What the data for this category looks like
Refractory material industry financial report data mainly comes from domestic refractory material industry association quarterly statistical reports, public annual reports of listed refractory material enterprises, and the Ministry of Industry and Information Technology’s building materials industry operation briefings. The update schedule is as follows: industry statistical data is updated quarterly, and corporate financial reports are updated annually and semi-annually.
A single document includes fields such as enterprise name, report period, main business revenue, refractory product output, raw material procurement cost, and kiln lining service cycle. The unit of refractory product output is tons, the unit of main business revenue is RMB yuan, the unit of raw material procurement cost is yuan per ton, and the unit of kiln lining service cycle is months. Most documents are in PDF format or structured Excel spreadsheets.
What constraints do these characteristics impose on HTTP interfaces and external system integration
The data characteristics of refractory material financial reports create three constraints for HTTP interface and external system integration. First, data sources include industry statistical data and corporate financial reports, so the interface must support field mapping configuration for multiple data sources to avoid parsing errors caused by differences in data formats from different sources. Second, the update schedule is quarterly or annual, so the interface does not need frequent pulling, and the polling interval must match the update cycle. Third, core fields are concentrated on output, revenue and consumable parameters related to refractory material business, so the interface must support specified field extraction to reduce invalid data transmission and parsing overhead. Additionally, most documents are in PDF or structured spreadsheet formats, so the interface must support parsing requests for multiple file formats.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 300–600 seconds | Refractory material financial report PDFs usually contain multi-page capacity tables and kiln data, resulting in long parsing times |
UPLOAD_FILE_MAX_SIZE | 500–1000 MB | Single annual financial report PDF of a listed enterprise may contain hundreds of pages of charts and data tables, resulting in large file size |
API_REQUEST_INTERVAL | 86400 seconds | Industry statistical data and corporate financial reports are updated quarterly, so frequent pulling is not required |
FIELD_EXTRACT_FILTER | ["主营业务收入", "耐火材料制品产量", "原材料采购成本", "窑炉内衬使用周期"] | Only extract fields strongly related to refractory material business in financial reports to reduce invalid data |
DATA_SYNC_FREQUENCY | 7776000 seconds (90 days) | Matches the quarterly update schedule of industry statistical data |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require separate analysis, and it is recommended to test on your own samples before finalizing settings.
Three common mistakes
- When calling the API using a custom Python script, a file path error is prompted. The cause is that the mount path of local financial report files and the file storage directory mapping of FastGPT are not correctly configured, and the system-compliant file reading path is not specified in the script.
- A
404 Not Founderror is returned when calling the API. The cause is that the open API interface permission is not enabled in system settings, and the allowed access IP whitelist is not configured. - A model expiration error is returned when calling a localized model. The cause is that the API address and version configuration of the localized model are not updated regularly, and the valid status of the model is not verified.
How to confirm the configuration is complete
- Call the open API task query interface, and check that the returned task status matches the actually submitted refractory material financial report parsing task.
- Upload a single test refractory material financial report file, call the parsing interface, and check that the returned results include the core business fields configured in the preset
FIELD_EXTRACT_FILTER. - View the system operation logs to confirm that the API request interval matches the
API_REQUEST_INTERVALconfiguration, and there are no records of frequent current limiting triggers. - Call the localized model interface, and check that the returned results have no prompts for model status exceptions, and the response format meets preset requirements.
