All of OpenAI, plus 600+ models
One API key for GPT-5.6, Claude, Gemini, Mistral, Llama, and every major model. Automatic failover when providers go down. Cost optimization that saves 30-60%.
client = OpenAI(
api_key="sk-...",
)
// Only OpenAI models
// No failover when OpenAI is down
// No cost optimization
// No EU data residency
// No cross-provider routing
client = OpenAI(
base_url="https://router.requesty.ai/v1",
api_key="rq-...",
)
// 600+ models from all providers
// Auto-failover across providers
// 40-60% cost savings with caching
// EU hosting available (Frankfurt)
// Latency-based routing
Why teams add a gateway in front of OpenAI
Keep using GPT-5.6. Add failover, cost savings, and access to every other model through the same API.
Automatic failover
When OpenAI rate-limits or goes down, requests automatically route to Claude, Gemini, or other providers. Zero downtime for your users.
Cost optimization
Route each request to the cheapest model that meets your quality bar. Prompt caching saves 40-60% on repeated patterns. One invoice for all providers.
Multi-provider access
GPT-5.6, Claude, Gemini, Mistral, Llama, DeepSeek, and 600+ models through one API key. No separate accounts or billing.
Enterprise governance
RBAC, budget controls per team, audit logs, content guardrails, and compliance certifications. Everything OpenAI lacks for teams.
Latency-based routing
Automatically routes to the fastest available provider. When one provider is slow, your requests go elsewhere in real time.
EU data residency
Route through Frankfurt for GDPR compliance. OpenAI processes everything in the US with no EU hosting option.
OpenAI direct vs. Requesty gateway
Same models, same API format. Requesty adds multi-provider access, reliability, and governance.
Frequently asked questions
Common questions about switching from OpenAI direct to Requesty
Requesty is a drop-in replacement that uses the same OpenAI-compatible API format. You change the base URL and API key, then your existing code works with 600+ models from OpenAI, Anthropic, Google, Mistral, and more. You keep full access to GPT-5.6 and all OpenAI models while gaining failover, cost optimization, and multi-provider flexibility.
Requesty automatically detects failures and routes requests to equivalent models from other providers (like Claude or Gemini). Your application stays online with zero code changes. The failover happens in milliseconds at the gateway level.
Teams typically save 30-60% through three mechanisms: automatic prompt caching (reuses responses for repeated patterns), cost-optimized routing (picks the cheapest model meeting your quality threshold), and competitive provider pricing (some providers offer the same models cheaper than OpenAI direct).
No. Requesty uses the OpenAI SDK format. You change two lines: the base_url and the api_key. All your existing chat completions, embeddings, and function calling code works unchanged.
LiteLLM is a self-hosted proxy you need to deploy, scale, and maintain yourself. OpenRouter is a US-only aggregator with no governance or analytics. Requesty is a fully managed AI gateway with enterprise features: 99.99% uptime SLA, latency-based routing, EU hosting, RBAC policies, and real-time cost analytics. No infrastructure to manage.
Yes. Requesty offers an EU gateway endpoint (router.eu.requesty.ai) hosted in Frankfurt, Germany. All requests stay within the EU. A GDPR Article 28 DPA is available. With zero data retention enabled, request and response bodies are never stored.
