What the data for this category looks like
Data sources for this category cover exchange public market APIs, standardized APIs from licensed financial data service providers, and official net value disclosure APIs from product issuers. Full data refresh is completed within 1 to 2 hours after market close on trading days. Only static announcement information is updated on non-trading days. Each data entry includes fields such as 6-digit product code, full product name, daily profit change value, cumulative profit value, net asset value, publish timestamp, and more. Net asset value is expressed in yuan with two decimal places. Daily profit change value is expressed in yuan. Publish timestamps use ISO 8601 format.
What constraints these characteristics impose on tool calling and plugins
An automatic fallback mechanism must be configured for multiple data sources, to switch to standby data sources when the main interface returns an error. Scheduled trigger tasks must be set after the update completes, due to fixed update windows, to avoid fetching unrefreshed old data. Field mapping rules must be configured to convert to a unified format, as fixed field structures have varying field names across different data sources. The product scope for calls must be limited, as each data entry has a fixed number of fields but covers multiple product dimensions, to avoid excessive request data volume causing timeouts. Publish timestamp validation logic must be added, to ensure returned data is the latest valid content updated on the current day.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
plugin_fetch_timeout | 60 seconds | This category’s data updates are concentrated in a narrow window. Single requests must complete within the update completion window. 60 seconds covers response delays for most data sources, preventing call failures due to timeout. |
data_source_fallback | Main interface + standby interface triggered by priority | Multiple data sources require automatic switching logic. The main interface is called first, and the standby interface is automatically triggered when the main interface returns an HTTP 5xx status code or times out, to ensure data availability. |
field_mapping_rules | Map to standard field names: product_code, product_name, daily_profit, net_value, publish_time | Unify field differences across data sources, ensuring downstream processing logic does not need to adapt to multiple field formats. |
trigger_schedule | 16:30 daily on trading days | Aligns with the closing update rhythm of most markets, avoids interface fluctuations during trading hours, and ensures fetching the latest daily data. |
product_filter_list | Whitelist product code list configured per business requirements | Limits the number of products per request, preventing interface rate limiting or timeouts caused by excessive data volume. |
response_validation_schema | Validate that the publish_time field uses the current day’s ISO 8601 format | Filter invalid data not updated on the current day, ensuring returned content meets the timeliness requirements of daily reports. |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- Symptom: Plugin calls return the
required parameter missingerror. Cause: No fallback logic is configured for parameter variables. Default plugin values are not enabled when a specified variable is empty. - Symptom: Scheduled calls return old data, with publish timestamps earlier than the current day. Cause: The trigger task time is set before the market update window, so today’s latest refreshed data is not fetched.
- Symptom: Calls return more data than expected, including unmonitored products. Cause: The
product_filter_listparameter is not configured, so the product scope for calls is not limited, and full market data is pulled.
How to Verify Correct Configuration
- Manually trigger a plugin call, and verify that the returned data fields fully match the preset mapping rules.
- Simulate a timeout or error status returned by the main interface, and confirm that the plugin’s automatic standby data source triggering logic takes effect.
- Call after configuring product filter rules, and verify that returned results only include product information within the specified scope.
- Adjust the trigger task time to a non-update window, and verify that the publish time of the call results meets the update requirements for that window.
