What data for this category looks like
Financial due diligence data for the chemical fiber industry is sourced primarily from upstream production and downstream trade circulation endpoints of the petrochemical industry chain, as well as public or paid data sources from industry associations and customs. Data update frequencies cover daily (such as spot prices), monthly (such as capacity utilization rates), and quarterly (such as import and export data). Documents are primarily structured CSV/JSON files and industry PDF monthly reports. Fields include aggregated fiber fineness (unit: denier (D)), monofilament breaking strength (unit: centinewton per decitex (cN/dtex)), production capacity, inventory, import and export volume, and more. Some segmented product categories require additional matching of associated raw material PTA data.
Constraints imposed on HTTP interfaces and external systems by these characteristics
The multi-dimensional professional fields and mixed document formats of chemical fiber data impose clear constraints on external interface integration. Structured data must support batch retrieval by field dimensions to avoid overloading single requests with data. Professional terminology and specific units require interface parameters to support unit mapping configuration, preventing errors in field parsing. Long document industry monthly reports require interfaces to support large file uploads and timeout fault tolerance. Scheduled retrieval tasks must align with the daily/monthly update rhythm of data, while also supporting authentication mechanisms for paid data sources.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 2000 MB | Chemical fiber industry monthly reports have large individual file sizes, so upload limits must be relaxed to support complete document import |
PARSE_FILE_TIMEOUT_SECONDS | 900 seconds | Long document parsing consumes significant computing resources, avoiding interruptions to the parsing process due to timeout |
maxContext | 800–1200 characters | Chemical fiber professional terminology is dense, so sufficient context must be retained to improve knowledge base recall accuracy |
Recall Count | Top 8 entries | Chemical fiber industry data has many dimensions, so sufficient entries must be recalled to cover associated information for segmented product categories |
HTTP_REQUEST_TIMEOUT | 60 seconds | Sufficient response time must be reserved when connecting to external industry data source interfaces, adapting to delays in paid APIs |
CERT_MOUNT_PATH | /app/certs | A fixed certificate mount path must be specified during container deployment to ensure normal enabling of HTTPS access |
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 Mistakes
- A POST request to the API returns empty chemical fiber data fields. This occurs because unit mapping rules are not configured in the interface parameters, causing fields with units returned by external systems to fail correct identification.
- Shared API interfaces cannot recall knowledge base content. This occurs because the
maxContextandRecall Countparameter configurations differ between the debugging environment and the online API, causing some professional terminology to fail matching. - Interfaces cannot be accessed normally after mounting HTTPS certificates. This occurs because the certificate mount path is not correctly configured in
docker-compose.yml, causing the container to fail reading certificate files.
How to Verify Proper Configuration
- Send a POST request to the configured interface, check that the returned JSON data includes chemical fiber-specific fields and their corresponding units, with no missing or garbled content.
- Upload a chemical fiber industry PDF monthly report, verify that the parsed knowledge base text includes complete segmented data such as production capacity and prices, with no truncation or loss.
- Test the HTTPS interface using a
curlcommand, confirm that the returned status code is200 OKwith no certificate-related errors. - Call the API to initiate a professional terminology query, check that the recalled knowledge base entries include associated information for chemical fiber segmented product categories, and that the number of entries matches the configured
Recall Countrequirement.
