Connect Claude & ChatGPT to OpenRouter

Ask your AI which OpenRouter models fit a task, what they cost and which providers serve them. It can check your credits, the connected key's limit and your recent activity, and look up the cost of a past generation. It can also send a prompt to another model, create embeddings or generate an image, paid from your OpenRouter credits.

Try asking

“Find a model with a long context window that accepts images.”
The AI searches the model catalog by input modality and sorts the results so you can pick a model ID.
“Which providers serve this model, and at what price?”
It lists the provider endpoints for the model with their prices, context limits and uptime.
“How many credits do I have left?”
It reads your total purchased credits and total usage, so you can see the remaining balance.

What your AI can do

Questions

What can the AI do in OpenRouter?

It can search the model catalog, read model details, list providers and the endpoints that serve a model, list image models, and read your credits, key usage, activity and past generations. It can get chat replies from OpenRouter models, create embeddings and generate images.

Does the AI see my OpenRouter credentials?

No. Your OpenRouter credentials are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start with the catalog and usage tools only. Chat replies, embeddings and images use your OpenRouter credits, and these tools can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT, open Settings › Apps & Connectors › Advanced, turn on Developer mode and add your HeyMyApps link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

HeyMyApps has a free plan with no credit card required. Paid plans bill per completed task. You also need your own OpenRouter account.

Who pays for the models the AI calls?

You do, through your own OpenRouter credits. Chat replies, embeddings and image generation all draw on your balance. The AI can show the connected key's usage and spending limit and your remaining credits, so you can keep an eye on it.
