The **Rival Developer Docs** are now live at[docs.cortexone.rival.io](https://docs.cortexone.rival.io). Whether you’re publishing your first tool or integrating the marketplace into an existing workflow, the documentation is structured to get you moving without friction.

Here’s a breakdown of every section and what you’ll find inside.

### **Getting Started**

**[Quickstart](https://docs.cortexone.rival.io/quickstart/)** - A full end-to-end walkthrough: create a tool, write your handler, test it, publish it, generate an API key, and make your first live API call. Designed to be completed in under 5 minutes.

**[Core Concepts](https://docs.cortexone.rival.io/concepts/)** - The foundation. This covers how tools, runtimes, versions, and billing work inside CortexOne before you build anything production-grade.

**[Creating a Tool](https://docs.cortexone.rival.io/creating-tools/)** - A focused guide on the tool creation flow itself, settings, naming conventions, and navigating the build steps inside the platform.

**[Error Reference](https://docs.cortexone.rival.io/errors/)** - A reference index of platform error codes and what each one means, so debugging is a lookup, not a guessing game.

**[Limits](https://docs.cortexone.rival.io/limits/)** - Platform boundaries documented plainly: execution time limits, file size caps, and other constraints to build within from day one.

* * *

### **Writing Code**

Rival supports multiple runtimes, each with its own dedicated guide:

**[Python](https://docs.cortexone.rival.io/writing-code/python/)** - The most library-rich runtime. Built for data processing, ML inference, and anything requiring external dependencies.

**[JavaScript](https://docs.cortexone.rival.io/writing-code/javascript/)** - Lightweight and fast. Optimized for logic-heavy tools, JSON transformations, and cold-start speed.

**[Lua](https://docs.cortexone.rival.io/writing-code/lua/)** - Ultra-fast sandboxed scripting. Minimal overhead, ideal for high-frequency, low-complexity execution.

**[MCP](https://docs.cortexone.rival.io/writing-code/mcp/) (Model Context Protocol)** - Build servers that AI agents can discover and invoke directly. This is the entry point for plugging your tools into agentic workflows.

* * *

### **Managing Tools**

**[Environment Variables](https://docs.cortexone.rival.io/environment-variables/)** - Securely store API keys, tokens, and other sensitive values inside your tool, separate from your code.

**[Testing](https://docs.cortexone.rival.io/testing/)** - Run test events against your code before publishing. Catch issues in a controlled environment before anything reaches production.

**[Versions & Publishing](https://docs.cortexone.rival.io/versions-and-publishing/)** - How versioning works, how to set visibility (private or public), how pricing is applied, and what it means for a version to be locked once published.

**[Digital Assets](https://docs.cortexone.rival.io/digital-assets/)** - How to work with files and external data inside your tools, particularly in the context of Storm-based batch processing.

* * *

### **Marketplace**

**[Browsing & Executing Tools](https://docs.cortexone.rival.io/marketplace/)** - For builders who want to consume tools, not just create them. Covers how to find tools on the marketplace and invoke any of them via a single authenticated API call.

* * *

### **Platform**

**[API Keys](https://docs.cortexone.rival.io/api-keys/)** - Generate and manage the authentication tokens used to invoke tools via the API. Keys are displayed once at creation.

**[Inviting Members](https://docs.cortexone.rival.io/invitations/)** - Add collaborators to your Rival workspace and manage team access.

**[Teams](https://docs.cortexone.rival.io/teams/)** - Organize members, assign roles, and structure your workspace as your team scales.

**[Analytics](https://docs.cortexone.rival.io/analytics/)** - Track tool usage, call volume, and performance data from your dashboard.

**[Payouts](https://docs.cortexone.rival.io/payouts/)** - Everything creators need to know about how and when earnings from marketplace tools are distributed.

**[Refer & Earn](https://docs.cortexone.rival.io/refer-and-earn/)** - Rival’s referral program. Share the platform, earn rewards when your referrals build.

**[Changelog](https://docs.cortexone.rival.io/changelog/)** - A running log of platform updates, new features, and fixes, so you always know what’s changed.
