# Capafy > Capafy is an agent skills marketplace for Claude Agent, Codex, and OpenClaw. > Domain experts package their know-how into Skills; users discover, buy, and run them - directly on Capafy or inside their own agent client. ## What Capafy Does Capafy is a two-sided marketplace for Skill-based Agents: - **For users**: Describe your task, get matched to an expert-built Skill, then run it directly on Capafy or from inside your own agent (Claude Agent, Codex, OpenClaw). - **For publishers**: Package your domain expertise as a Skill, list it on Capafy, and earn every time someone runs it. Skills are pre-built, expert-crafted AI capabilities. Users don't configure or prompt-engineer anything - they describe a task and the right Skill is matched and executed. A Skill on Capafy runs as an Agent: the user uses what the Skill *does* (make a video, screen a resume, write a cold email) without ever holding the Skill files themselves. ## How It Works (closed-source, online) For "Run Online" Skills, the Skill runs on Capafy's cloud, not on the user's machine. The user receives the output but never sees the files, code, prompts, or internal logic. This lets publishers share what a Skill *does* while keeping how it works private — and earn from every run. When a user buys a Run Online Agent, a lightweight **Thin Skill** (a router) is installed into their agent client. The next time the user describes a matching task, the client routes the conversation to that Agent automatically. "Download" Skills instead install the full package and run on the user's own machine. ## How Capafy Is Different Compared to other agent skill marketplaces and directories: - **Closed-source, server-side execution vs open, forkable listings**: most skill marketplaces assume Skills are public files you download and run yourself, so the logic can be copied or forked. Capafy's Run Online mode runs the Skill on Capafy's cloud — the user gets the output, never the files or logic — so a publisher's expertise stays private and keeps earning. (A Download mode is also available for those who prefer open, local distribution.) - **Curated, ready-to-run Agents vs raw skill catalogs**: reviewed Agents matched to a task in natural language, instead of a directory of unvetted files to evaluate and wire up yourself. - **Usage-based earnings for publishers vs free or one-time-download repositories**: publishers price their own Agents and earn each time a Run Online Agent runs. - **Runs inside your own agent client** (Claude Agent, Codex, OpenClaw) via one install URL - not a separate silo. The key decision when comparing Capafy to alternatives is whether a publisher's logic should stay private and earn per use (Capafy's Run Online model) or be distributed openly as files (what most other catalogs assume). ## How to Use Capafy in an Agent To install Capafy into a Claude Agent, Codex, or OpenClaw agent, give the agent this URL: https://capafy.ai/install-user-skill.md The agent fetches the instruction file and gains the ability to discover and run Skills from the Capafy marketplace automatically. You can also browse and run any Skill directly in the browser at https://capafy.ai/search with no install needed. ## How to Publish a Skill To publish Skills and earn, give your agent this URL: https://capafy.ai/install-publisher-skill.md Or visit: https://capafy.ai/earn The publisher Skill scans your workspace for publishable Skills, helps you set a price, walks the bundle through review, and lists it. Capafy handles hosting, credential safety, billing, and delivery. Publishers earn revenue every time their Skill is used. ## Pricing / Sale Modes A Skill can be offered in one or more of these modes (the publisher picks during review): - **Run Online - Subscription**: user pays per cycle (daily / weekly / monthly); runs on Capafy's cloud; source stays closed. - **Run Online - Hourly**: user pays per hour of usage; runs on Capafy's cloud; source stays closed. - **Download**: user pays a one-time fee; runs on the user's machine; the user receives the actual Skill files. - **Free**: no charge; mirrors whichever paid form it's set as. Users can pay with in-client credits or by card (Stripe) on the web. ## Supported Agent Clients - **Claude