AI AGENTS API
Build AI agents, one API.
Build autonomous AI agents using function calling and tool use through Runcrate's OpenAI-compatible API. DeepSeek, Llama, Qwen, Claude, and Mistral all support the standard tools format. Define functions, let the model decide when to call them, execute the results, and loop. Build agents that browse the web, query databases, call APIs, and complete multi-step tasks.
QUICK START
Integrate in minutes.
from openai import OpenAI
client = OpenAI(
base_url="https://api.runcrate.ai/v1",
api_key="rc_live_YOUR_API_KEY",
)
tools = [
{
"type": "function",
"function": {
"name": "get_weather",
"description": "Get current weather for a city",
"parameters": {
"type": "object",
"properties": {
"city": {"type": "string", "description": "City name"},
},
"required": ["city"],
},
},
}
]
response = client.chat.completions.create(
model="deepseek-ai/DeepSeek-V3",
messages=[{"role": "user", "content": "What is the weather in Tokyo?"}],
tools=tools,
)
# The model returns a tool_call you can execute
tool_call = response.choices[0].message.tool_calls[0]
print(tool_call.function.name, tool_call.function.arguments)AVAILABLE MODELS

WHY RUNCRATE
Built for production.
OpenAI Tools Format
Standard OpenAI function calling format. Define tools with JSON Schema, the model decides when and how to call them. Works with LangChain, CrewAI, and every OpenAI-compatible agent framework.
Parallel Tool Calls
Models can request multiple tool calls in a single response. Execute them concurrently for faster agent loops and reduced round trips.
Multi-Model Agents
Use different models for different agent tasks. DeepSeek for reasoning, Claude for analysis, Llama for fast tool dispatch. One API key covers all.
MCP Compatible
Build agents that connect to MCP servers for tool discovery and execution. Combine model intelligence with external capabilities.
