# Nicrron > One OpenAI-compatible API for chat, embedding, audio, image and video models from many providers, with routing slugs, fallback models and caching. Base URL: https://api.nicrron.ai/v1. Keys look like sk-af-…; send them as `Authorization: Bearer`. Prices are each provider's list price. Requests paid from credits add a 5% platform fee; with your own provider key, the provider bills you and Nicrron charges 5% of the list price. We never store chat prompts. Completions are cached for up to 24 hours, only for your account, when temperature is 0 or you opt in. ## Get started - [Overview](https://nicrron.ai/docs): What Nicrron is, a first request, and where everything is. - [Quickstart](https://nicrron.ai/docs/quickstart): Point the OpenAI SDK at Nicrron and send a first request. - [Authentication](https://nicrron.ai/docs/authentication): API keys, your own provider keys, and keeping them safe. - [SDKs](https://nicrron.ai/docs/sdks): OpenAI SDKs for Python and TypeScript, and LangChain. ## API - [API reference](https://nicrron.ai/docs/api): Every endpoint, parameter, header and error code. - [Models and routing](https://nicrron.ai/docs/models): The live catalog with prices, the routing slugs, and provider data terms. ## Capabilities - [Embeddings](https://nicrron.ai/docs/embeddings): OpenAI, Mistral and Voyage behind /v1/embeddings. - [Video and images](https://nicrron.ai/docs/media): Async generation jobs, charged upfront, refunded on failure. - [Audio](https://nicrron.ai/docs/audio): Text to speech and Whisper transcription. - [Model Arena](https://nicrron.ai/docs/arena): Compare models on one prompt for speed and cost. ## Operate - [Teams and alerts](https://nicrron.ai/docs/teams-alerts): Shared wallets, roles, and email and signed webhook alerts. - [Observability](https://nicrron.ai/docs/observability): Logs, latency, provider health and export. - [Data privacy](https://nicrron.ai/docs/privacy): What is kept, what never is, and each provider's terms. ## Machine-readable - [OpenAPI 3.1 spec](https://nicrron.ai/openapi.json): every public endpoint, request and response - [Model list](https://api.nicrron.ai/v1/models): every model with context length and per-token prices, as JSON; no key needed
