Corrath is a deterministic security gateway that sits between applications and AI providers such as OpenAI, Claude, and Gemini. It neutralizes prompt injection attacks, enforces per-developer spending limits, and reroutes requests during provider outages in under 5ms. The platform includes a semantic firewall, cost forecasting, HMAC-signed webhooks, real-time usage auditing, and multi-provider routing under a single dashboard. Corrath is available on a freemium model with a free tier supporting 500 requests per month and paid plans scaling to enterprise volumes.
