Setup snapshot

1
Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.
2
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

capsolver-agent

Agent integrations for CapSolver — framework-agnostic tool definitions and LangChain BaseTool implementations.

See the capsolver-ai-hub repo for integration examples and the full documentation.

For framework integration guides (OpenAI, LangChain, LlamaIndex, CrewAI, Google ADK, and more), see docs/agent-integration.md.

Install

pip install capsolver-agent
pip install capsolver-agent[langchain]   # with LangChain support
pip install capsolver-agent[browser]     # with Playwright support (for detect/solve_on_page)

All packages read the API key from the environment:

# bash / zsh
export CAPSOLVER_API_KEY="your-capsolver-api-key"

# PowerShell
$env:CAPSOLVER_API_KEY = "your-capsolver-api-key"

# cmd
set CAPSOLVER_API_KEY=your-capsolver-api-key

Framework-agnostic tools (any LLM / agent framework)

Use schema.py to get tool schemas as JSON and an async executor to run tool calls. Works with OpenAI function calling, OpenAI Agents SDK, Browser Use, or any custom agent loop.

import asyncio
from capsolver_agent.schema import get_all_tools, create_executor

async def main():
    # 1. Get tool schemas — feed to your LLM's function-calling API
    tools = get_all_tools()
    openai_functions = [t.to_openai_function() for t in tools]

    # 2. Execute a tool call returned by the LLM
    executor = create_executor(api_key="YOUR_API_KEY")
    result = await executor.execute("solve_captcha", {
        "captcha_type": "reCaptchaV2",
        "website_url": "https://example.com",
        "website_key": "6Le-wvkSAAAAAPBMRT...",
    })
    print(result)
    # {"success": True, "solution": {"token": "03AF...", ...}}

asyncio.run(main())

Each ToolDef provides two export formats:

tool = get_all_tools()[0]
tool.to_openai_function()  # → OpenAI function-calling schema
tool.to_json_schema()      # → MCP-style tool descriptor (name + inputSchema)

For a quick one-shot call without creating an executor:

from capsolver_agent.schema import execute_tool

result = await execute_tool("solve_captcha", {
    "captcha_type": "reCaptchaV2",
    "website_url": "https://example.com",
    "website_key": "6Le-wvkSAAAAAPBMRT...",
}, api_key="YOUR_API_KEY")

LangChain integration

Pre-built BaseTool subclasses with Pydantic input schemas — plug directly into any LangChain agent.

import asyncio
from capsolver_agent.langchain_tools import get_langchain_tools
from langchain_openai import ChatOpenAI
from langgraph.prebuilt import create_react_agent

tools = get_langchain_tools(api_key="YOUR_API_KEY")

llm = ChatOpenAI(model="gpt-4o")
agent = create_react_agent(llm, tools)

async def main():
    result = await agent.ainvoke({"messages": [...]})

asyncio.run(main())

Or import individual tools:

from capsolver_agent.langchain_tools import SolveCaptchaTool, GetBalanceTool

solver = SolveCaptchaTool(api_key="YOUR_API_KEY")
balance = GetBalanceTool(api_key="YOUR_API_KEY")

CLI

The capsolver-agent command lets you inspect available tools and their schemas from the terminal.

# List all tools with descriptions
capsolver-agent list

# Show JSON Schema for a specific tool
capsolver-agent schema solve_captcha

# Export all tools in OpenAI function-calling format
capsolver-agent schema --format openai

# Export one tool in OpenAI format
capsolver-agent schema --format openai detect_captchas

Also works via python -m capsolver_agent list.

Available tools

| Tool | Browser? | Description | |---|---|---| | solve_captcha | No | Token-mode solving — provide type + URL + site key, get a token back | | detect_captchas | Yes | Scan a page URL and return which captcha types are present | | solve_on_page | Yes | One-shot: detect + solve + autofill all captchas on a page | | get_balance | No | Check account balance and packages | | get_supported_captchas | No | List all supported captcha types and handler names |

Browser-based tools require pip install capsolver-agent[browser] and playwright install chromium.

Integration examples

See the capsolver-ai-hub examples for runnable demos:

openai_function_calling.py — agentic loop with OpenAI function calling
openai_agents.py — OpenAI Agents SDK with @function_tool
langchain_agent.py — LangChain ReAct agent
browser_use_agent.py — Browser Use with @tools.action()
