Let AI agents integrate your product for your customers

Summary

At Lark, we're building a billing platform for modern pricing. Something that truly absorbs all of your billing complexity so that you don’t end up with custom billing logic all over your codebase.

Coding agents have exploded over the last few months and it seems like most code is now being written by agents. For products that require API integrations, if you can make it easier for coding agents to integrate with your product, then you’ll see a spike in successful onboardings. We tried this out at Lark and our customers have loved it!

Here’s a video of Claude code doing the Lark billing integration for dino.uselark.ai. Here’s also the final PR it came up with.

What we did

Billing integrations are complex so a lot of users wanted to delegate the integration work to coding agents. They would explicitly ask for an MCP server, llms.txt, integration prompts for coding agents, etc. 

Recently we updated our quickstart guide to include these things out of the box for our users - 

1. Recommending installing MCP server as the first step: This lets coding agents search our docs and make simple api calls for testing. This makes them a lot more effective at being able to do an integration.

2. Add explicit integration LLM prompts: Each quickstart step now also has an LLM prompt that users can simply paste into Claude code, Cursor, etc, to complete that step. 

3. Make sure your docs site has a good llms.txt (here’s ours). Most documentation platforms should offer this functionality but you might have to enable it. 

Result

Users that have onboarded recently have loved it! We’re also starting to see a decrease in time for account creation to a live integration. 

Other similar examples

I like how the neon python integration guide makes it trivial to set up a simple integration with their database. I tried it out and the agent can one shot it!
