We are excited to announce an upgrade to our WebSocket service! To ensure that our users enjoy enhanced reliability and performance, we have migrated our WebSocket endpoint. Please update your applications to connect to the new endpoint as described here:

❌ Old Endpoint: wss://ws.web3api.io/

✅ New Endpoint: wss://ws.amberdata.com/spot

Action Required
Users are required to update the endpoint URL in their applications. The good news is that the response JSON schemas remain unchanged, so you can expect a seamless transition with minimal adjustments needed on your end.
Support
We understand that changes like these can raise questions. Our support team is here to assist with any issues or concerns you may have during this migration process. Please don’t hesitate to contact us for support at: [email protected].
We appreciate your prompt action to migrate to the new WebSocket endpoint.

Once you're connected to this subscription: wss://ws.amberdata.com/spot, you must provide either the instrument or exchange - one needs to be specified, both cannot be empty.
