Ask HN: Solution for Endless Integration Woes?

I've spent the past year working on AI agents and copilots to help small to medium-sized businesses. In most cases, I've hit roadblocks due to integrating with their booking platforms.

So far, I've just built integrations as they come, but it's definitely hard to scale. Even with AI coding tools, there's a lot to keep track of.

Have any of you found a solution? I'm particularly looking at service booking and appointment scheduling, think hair salons, med spas, and HVAC providers.

I guess I'm looking for something like a Twilio or Plaid that provides a clean API on top of a bunch of messy integrations. Is this out there? Is it worth building if it isn't?
