What is Rival
Rival is the platform for AI agents and the tools they call. You can use tools and adopt agents others have published, build your own with an AI assistant, run them from a dashboard or your code, and earn when people use what you publish.
Three surfaces
Everything on Rival happens across three surfaces, all reachable from the left sidebar nav at cortexone.rival.io.
What you can do
- Use a tool or Adopt an agent from the Marketplace and call it via your dashboard or API
- Build a tool in Studio - Function, MCP, or Storm - with RivalBot doing the heavy lifting
- Build an agent in Agent Studio that chats, calls tools, and runs on a schedule via Rituals
- Run from code - every tool has an API endpoint and it can be used with the API keys, which can be created through Settings
- Earn from what you publish - set a price on your tool and you receive 85% of every run
Tool types
A tool is the core unit of work. Rival supports three types:
- Function - a code handler in Python, Python 3.13 — Fast, JavaScript, or Lua. The most flexible type.
- MCP server - a JSON-RPC 2.0 endpoint designed for AI agents to discover and call.
- Storm - a no-code content tagging engine driven by a topic file.
Run Balance and Welcome Credits
Every run debits your Run Balance - your execution quota. Verify your phone after signup and you get the Welcome Credits to spend on running any tool. Plans (Free, Starter, Pro, Team, Enterprise) refill Run Balance on a monthly cycle - see Plans. The Run Balance received with the subscription is expirable and the ones received by the user on top-up or Welcome Credits are non-expirable.
Who Rival is for
