Latitude/Longitude Parsing & Coordinate Conversion API Overview

The Latitude/Longitude Parsing & Coordinate Conversion API helps developers quickly process coordinate parsing and transformation within their systems. It returns structured results and is ideal for business integration, automated API calls, and system connectivity.

Use Cases

Integrate latitude/longitude parsing and coordinate conversion capabilities into internal systems, SaaS platforms, automated workflows, or admin dashboards.
Ideal for business scenarios requiring stable API calls, standardized responses, and orchestratable interfaces.
We recommend implementing rate limiting, retry mechanisms, and result caching to improve overall integration stability.

Integration Guidelines

Verify request parameter formats, authentication methods, and error code handling logic before integration.
For high-frequency parsing scenarios, ensure proper log tracking, timeout control, and idempotency handling.
If the results are used for risk control or automated decision-making, we recommend applying secondary validation based on your business rules rather than relying solely on the API response.

Integration Examples

Includes ready-to-use Shell, Python, Go, Java, and PHP examples for direct integration.

Request Example

{
  "lng": 116.397428,
  "lat": 39.90923,
  "from": "wgs84",
  "to": "gcj02"
}

Response Example

{
  "code": "SUCCESS",
  "message": "success",
  "data": {
    "lng": 116.403694,
    "lat": 39.91487
  }
}