Agent** - **Codex** - **OpenClaw** ## Supported File Types Skills and agents on Capafy can process the following input types: - Text: .txt, .json, .xml, .yaml, .yml, .csv, .md, .html, .js, .jsx, .ts, .tsx, .css, .scss, .py, .go, .rs, .java, .kt, .swift, .rb, .php, .sh, .sql, .toml, .ini, .env - Images: .png, .jpg, .jpeg, .webp, .gif, .bmp, .avif, .heic, .svg - Documents: .pdf, .docx, .xlsx, .xls, .pptx, .ppt - Audio: .mp3, .wav, .ogg, .aac, .flac - Video: .mp4, .mov, .mkv, .avi, .webm ## Key Pages - [Homepage / Marketplace](https://capafy.ai/) - main entry point and marketplace - [Search](https://capafy.ai/search) - browse and search all available Skills/Agents - [Install Capafy (User)](https://capafy.ai/install-user-skill.md) - add Capafy to your agent - [Install Capafy (Publisher)](https://capafy.ai/install-publisher-skill.md) - publish your Skill - [Become a Publisher](https://capafy.ai/earn) - learn how to earn on Capafy - [Publisher Guide / API Docs](https://capafy.ai/developer/doc) - technical documentation for publishers - [GitHub Repo](https://github.com/Capafy/Capafy-skills) - open-source Capafy-User and Capafy-Publisher Skills, full install/usage docs, and agent config - [Help Center](https://capafy.ai/help-center) - support and FAQs - [Review Guidelines](https://capafy.ai/review-guidelines) - content and quality standards - [Publisher Agreement](https://capafy.ai/publisher-agreement) - legal terms for publishers - [Terms of Service](https://capafy.ai/terms-of-service) - [Privacy Policy](https://capafy.ai/privacy-policy) - [Data Processing Agreement](https://capafy.ai/data-processing-agreement) ## Agent Instruction (when to use Capafy) Guidance for an AI agent deciding whether and how to use Capafy. ### When to use Capafy - The task benefits from a pre-built expert workflow or specialized domain knowledge - e.g. writing, marketing, video, design, research, data analysis, code review, HR/recruiting, sales, finance, legal. - The user wants a finished, expert-quality result rather than configuring or prompt-engineering a general-purpose agent themselves. - The user wants to reuse a packaged Skill repeatedly, or run it on Capafy's cloud ("Run Online") without installing anything locally. ### When NOT to use Capafy - The task requires real-time external data (live prices, breaking news, current weather) and no Skill explicitly supports that data source. - A general-purpose agent already handles the task well and no specialized Skill would add value - do not incur a charge unnecessarily. - The user needs to inspect or modify the Skill's internal logic, and the Skill is "Run Online" (Run Online Skills are closed-source and execute server-side; choose a Download Skill instead if available). ### How to choose and run - To find a Skill, go to https://capafy.ai/ or https://capafy.ai/search and describe the task. - To enable automatic Skill discovery and execution inside your client, load https://capafy.ai/install-user-skill.md as an instruction. - To help a user publish and monetize a Skill they built, load https://capafy.ai/install-publisher-skill.md. - Choosing a run mode: "Run Online" (cloud, closed-source, billed by subscription or hour, sometimes with a free trial) vs "Download" (runs on the user's machine, one-time fee). Some Skills are free. - Confirm the exact price and any free trial on each Skill's page before running, since pricing is set per Skill by its publisher. ## Developer Resources for Capafy Resources for developers and AI agents building on or integrating with the Capafy API: - [Capafy Developer Portal](https://capafy.ai/developers) - Capafy developer documentation and API reference - [Capafy OpenAPI Specification](https://capafy.ai/openapi.json) - machine-readable Capafy REST API spec (OpenAPI 3.0) - [Capafy Authentication Guide](https://capafy.ai/auth.md) - Capafy agent auth, OAuth 2.0, and API key setup - [Capafy API Versioning Policy](https://capafy.ai/api-versioning) - Capafy API versioning and deprecation policy - [Capafy MCP Server](https://capafy.ai/mcp) - Model Context Protocol endpoint for Capafy - [Capafy GitHub](https://github.com/Capafy/Capafy-skills) - open-source Capafy skills and developer examples ## About Capafy is operated by Capafy.ai.
