Endpoint reference

Every endpoint lives under the /api/v1 base path, returns JSON and requires an API key

Values in the samples are illustrative placeholders showing the response shape — they are not real output for any parcel.

หมายเหตุ: ฟิลด์วิเคราะห์ (deal_score, deal_class, assessed_price_per_wah) คืนค่า null อยู่ในขณะนี้ทุกแพ็กเกจ — เราจะเปิดใช้งานก็ต่อเมื่อโมเดล ผ่านการทดสอบย้อนหลังกับราคาขายจริงจากกรมบังคับคดีแล้วเท่านั้น ข้อมูลข้อเท็จจริง (ราคา พื้นที่ ทำเล น้ำท่วม ผังเมือง ประวัติการลดราคา) ใช้งานได้ตามปกติ

Authentication

Every request must include an API key via an HTTP header

Send your API key in the X-API-Key header of every request. Keys look like tdiq_live_… — keep them secret and never embed them in web or mobile client code.

X-API-Key: tdiq_live_xxxxxxxx

How to get an API key

Team subscribers can issue a Free Dev (Sandbox) key themselves, instantly, from the dashboard — no waiting on us. The paid data plans (Startup / Business / Enterprise) are still provisioned by our team after we verify your organisation and plan.

cURL

curl -H "X-API-Key: tdiq_live_xxxxxxxx" \
  "https://api.teediniq.com/api/v1/parcels?province=ชลบุรี&deal_class=cheap"

Python (requests)

import requests

resp = requests.get(
    "https://api.teediniq.com/api/v1/parcels",
    headers={"X-API-Key": "tdiq_live_xxxxxxxx"},
    params={"province": "ชลบุรี", "deal_class": "cheap"},
)
data = resp.json()
print(data["total"])

JavaScript (fetch)

const res = await fetch(
  "https://api.teediniq.com/api/v1/parcels?province=ชลบุรี&deal_class=cheap",
  { headers: { "X-API-Key": "tdiq_live_xxxxxxxx" } }
);
const data = await res.json();
console.log(data.total);

Replace tdiq_live_xxxxxxxx with your real key — never commit keys to a repository
