Turn OpenAPI and Swagger specs into AI-ready function calls
Ingest standard OpenAPI or Swagger specifications and export function-call parameters ready for AI model tool use.
Generates compact parameter definitions that reduce the context cost of exposing large API surfaces to language models.
Designed to work with popular model endpoints including ChatGPT/OpenAI, Claude, Gemini and Llama family models.
A hosted web service, so teams can convert specs through the browser without maintaining parsing infrastructure.
One OpenAI-compatible gateway for adaptive LLM routing, guardrails, and spend control
Each prompt is graded and routed to the model that clears your quality bar, with configurable fallback chains that retry before a response starts.
Pay provider prices with $0 per-token added on pay-as-you-go and subscriptions, or bring your own provider keys and credits.
PII shielding, jailbreak and injection blocking, and per-call approval for tool and MCP actions run before you are billed.
Request logs, per-prompt receipts, routing and spend dashboards, and copy-as-cURL make every call auditable and attributable.

#1Provides access to a massive catalog of frontier models with flexible routing, but lacks OrcaRouter's dedicated enterprise governance.

The environments frontier AI trains on, and the agents that do the recurring work

One OpenAI-compatible API key for 500+ AI models

Free / Open-sourceOffers an open-source proxy and SDK for unifying 100+ LLMs with failover, requiring self-hosting rather than a managed service.


Routes requests across frontier models with automatic failover and analytics, serving as a straightforward alternative API proxy.
Free / Open-sourceReactive TypeScript backend with database, functions and AI gateway
Gives developers a single OpenAI-compatible endpoint for multiple LLMs with failover, but offers fewer advanced routing rules.
Delivers enterprise-grade LLM gateway features with advanced caching and observability, though at a higher operational complexity.

Unifies multi-provider model access with built-in governance and cost tracking, but functions more as a broad AI marketplace.
Free / Open-sourceProvides an open-source gateway for unifying model access and failover, but demands self-management and infrastructure setup.
