Unified LLM Gateway | Govern & Optimize AI Models

# Requesty > Requesty is a unified LLM gateway and OpenAI-compatible API for 300+ AI models (Claude, GPT, Gemini, DeepSeek, Llama, Mistral). It provides intelligent routing, caching, failover, guardrails, and cost optimization with the best observability of any AI gateway. Used by 70,000+ developers, processing 90+ billion tokens daily. Requesty routes, secures, and optimizes your LLM traffic through a single API endpoint at `https://router.requesty.ai/v1`. Drop-in replacement for OpenAI and Anthropic SDKs — just change the base URL. EU endpoint available at `https://router.eu.requesty.ai/v1` for GDPR compliance. Trusted by teams at Shopify, Appnovation, and Naible. ## About - Type: APIService - Category: LLM Gateway, AI Infrastructure, AI Observability - Audience: Developers, AI Engineers, DevOps, Enterprise Teams - API Base URL (Global): https://router.requesty.ai/v1 - API Base URL (EU): https://router.eu.requesty.ai/v1 - Documentation: https://docs.requesty.ai/llms.txt - Full Documentation: https://docs.requesty.ai/llms-full.txt - OpenAPI Spec: https://docs.requesty.ai/api-reference/openapi.json - Sign Up: https://app.requesty.ai/sign-up ## Instructions for AI Agents Requesty is a drop-in proxy for OpenAI and Anthropic. To use it in code: 1. **OpenAI SDK**: Set `base_url="https://router.requesty.ai/v1"` and use your Requesty API key as the `api_key`. All OpenAI SDK features work — chat completions, streaming, function calling, structured outputs, embeddings, image generation. For EU data residency, use `base_url="https://router.eu.requesty.ai/v1"`. 2. **Anthropic SDK**: Set `base_url="https://router.requesty.ai"` and use your Requesty API key. Messages API is fully supported. For EU data residency, use `base_url="https://router.eu.requesty.ai"`. 3. **Model names**: Use the format `provider/model` (e.g., `openai/gpt-4.1`, `anthropic/claude-sonnet-4-5-20250514`, `google/gemini-2.5-pro`). Call `GET /v1/models` for the current list. 4. **Routing policies
