B2B LLM Usage & Budget Gateway
A middleware API that sits between SaaS applications and LLM providers to enforce hard limits on AI spending per tenant. It prevents infinite prompt loops or heavy users from exhausting the platform's AI budget.
これが重要な理由
As a SaaS founder integrating AI, you face constant anxiety about runaway infrastructure costs. Because standard API providers only offer global budget caps, a single customer caught in an infinite loop or abusing your system can quietly drain your entire monthly budget. You need a way to easily assign and enforce hard financial limits on a per-user basis without writing complex custom token-counting logic into your core application.

Indie hackers and early-stage SaaS founders launching AI-wrapper products.
100,000+
Developer communities and startup launch platforms.
$29/month
10 paying customers routing at least 10,000 API requests per day through the gateway.
MVPの範囲 · 1～2週間
- Set up a fast reverse proxy server in Go or Node.js to intercept API requests.
- Implement a basic authentication system to identify different tenants.
- Integrate directly with the OpenAI API for seamless request passthrough.
- Build an in-memory token counter that tracks usage per individual tenant.
- Write the core logic to reject incoming calls if a tenant exceeds their limit.
- Connect the in-memory token counter to a persistent database like Redis.
- Develop a simple web admin dashboard to adjust budgets per tenant.
- Configure automated email alerts when a tenant reaches 80% of their capacity.
- Create logic to support fallback models when primary budget is exhausted.
- Deploy the proxy to a high-availability cloud provider and publish docs.

失敗する可能性がある理由
自己反論 — 最も重要な信頼のシグナル
- 1Major AI providers might release native per-tenant budgeting features in their own dashboards.
- 2Developers may refuse to route sensitive customer prompts through a third-party startup's proxy.
- 3The added latency from the proxy might degrade the end-user experience unacceptably.
エビデンスの概要
AIがこのインサイトをどのように統合したか — 逐語的な引用はありません
Engineers report significant anxiety regarding unpredictable API bills, specifically citing scenarios where a single bad client loop completely depletes their monthly allowance. Discussions reveal a strong desire for strict monetary caps and routing tools that mitigate unexpected financial drains in multi-tenant environments.
