5Swap your current API

If you're currently calling an OpenAI-compatible chat API, the migration is two lines: change the URL and the body shape. Everything else stays the same.

Before — OpenAI-style chat

Typical chat completions call. Returns prose. No provenance.

# OpenAI-compatible / Anthropic / Cohere / etc.
POST https://api.openai.com/v1/chat/completions
Authorization: Bearer sk-...
Content-Type: application/json

{
  "model": "gpt-4o",
  "messages": [
    {"role": "user",
     "content": "What is the MoA of metformin?"}
  ]
}

After — DNAi A2A

Same shape, A2A protocol. Returns Task with response + provenance artifacts.

# DNAi Asha (or any of 11 agents)
POST https://api.askasha.org/a2a/v1/message:send
Authorization: Bearer ak_...
Content-Type: application/json

{
  "message": {
    "role": "user",
    "parts": [{"text": "What is the MoA of metformin?"}]
  },
  "metadata": {"agent_id": "asha"}
}

Want a full A/B harness? examples/evaluation.py calls Asha and your current API on the same questions and writes a side-by-side JSON for review.
