Predictable backend

Agent loops become less scary when pricing is flat-rate.

Standard API shape

Use chat completions, model listing, and usage metadata.

Privacy defaults

Prompt and response text is not routinely retained as conversation history.

Quick setup

Create an account, copy your yolo_... API key, set your base URL to https://yolo-auto.com/v1, and use a public model from the models page.

For agentic workloads

Yolo-Auto is built for the messy reality of agents: long context, tool calls in surrounding apps, repeated prompts, and unpredictable usage spikes.

Use your own orchestration

Yolo-Auto provides model inference. Your app, framework, or agent controls tools, memory, files, and actions.

Free first request path

Start with a free account, create an API key, and validate your agent against the /v1 endpoint.

Use cases

Who AI Agent API is actually for

AI Agent API is best for developers and power users who want model access inside tools, agents, scripts, and apps, not just a closed consumer chatbot tab.

Positioning

Agents are not normal API consumers

A human chat session is usually linear. An agent session is messy: it inspects files, reasons, retries, summarizes, and may loop while fixing a problem. That usage pattern makes per-token pricing harder to predict.

Yolo-Auto gives agent builders an OpenAI-compatible model backend with no saved prompt history and a flat-rate upgrade path when free testing is not enough.

Implementation

Try AI Agent API with a normal chat completion

The fastest test is a single request against the OpenAI-compatible endpoint. Use your real Yolo-Auto API key, then swap the model ID if the models page shows a newer default.

curl

curl https://yolo-auto.com/v1/chat/completions \
  -H "Authorization: Bearer yolo_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "qwen3.8-27b",
    "messages": [
      { "role": "user", "content": "Plan the next three safe steps for a coding agent working inside a repository." }
    ]
  }'

OpenAI SDK style

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.YOLO_AUTO_API_KEY,
  baseURL: "https://yolo-auto.com/v1"
});

const response = await client.chat.completions.create({
  model: "qwen3.8-27b",
  messages: [{ role: "user", content: "Plan the next three safe steps for a coding agent working inside a repository." }]
});

console.log(response.choices[0]?.message?.content);
