This endpoint allows you to create tasks that AI agents can execute. You can either:
  • Work on a repository: Provide a repoUrl to have the agent analyze and modify code in a GitHub repository

​
Authentication

To use this API, you need a BLACKBOX API Key. Follow these steps to get your API key:
  1. Click on your Profile Image in the top right corner at cloud.blackbox.ai
  2. Click on “BLACKBOX API Token” from the dropdown menu

Headers

​
Authorization
string
required
API Key of the form Bearer <api_key>.Example: Bearer bb_b41b647ffbfed27f61656049d3eaeef3d903cc503345d9eb80080d98bc0
​
Content-Type

Must be set to application/json.

​
Request

​
prompt
string
required
The task description or instruction for the AI agent to execute. Be specific about what you want the agent to do.Examples:
  • “Create README in French”
  • “Add unit tests for authentication module”
  • “Refactor the database connection logic”
  • “Write a Python script to process CSV files”
​
repoUrl
string
GitHub repository URL to work on. If provided, the agent will clone and work on this repository.Example: https://github.com/<org-name>/<repo-name>.git
​
selectedBranch
string
The branch to work on in the repository. Defaults to main if not specified.Example: main, develop, feature/new-api
​
selectedAgent
string
required
The AI agent to use for executing the task. Each agent has different capabilities and specializations.Available agents:
  • claude - Anthropic’s Claude models (Sonnet 4.5, Sonnet 4, Opus 4)
  • blackbox - BLACKBOX AI models with multiple provider options
  • codex - OpenAI’s GPT models (GPT-5, GPT-4.1)
  • gemini - Google’s Gemini models (2.0 Flash, 2.5 Pro)
Default: blackbox
​
selectedModel
string
required
The specific AI model to use with the selected agent. Each agent supports different models.See the Agent Models section below for available options per agent.Default: blackboxai/blackbox-pro

Usage Modes

​
Repository Mode

When repoUrl is provided, the agent will:
  1. Clone the specified repository
  2. Checkout the selected branch
  3. Analyze the codebase
  4. Execute the task within the repository context
  5. Create commits with the changes
