What the data for this category looks like
Data for chemical fiber financing daily reports is sourced from publicly disclosed information from domestic bulk commodity spot trading markets and daily monitoring reports from chemical fiber industry self-regulatory organizations. Full data updates are completed within 1 hour after the close of each trading day. Individual data records are stored in structured format, with core fields including trading variety, daily financing purchase amount, financing balance, securities lending sale volume, and daily settlement price. Amount fields use the unit RMB ten thousand yuan. Volume fields use trading lots. Settlement price uses the unit RMB yuan per ton.
Constraints imposed by these characteristics on HTTP interfaces and external systems
The data sources for chemical fiber financing daily reports are scattered, with a concentrated update window. This requires HTTP interfaces to support aggregation and pulling of multi-source data, to prevent overall data lag caused by delays in single-source interfaces. The 1-hour post-close update schedule for each trading day requires setting the interface request timeout threshold to no less than 45 minutes, to accommodate full data pull times. Structured data with multiple varieties and fields requires interfaces to support filtering results by trading variety and date parameters. It also requires built-in field unit conversion logic to unify units of amounts and trading volumes from different sources into standard formats, reducing adaptation costs for external systems.
How to Set Configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
apiTimeout | 45 minutes | Accommodates the time required to pull full data for chemical fiber financing daily reports, avoids triggering timeout errors |
fieldMapping | Map source fields to standard names, unify units to ten thousand yuan / trading lots / yuan per ton | Resolves inconsistencies in field names and units across multi-source data, simplifies parsing for external systems |
maxBatchSize | Customized based on business scenarios | Controls the number of data entries returned in a single interface request, optimizes loading performance for external systems |
sourceAuthType | API_KEY authentication | Adapts to authentication requirements for most public industry data sources, standardizes docking processes |
updateSchedule | Trigger within 1 hour after the close of each trading day | Matches the update rhythm of industry data, ensures access to the latest financing daily report data |
responseFormat | JSON structured format | Standardizes return format, facilitates direct parsing and processing by external systems |
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. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Symptom: Calling a connected large model interface returns
500 Internal Server Error, and no corresponding request logs can be found in the platform backend. Cause: TheapiLogEnableconfiguration is not enabled, and storage of interface request logs is not activated, making it impossible to troubleshoot the cause of the call failure. - Symptom: The chemical fiber variety fields received by the external system do not match the locally maintained category list. Cause: The
fieldMappingrule is not configured, and non-standard variety fields from source data are not mapped to unified names for the target system. - Symptom: Interface requests triggered outside the update window on a trading day return empty data. Cause: Pulling is not triggered according to the
updateScheduleconfiguration. At this time, the industry data source has not completed the day's data update, so no valid content is returned.
How to Verify Configurations Are Correct
- Initiate an interface request filtered by specified trading day and variety, check that returned field names and units match the configured standard format.
- View interface logs in the platform backend, confirm that the request trigger time matches the configured
updateSchedule. - Upload test chemical fiber industry documents, confirm that the interface can receive and complete parsing normally.
- Call the batch data interface, check that the number of returned entries matches the configured
maxBatchSizesetting.
