Quick start

Every request needs an API key. Use the public sandbox key to try it instantly, then get your own key below.

curl "https://dev.listsiam.com/api/v1/listings?key=ls_demo_publicsandbox®ion=Phuket&limit=5"

Or pass it as a bearer token:

curl -H "Authorization: Bearer ls_demo_publicsandbox" \
  "https://dev.listsiam.com/api/v1/listings?cobroke=1&limit=5"

Authentication

• Pass your key as ?key=YOUR_KEY or header Authorization: Bearer YOUR_KEY.
• Sandbox key (public, rate-limited): ls_demo_publicsandbox
• Missing/invalid keys return 401.
• Base URL: https://dev.listsiam.com/api/v1
