Our API Gateway Access Services

Explore FastRouter capabilities that make free gateway access useful for testing, optimization, and production-ready AI operations.

Gateway Access

Access 100+ AI models through one OpenAI-compatible API with intelligent routing, failover, governance, and unified provider coverage across text, image, video, embeddings, and speech.

Free Platform Trial

Use free credits to build, test, and evaluate FastRouter with no credit card required for initial access, helping teams validate fit before production adoption.

LLM Gateway

Replace provider-specific integrations with a single LLM gateway for OpenAI, Anthropic, Google Gemini, xAI Grok, and more, while keeping applications flexible and easier to maintain.

Model Routing

Automatically route requests based on cost, latency, quality, or throughput, then combine routing with fallback lists for resilient, policy-driven model selection.

Multimodal API

Test image, video, speech, embedding, and text models through the same OpenAI-compatible endpoint, applying consistent governance and observability across every modality.

Governance Controls

Set project limits, API-key spend caps, roles, access controls, logs, and audit trails at the gateway to keep AI usage accountable.

Meet The FastRouter Platform

The platform behind unified production AI access.

FastRouter is built for teams that need more than a simple LLM gateway. Its platform brings model routing, observability, experiment tracking, guardrails, cost governance, evaluations, and consolidated billing into one OpenAI-compatible control plane. The goal is to help developers move faster while giving platform, finance, and security stakeholders the visibility and controls they need for production AI. Instead of maintaining separate provider integrations and dashboards, teams can standardize access through one durable API layer. With free credits and no credit card required for initial access, FastRouter makes it practical to test real workloads, compare providers, and prove the operating model before scaling usage across products and teams.

Frequently Asked Questions

Is FastRouter really OpenAI-compatible?

Yes. FastRouter is designed as an OpenAI-compatible API gateway, so teams can use familiar OpenAI SDK patterns while routing requests through FastRouter’s unified endpoint. Instead of building separate integrations for each provider, you point your application to the FastRouter base URL and access models across OpenAI, Anthropic, Google Gemini, xAI Grok, and others from one control plane.
