# KeepRouter > KeepRouter is a managed multi-model API gateway with published customer pricing, prepaid pay-as-you-go credit, scoped API keys, compatible OpenAI and Anthropic chat routes, and route-specific endpoints for specialized modalities. Use the live model catalog for current callable model IDs, endpoints, limits, makers, modalities, prices, and trial eligibility. Static pages deliberately do not preserve a model count or price snapshot. ## API entry points - OpenAI-compatible base URL: `https://keeprouter.com/v1` - Anthropic-compatible base URL: `https://keeprouter.com` - Public OpenAPI: https://keeprouter.com/api/openapi.json - Live model JSON: https://keeprouter.com/api/public/models - Exact model JSON: https://keeprouter.com/api/public/model/gpt-6.1-sol (substitute a catalog ID; reviewed models include api_contract endpoint, reasoning and price-policy guidance) - Interactive API reference: https://keeprouter.com/api/docs - Quickstart: https://keeprouter.com/docs/quickstart.md Compatibility is operation- and model-specific. Chat Completions, Responses, Messages, embeddings, images, audio, and other modalities are separate route contracts. Check the model page and test the exact production request instead of assuming universal feature parity. ## Live facts and machine-readable discovery - [Models and current prices](https://keeprouter.com/models.md): live catalog with one Markdown page per canonical model ID. - [Full reference](https://keeprouter.com/llms-full.txt): expanded product facts, live catalog, and the complete public content library. - [AI index](https://keeprouter.com/ai-index.json): compact structured product and discovery manifest. - [KeepRouter Skill](https://keeprouter.com/SKILL.md): agent instructions for authentication, model selection, bounded generation, and errors. Save as `keeprouter/SKILL.md` in your client's skill directory. - [Sitemap](https://keeprouter.com/sitemap.xml): canonical public HTML URLs with freshness dates. - [RSS
