# API Reference

Blink's integration is designed to be as simple as possible, it only requires switching over to Blink's RPC node endpoint.

This endpoint mirrors the APIs found by other Arbitrum Node providers.

Please reach out via <contact@blinklabs.xyz> to get set up with your own custom endpoint & dashboard.

## Integration Steps

* Acquire custom RPC endpoint via <contact@blinklabs.xyz>
* Switch out existing RPC endpoint for the custom Blink endpoint: `https://arb.blinklabs.xyz/v1/{$API_KEY}`
* Track recoveries via Blink's dashboard
