Quickstart

Send your first message with a Bearer API key.

curl https://lab.101s.ai/api/v1/chat \
  -H "Authorization: Bearer kst_live_…" \
  -H "Content-Type: application/json" \
  -d '{"message":"What are your support hours?"}'

Drop-in widget

One script tag adds a branded chat widget to any page. No front-end work.

Grounded answers

Answers are grounded in your connected docs, so customers get your voice, not a generic one.

Ships on Friday

Sensible defaults, versioned API, and a status page you can actually trust.
