AI Gateway for B2B SaaS Platforms

Adding Generative AI features to a multi-tenant B2B SaaS product fundamentally breaks traditional software pricing models. You are no longer paying for relatively fixed, static compute hours; you are carrying the highly variable, unpredictable cost of third-party API tokens generated directly by your users' behavior.

Without an AI gateway managing this traffic, you have fundamentally lost control of your Profit margins.

The Multi-Tenant Threat Vector

Consider an enterprise customer running an automated CI/CD script against your new AI document extraction tool. They could unintentionally generate millions of output tokens over a weekend. Because your backend blindly passes those requests to OpenAI using your root API key, you could easily land a $15,000 API bill by Monday morning.

01. Dynamic Virtual Keys

Never expose your root API credentials. Hyperion generates scoped Virtual Keys for your backend per-tenant, mapping all downstream requests to specific organizational budgets and rulesets.

02. Anomaly Auto-Pause

Detect abuse immediately. If Customer B's request volume spikes 500% above their standard 30-day baseline within a single hour, Hyperion's anomaly detector instantly blocks the tenant's virtual key and triggers a PagerDuty alert to your team.

03. Tiered Rate Limiting

Enforce fair usage policies dynamically. Assign Free tier users an IP-based limit of 10 requests per minute, while passing Enterprise tier requests through completely unthrottled.

04. Tenant-Level Caching

Ensure complete data isolation. Hyperion's semantic cache strictly partitions vector namespaces by tenant ID. A cached query generated by Company A can never accidentally be retrieved by a prompt from Company B.

"Hyperion provided the missing billing layer for our Generative AI infrastructure. We simply set a webhook from Hyperion to Stripe, and suddenly we were effortlessly billing all 4,000 organizations for their exact fractional token usage every month."— VP of Engineering, Data Integration SaaS

Usage-Based Billing Integration

To charge your customers accurately for their AI usage, you need exact token counts across massive scale and concurrency. Hyperion attaches a highly-accurate, normalized cost footprint to every single request passing through the gateway. It perfectly blends costs across raw input tokens, semantic cache hits (free), and expensive generation tokens.

You can query this aggregated data directly from our metrics API via GraphQL, or configure continuous automated webhooks to sync usage events straight into standard billing engines like Stripe Meters, Metronome, or Lago.

SaaS Infrastructure FAQs

Common questions about multi-tenant configuration, rate limits, and billing.

Hyperion provides Virtual Keys tied to specific Tenant IDs. You can assign a hard $100/mo limit to Customer A. Once they hit it, Hyperion intercepts further requests with a 429 error, protecting your underlying provider account.
