See it in action
The AI App Template is built on Cloudflare's Agents framework with At Your Service integrated: sign-in, capped promo credits, real-time billing and top-ups, all wired up.
AI App Template
Clone it, deploy it, and your first integrated app is free. It is the same template the demos on this site are built from.
Two ways to integrate
Depending on how your app handles sign-in today.
Users sign in through At Your Service
A complete sign-in flow, branded for the platform. For MVPs, demos, or apps without their own auth. The user sees: "Sign in to use [your app]".
Add a "Link your AI wallet" button
The lighter integration, for apps that already handle their own auth. The user sees: "Link your At Your Service wallet".
Both modes route every LLM call through the wallet gateway for metering, billing and cost optimisation. A custom domain such as ai.yourapp.com is optional.
Integration made simple
How your users pay
What is included
Peace of mind, instant validation, and zero complexity.
AI wallet integration
Users link their AI wallet and use your app with promo credits straight away. The gateway handles usage billing and tracking transparently.
Capped promo trials
Set promo credit limits per user, say $0.50. Users try freely until the credits run out, then top up or use their own keys. No surprise bills: the cost is capped up front.
Usage-based billing
One credit equals one dollar, charged at LLM cost plus a minimal markup. Users know exactly what they are paying for, and you set the promotional amount that sponsors a risk-free trial.
Full visibility
Track every token and see which users convert to paid usage. LLM usage and costs in real time, with full transparency and zero liability.
Built by an engineer who saw viral success turn devastating
Fred, the founder, was lead AI engineer at an AI platform that went viral and then almost went bankrupt: over a hundred thousand people tried it, thousands used it regularly, the LLM bills piled up, and only a handful ever paid. Free AI usage without limits is a liability, and this is the tool he wishes had existed then.
Questions
Does OAuth add friction?
Only slightly. Most users already log in with Google or GitHub anyway, so it is one OAuth popup instead of pasting API keys, at the same trust level as the sign-ins they already use.
What if users run out of credits?
They can top up with a card, switch to their own API keys, or use promotional credits you provide. Your application is never interrupted and there is no billing to reconcile on your side.
What if I want to charge a monthly fee?
At Your Service strictly covers LLM usage costs. You can charge for access to your app independently of the LLM usage costs.
Does the gateway store all my LLM traffic?
You control retention. Choose no logging at all for maximum privacy, or a retention period for troubleshooting and quality evaluation.
Ship the feature. Let the user pay the tokens.
Swap your OpenAI or Anthropic base URL for ours, add the sign-in, and your users pay their own AI usage from the first request.
