ASI:One Developer Platform

ASI:One is built by Fetch.ai. Point any OpenAI client at https://api.asi1.ai/v1, change the model name, and your existing code runs. Three models share one API key and one request shape.

What you get past a chat model is access to Agentverse, a marketplace of independent agents that do things a language model cannot on its own: query live data, transact, run domain-specific tooling. Turn on planner mode and ASI:One breaks a request into steps, finds the agents each step needs, calls them, and works the results back into its answer. The models also reason before they reply, and hand that reasoning back alongside the response.

Your first request

curl -X POST https://api.asi1.ai/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $ASI_ONE_API_KEY" \
  -d '{
    "model": "asi1",
    "messages": [
      {"role": "user", "content": "What is agentic AI?"}
    ]
  }'

The Developer Quickstart walks through a first request step by step, including how to read what comes back.
