Human Handoff API

One endpoint. Send a typed question; a person lands the answer with the Ergo Thumb; get a typed answer back with source: "human".

When the machine isn't sure

curl https://ambientprecision.com/v1/handoff \
  -H "Authorization: Bearer $AMBIENT_API_KEY" -H "content-type: application/json" \
  -d '{ "version": "ap-1.0.0",
        "state": { "invoice": { "vendor": "Northwind", "amount": 1240.5 } },
        "questions": { "dup": { "type": "likelihood", "instructions": "Is `invoice` a duplicate?" } } }'

• Versions: ap-latest, ap-preview, pinned ap-1.0.0. The response names the one that answered.
• Limits: 20 requests a second per key; 1,000 human answers a month free during early access.
• Accepts Jev's question format as is (noul, score, choice), and answers in the same shape.
• Machine side, measured live: median - from request to card ready. A person's answer takes seconds to minutes. That is the point.
