Legacy endpoint shutdown notice

We will be shutting down our legacy RPC endpoint alchemyapi.io on January 31, 2026. This endpoint was originally deprecated in 2021, and you are likely not impacted by this change. However, if your app is still making RPC requests to this legacy endpoint, please migrate to our current endpoint, g.alchemy.com, which offers significant latency improvements while maintaining the same authentication model and API functionality. No other changes are required beyond updating the endpoint URL in your calls.

If you are using the Ethers.js package, please ensure you are running v6.16.0 or later, which routes requests through the current g.alchemy.com domain.

After the shutdown date, all requests to alchemyapi.io will return HTTP 410 – Gone, and no Compute Units (CUs) will be billed for calls made to the deprecated endpoint.
