What the data for this category looks like
Financial report data for the chemical fiber industry comes primarily from two sources. These are annual and quarterly reports of listed companies publicly disclosed by domestic and overseas stock exchanges, plus operation reports released by industry associations. Data updates follow two schedules: fixed and event-triggered. Fixed updates include quarterly reports, released every 3 months, and annual reports, released once per year. Event-triggered reports are released when production capacity adjusts or raw material prices fluctuate. The document structure includes core items from consolidated financial statements. It also includes exclusive fields for chemical fiber sub-categories. These fields cover output and production capacity of sub-categories such as polyester and nylon. They also cover raw material (PTA, ethylene glycol) cost ratios. Common units are ten thousand tons for output and capacity, hundred million yuan for revenue, and percentage for cost ratios.
Constraints for HTTP Interfaces and External System Integration
The segmented attributes and fixed update rhythm of chemical fiber financial reports create clear constraints for HTTP interface and external system connections. First, interfaces must support request parameters for filtering by chemical fiber sub-categories. Generic financial report data cannot support segmented business analysis without this functionality. Second, scheduled synchronization tasks must adapt to fixed update cycles. Tasks must trigger updates quarterly and at event-triggered announcement nodes. This avoids unnecessary high-frequency requests. Third, interfaces must return chemical fiber-exclusive fields such as sub-category output and raw material cost ratios. Targeted financial report analysis cannot be completed without these fields. Fourth, the system must support multiple data source formats. Field naming differs between some industry association data and exchange-disclosed data. Interfaces must support lightweight format conversion to accommodate this.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
external_data_source_type | financial_report_api | Standard format for connecting to public financial report data sources, supports filtering for chemical fiber segmented fields |
request_interval | 3600 seconds | Chemical fiber financial reports are updated quarterly or via event announcements. A 1-hour interval aligns with public data update rhythms and avoids triggering data source rate limits |
return_field_list | ["company_name", "report_period", "polyester_output", "pta_cost_ratio", "total_revenue"] | Only returns core fields required for chemical fiber financial report analysis, reducing unnecessary data transmission volume |
timeout_threshold | 120 seconds | External financial report data sources may have delays when loading bulk data. 120 seconds covers most normal request durations |
filter_sub_category | ["polyester_fiber", "polyamide_fiber"] | Only retrieves financial report data for target chemical fiber sub-categories, filtering redundant information from non-target categories |
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
- Calling the
POST /v1/chat/completionsinterface returns400 Bad Requestwith the promptmissing required field 'external_data'. This occurs because the request uses the plain text prompt format of the base model without binding the configured chemical fiber financial report data source parameters. - The financial report data returned by the interface lacks chemical fiber segmented production capacity fields. This happens because the
filter_sub_categoryparameter is not configured. A generic financial report data source is requested without specifying chemical fiber sub-category filtering. The returned data does not include segmented business information. - A scheduled synchronization task returns
429 Too Many Requestsafter triggering. This is caused by an unreasonablerequest_intervalsetting. The request interval is shorter than the external data source's rate limit threshold, triggering access restrictions.
How to Confirm Successful Configuration
- Call the configured HTTP interface. Check if the returned results include preset chemical fiber-exclusive fields such as
polyester_outputandpta_cost_ratio. Confirm that the field matching meets analysis requirements. - Send a test request. Verify that the report period returned by the interface matches the currently disclosed chemical fiber financial report cycle. Confirm that the update rhythm configuration is correct.
- Adjust the
request_intervalparameter. Observe the interface return status codes. Confirm that rate limit errors are not triggered, verifying that the request frequency configuration is reasonable. - Bind the configured external data source to a FastGPT application. Initiate a chemical fiber financial report analysis conversation. Check if the application can complete corresponding analysis based on the returned segmented data. Confirm that the external system connection is active.
