# Monk > Monk is an OpenAI-compatible fusion API for coding agents. Paid keys (`sk-monk-*`) may only call `monk`, `monk-fast`, and `monk-coding`. Base URL: https://monk.party/v1. Protocol: OpenAI Chat Completions, not native Anthropic. Monthly plan: ¥30 for 30 days. Monk fuses Flash-class models behind three combo ids. Configure clients as OpenAI-compatible. Do not use Anthropic / DeepSeek presets, and do not probe `/anthropic/v1/messages` (that path 404s; `both_paths_failed` is a client dual-protocol test, not an outage). ## Docs - [Home](https://monk.party/): purchase, models, curl, WorkBuddy and DSH snippets - [Help Center](https://monk.party/help/): shared parameters and client guides - [Oh My Pi](https://monk.party/help/oh-my-pi.html): `api: openai-completions`, `baseUrl: https://monk.party/v1` - [Open Minis](https://monk.party/help/openminis.html): mobile OpenAI-compatible endpoint - [WorkBuddy](https://monk.party/help/workbuddy.html): Custom provider, URL must be `https://monk.party/v1/chat/completions` - [DeepSeek Harness](https://monk.party/help/dsh.html): custom provider, not the DeepSeek catalog - [Full agent notes](https://monk.party/llms-full.txt): copy-paste configs and failure modes ## Optional - [Sitemap](https://monk.party/sitemap.xml) - [Demo](https://tree.ssgoo.net/): public capability demo (separate host)
