Ship production AI features without managing models, context pipelines, or billing infrastructure. One API call — we handle inference, metering, and invoicing.
You focus on your product. We run inference, context injection, tool orchestration, and billing in four steps.
Customer hits your API with their key. We validate and map to Stripe.
System prompt, tools, and RAG context injected automatically.
Request hits Claude. Streams back with full tool execution.
Tokens metered to Stripe in real time. You collect revenue.
We handle the undifferentiated heavy lifting.
Every request runs through your custom system prompt, proprietary tools, and RAG pipeline. Customers get your curated experience — not raw model access.
Stripe-native metering. Every inference fires a meter event. Set your margin, Stripe invoices automatically.
Per-customer keys tied to Stripe subscriptions. Rate-limit by plan, rotate instantly.
SSE-based with chunked token metering. Real-time token arrival.
Customers query their own usage. No bill shock.
HTTPS, CORS, rate limits, idempotent metering, dead-letter retry.
No upfront commitments. Start free, scale to millions.
