Get a key. Test it. Ship it.

1 · Create your API key

One key per email. Re-registering an email rotates its key and requires the current one.

Create key

Already have a key? Manage it

Paste your current key to see its usage, rotate it, or deactivate it. This works whether you got it here or from an agent that self-onboarded. Lost your key? Get a link by email instead →

2 · Connect an AI agent (Claude Code, etc.)

Your key has to be attached to the connection itself, not typed into a message. Copy the command below (it already has your key in it) and run it in your terminal, once.

That's it: every future render from that agent, in any project on this machine, now works automatically. If an AI agent creates a key for itself mid-conversation, it will show you this same command and ask you to run it, because it can't attach its own key.

3 · Playground (test the REST API directly)

Pick a template, tweak the JSON, render for real. Each render uses one of your 50 monthly credits.
