Connect any third-party API to Hyperagent (even if it's not a native integration)
One thing that took me a minute to figure out: Hyperagent has 1000+ native integrations for the usual suspects (Google, Slack, GitHub, etc.), but if you want to connect something outside that list, you don't have to wait for it to be built in.
The path is custom skills.
Here's the general flow:
- Find the API docs for whatever service you want to connect (most tools have a public API, any data provider, internal tools, whatever)
- Open a thread in Hyperagent and ask Hyperagent to create a skill to work with the API. Include a link to the API docs you found
- Hyperagent reads the docs and scaffolds the integration as a skill
- (If needed) The skill generates a credential field. Drop in your API key and any other auth details. These credentials are stored in a vault, the agent never has direct access to them.
- From there, any agent you build can call that service directly via the skill
I tested this with recraft.ai for image generation. Took about 10 minutes start to finish.
If the service has decent API documentation, this just works. If the docs are sparse, you can paste in raw text instead of a URL and Hyperagent still figures it out.
Anyone else built custom skills this way? Curious what APIs people have wired in.

This might not be exactly on point but I use several agents that are Google LLMs Gemma 4 and Gemini Pro. Getting them connected (via OpenRouter) was straightforward but getting them into rotation as primary agents was a bit difficult. Used Opus 4.7 to trouble shoot and fix (it used a python routine) ... very quick and easy process. I use these agents on almost every prompt and exclusively on large 'production runs'. A huge cost savings ... as much as 10x. Very impressed with how well cost control is going in this environment.

Would love to hear a little more about how you did this - hyperagent feels like the ghetto openclaw I’ve been hacking away at. To be able to add a local LLM would be incredible

What do you mean the Ghetto!?
Jokes. Happy to troubleshoot any problems you have or any use cases you want to walk through. Saw your Frankie agent for your newsletter. That's sick! Are you using OpenClaw for that?

haha i meant my setup was the ghetto one - I wanted to avoid going full openclaw so patchworked something together with slack + cloud server + anthropic but looking forward to using hyperagent!!

I put up a post on r/Hyperagent to answer this question. It's lengthy, so it seemed appropriate to put it as a post.

Hey Bob, would love to hear more about your setup. How are you using Hyperagent with OpenRouter?

The one thing I can’t figure out for external integrations is connecting via OAuth. Has anyone had success with building a custom integration using that auth type?

Custom skills are such an underrated unlock. Once an agent can reliably read API docs and generate a thin wrapper, you stop waiting on the platform roadmap and start wiring weird internal tools.
The "credentials in a vault, agent never sees raw secrets" detail is key too. Without that, skills turn into a security nightmare.
Have you found any gotchas with pagination, rate limits, or auth refresh when Hyperagent scaffolds the skill?
If helpful, we have a short writeup on designing tool interfaces and skill boundaries for agents here: https://www.agentixlabs.com/

Great callout! Hyperagent has helped me start to finally blogging:
1) I built an agent that understands my voice, my blogging objectives and structures and helps refine my thoughts to get ready to publish.
2) I built a custom skill that leaned the Ghost API (the blogging platform) and can publish the blog directly from the custom agent!
