API Overview

This API is used to query the historical asset size changes of a specified fund. By passing the fund code, you can obtain the fund's net asset value (in CNY) on different statistical dates and the rate of change compared to the previous statistical period. The data supports paginated returns, making it convenient for developers to integrate into financial terminals or data analysis systems.

Use Cases

Investment Research Data Analysis: Analyze fund size expansion or contraction trends and assess capital flows.
Product Comparison Display: Display historical fund size changes on wealth management platforms to assist user decision-making.
Risk Monitoring: Monitor abnormal fluctuations in fund size and warn of liquidity risks.

Request and Response Details

Request Method: POST
Core Parameters:
fundCode (required): Fund code, e.g., "000001".
pageNo (optional): Page number, defaults to 1.
pageSize (optional): Number of records per page, defaults to 10, maximum 50.
Response Result:
data.list: Contains an array of objects, each including assetDate (statistical date), asset (fund net assets, in CNY), assetRate (rate of change from the previous period).
code: Status code, 200 indicates success.
taskNo: Task number for this request, used for troubleshooting.

Integration Suggestions

Caching Strategy: Fund size data is typically updated quarterly or semi-annually; it is recommended to cache historical data locally to reduce redundant requests.
Error Handling: Please validate the returned code field; if not 200, read msg to get the error message.
Data Interpretation: assetRate is a percentage value; positive numbers indicate growth in size, negative numbers indicate reduction. It needs to be formatted for display in conjunction with specific business logic.

Integration Examples

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