This method is available on Chainstack. Not all Hyperliquid methods are available on Chainstack, as the open-source node implementation does not support them yet — see Hyperliquid methods for the full availability breakdown.
The info endpoint with type: "approvedBuilders" returns the list of builder addresses a user has approved. When a user approves a builder, that builder can attach a builder fee to the user’s orders. Use this method to check which builders a given address has authorized.

Use your own endpoint in your code. The code examples use a placeholder Chainstack endpoint (YOUR_CHAINSTACK_ENDPOINT) — replace it with your own Hyperliquid node endpoint from the Chainstack console. The curl above uses a shared public endpoint for quick checks only; do not use it in production.
