# 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.

## 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**: To add failover, load balancing, or latency-based routing, create a routing policy in the dashboard and use `model="policy/your-policy-name"` in your requests. See the [Fallback Policies docs](https://docs.requesty.ai/features/fallback-policies).

5. **Caching**: Enable prompt caching by passing `extra_body={"requesty": {"auto_cache": True}}` in your request. See [Auto Caching docs](https://docs.requesty.ai/features/auto-caching).

6. **Do not hardcode model versions** — model availability changes. Always call `GET /v1/models` for current availability.
