That’s a really good idea, I love that they even do fake bank cards.
I feel like a self-hosted version would be better though. Having to phone home to their servers could give the game away.

I think this service is already pretty good, but when defending against LLM based attacks, they're a godsend. Current tools don't appear to be too discerning.

Thanks! We also think they’re one of the few things available that work well for agentic threats.
You might find some recent work we did on agent deception interesting as well: https://blog.thinkst.com/2026/09/getting-agents-to-tell-on-t...

Any idea on how to roll-your-own canary token for an unsupported token provider like Cloudflare/Stripe/OpenAI? Do you just make a real Cloudflare/Stripe/OpenAI account, create an API key, and vibecode an alerting system?
I'm kinda surprised that they haven't expanded beyond their existing token providers.

That's the issue. If the first-parties don't provide a means to mint canaries you have to mint your own real keys.

They make credit cards. Obviously they're not real cards but what sort of financial wizardry is required to make that possible? And given it's vibecoded that means Claude knows how to make fake credit cards now?

They’re real virtual cards actually. Source: I added the feature

This feature was removed at some point and I guess added back? What happened there? It's my fav feature :).
Also what service do you use to mint endless virtual cc numbers?

Why is this a given? This service has been around for longer than LLMs have been a thing.

Vibecoding has seriously eroding the trust we have in public software. Hopefully there's some of badge projects can use to clarify how much Ai was in charge of it.
- No LLMs
- LLMs as tools
- LLMs decided some things
- YOLO vibecoded

There are many, many services for programmatically issuing credit cards that you can control from code. For example: https://stripe.com/issuing
