A metered AI usage billing infrastructure for indie SaaS builders that handles token counting, user-level quota enforcement, subscription tier gating, and overage alerts as a single embeddable middlew
Every developer shipping an AI product right now has to reinvent token metering and quota logic and there is no Stripe equivalent for AI usage billing yet
Built for SaaS founders monetizing AI features via token-based subscription tiers on customer-facing chat products..
Target solo founders and small teams building on OpenAI who need Stripe-grade billing logic for tokens but cannot afford to build it in-house
“Im creating a website that uses API but I want to monitor the number of tokens users use on the chats so that they have to purchase different subscription tiers…”
💰 Willingness to pay, in their words
“Im creating a website that uses API but I want to monitor the number of tokens users use on the chats so that they have to purchase different subscription tiers in order to get more usage.”

Why this is a gap
Surfaced from a high-intensity complaint with clear willingness to pay and a specific, reachable audience.
The market
SaaS founders offering AI-powered chat features who need token-level billing granularity for subscription tiers. No search volume data; competition is high (8/10) because OpenAI usage monitoring is a known, solved problem in the ecosystem.
Competition & the opening
OpenAI's native dashboard, third-party monitoring dashboards (Helicone, Humanloop, custom solutions), and billing APIs already exist. The gap is a lightweight, embeddable widget or SDK that lets founders surface real-time token usage to end-users inside their product.
real pricing Metronome (acquired by Stripe) from 0.8% of billing volume; $0.04 per 1k events after 10M included; Stripe Billing approximately $72/month
What's hard to build
Ingesting, aggregating, and displaying token counts in real-time requires close coupling with OpenAI's API and careful handling of async requests to avoid billing delays. Keeping the service low-latency and reliable across thousands of concurrent users is operationally hard.
Why now
Token-based pricing models are fragmented across OpenAI and competitors, forcing builders to reinvent metering for each tier.
