# AtmoRouter > A usage-based AI inference gateway with OpenAI-compatible Chat Completions and Anthropic-compatible Messages. Human documentation: https://atmorouter.dev/docs/quickstart OpenAI SDK base URL: https://atmorouter.dev/v1. Anthropic SDK base URL: https://atmorouter.dev (without /v1). Use an AtmoRouter API key for inference. Dashboard management APIs use a separate account login session. Never paste real API keys into an external chat. The files below are generated from the same source as the website documentation. Examples are illustrative. Discover current model IDs and prices from GET https://atmorouter.dev/v1/models and the live catalog at https://atmorouter.dev/models. A catalog entry does not guarantee current capacity or compatibility with every feature. Read the compatibility and error guides before integrating. ## Documentation - [Quickstart](https://atmorouter.dev/docs-markdown/quickstart.md): Markdown version of the Quickstart guide. - [Authentication](https://atmorouter.dev/docs-markdown/authentication.md): Markdown version of the Authentication guide. - [API reference](https://atmorouter.dev/docs-markdown/endpoints.md): Markdown version of the API reference guide. - [Compatibility](https://atmorouter.dev/docs-markdown/compatibility.md): Markdown version of the Compatibility guide. - [Models & pricing](https://atmorouter.dev/docs-markdown/models.md): Markdown version of the Models & pricing guide. - [Tool calling & JSON](https://atmorouter.dev/docs-markdown/tool-calling.md): Markdown version of the Tool calling & JSON guide. - [Streaming](https://atmorouter.dev/docs-markdown/streaming.md): Markdown version of the Streaming guide. - [Usage & request timing](https://atmorouter.dev/docs-markdown/observability.md): Markdown version of the Usage & request timing guide. - [Rate limits](https://atmorouter.dev/docs-markdown/rate-limits.md): Markdown version of the Rate limits guide. - [Errors & retries](https://atmorouter.dev/docs-markdown/errors.md): Markdown version of the Errors & retries guide. - [SDKs & agents](https://atmorouter.dev/docs-markdown/sdks.md): Markdown version of the SDKs & agents guide. - [Setup helper](https://atmorouter.dev/docs-markdown/helper.md): Markdown version of the Setup helper guide. - [API keys](https://atmorouter.dev/docs-markdown/api-keys.md): Markdown version of the API keys guide. - [Budgets](https://atmorouter.dev/docs-markdown/budgets.md): Markdown version of the Budgets guide. - [Billing & deposits](https://atmorouter.dev/docs-markdown/billing.md): Markdown version of the Billing & deposits guide. - [Dashboard API](https://atmorouter.dev/docs-markdown/management-api.md): Markdown version of the Dashboard API guide. - [Account & security](https://atmorouter.dev/docs-markdown/account-security.md): Markdown version of the Account & security guide. - [Affiliate](https://atmorouter.dev/docs-markdown/affiliate.md): Markdown version of the Affiliate guide. - [Combos](https://atmorouter.dev/docs-markdown/combos.md): Markdown version of the Combos guide. - [Guides](https://atmorouter.dev/docs-markdown/guides.md): Markdown version of the Guides guide. ## Reference - [Complete documentation](https://atmorouter.dev/llms-full.txt): All documentation sections in one Markdown text file. - [Inference OpenAPI specification](https://atmorouter.dev/openapi.json): Machine-readable implemented inference endpoints and schemas. - [Live models](https://atmorouter.dev/v1/models): Current model IDs and catalog metadata as JSON. - [API status](https://atmorouter.dev/api/public/status): Public availability status as JSON. ## Optional - [FAQ](https://atmorouter.dev/faq): Common account and integration questions. - [Privacy policy](https://atmorouter.dev/privacy): How AtmoRouter handles account and request data. - [Support](mailto:admin@atmorouter.dev): Contact for account and integration help.
