Network Programming in .NET

Our vehicle API network expands into Taiwan with full motorcycle registration lookups — make, age, engine size, and emissions test history, all in one call.

Taiwan has one of the highest motorcycle densities in the world, with over 14 million registered two-wheelers on its roads. Today, we’re pleased to announce that the /CheckTaiwan endpoint is live — bringing motorcycle registration data from Taiwan’s national vehicle database into our global API network.

What the endpoint returns

A single call to /CheckTaiwan with a Taiwanese plate number returns structured vehicle data covering identity, registration history, and emissions compliance records:

• Make — Manufacturer name (Chinese & romanised)
• Age / Registration year — Year of manufacture and license issue date
• Engine size — Displacement in cc and engine cycle type
• Inspection records — Full emissions test history with HC, CO, and CO₂ readings

Sample lookup: MWN-0076

Here’s what a real response looks like for a 2018 Kymco (光陽) motorcycle:

{
  "Description": "光陽",
  "RegistrationYear": "2018",
  "CarMake": { "CurrentTextValue": "光陽" },
  "EngineSize": "149",
  "ManufactureDate": "01/08/2018",
  "LicenseIssueDate": "05/09/2018",
  "EngineCycle": "四行程",
  "TestRecords": [
    {
      "LicensePlate": "MWN-0076",
      "InspectionType": "定期檢驗",
      "HC_ppm": "102",
      "CO_pct": "0.1",
      "CO2_pct": "14.8",
      "Result": "合格",
      "TestDate": "20240822"
    },
    {
      "LicensePlate": "MWN-0076",
      "InspectionType": "定期檢驗",
      "HC_ppm": "315",
      "CO_pct": "0.1",
      "CO2_pct": "14.9",
      "Result": "合格",
      "TestDate": "20240718"
    }
  ]
}

The TestRecords array is particularly valuable — it provides a full chronological emissions test history, with pass/fail status (合格 = pass), hydrocarbon and carbon monoxide readings, and the serial number of each inspection. This supports fleet compliance monitoring, insurance underwriting, and second-hand vehicle verification use cases.

API endpoint

The endpoint is live now at:

https://www.chepaiapi.tw/api/reg.asmx?op=CheckTaiwan

Full documentation and interactive testing are available at chepaiapi.tw.

Expanding Chinese-language coverage

This launch also deepens our Chinese-language vehicle data coverage. Alongside Taiwan, our mainland China vehicle lookup service at chepaiapi.cn continues to serve customers requiring PRC plate data — together forming a comprehensive Chinese-language API offering across both sides of the strait.

Use cases

The Taiwan endpoint is well-suited to:

• Insurers pricing two-wheeler policies
• Logistics platforms operating scooter fleets
• Used vehicle marketplaces verifying provenance
• KYC and compliance workflows touching Taiwanese vehicle assets

The inclusion of emissions test records is a differentiator that goes beyond simple registration confirmation — providing genuine due diligence depth for any platform that needs it.

Taiwan joins our network of 55+ country vehicle lookup APIs. We’ll continue expanding coverage across Asia Pacific throughout 2026.
