What the data for this category looks like
Data sources include the industry monitoring database of the China Chemical Fiber Industry Association and financing filing data from domestic commodity spot trading platforms. The update cadence is full data update for the previous trading day completed by 8:30 AM daily. The document structure is a structured table with five core fields: product name, total daily financing credit line, average single financing interest rate, inventory turnover days, and spot transaction average price. The units are ten thousand yuan, %, days, and yuan/ton respectively.
Constraints for tool calling and plugins
To support multiple data sources, the tool must connect to both the industry association and spot platform APIs. Two independent sets of authentication parameters and request headers must be configured. The fixed daily update schedule requires the tool trigger to be bound to a daily scheduled task. This avoids pulling outdated data that has not completed updating. The fixed field structure of the structured table requires the tool call to explicitly specify extracted fields. The structure of returned content cannot be adjusted arbitrarily. Unit differences across fields require configuring field format validation rules during tool calling. This prevents calculation errors caused by mismatched units. The chemical fiber category has many sub-varieties. The tool must support filtering by product name as a parameter to accurately pull financing data for the target category.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
request_timeout | 600 seconds | Adapts to the average latency of pulling industry data across multiple platforms, avoids timeout errors caused by overly slow data retrieval |
cron_schedule | 0 30 8 * | Matches the daily data update cadence of completing updates by 8:30 AM, ensures the latest previous day’s data is pulled |
field_whitelist | ["品种名称","当日融资授信总额","单笔融资平均利率","库存周转天数","现货成交均价"] | Only extracts preset core fields to avoid redundant data interfering with tool call results |
auth_config | Configure API_KEY and request headers separately for each data source | Adapts to the authentication requirements of multi-source data integration, distinguishes authentication rules for the industry association and spot platform |
data_unit_convert | Match corresponding units by field | Ensures credit line values are output in ten thousand yuan and transaction average prices in yuan/ton for consistent formatting, avoids unit confusion |
filter_params | Support passing "品种名称" as a filter condition | Adapts to the large number of sub-varieties in the chemical fiber category, accurately pulls financing data for specified products |
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 Configuration Mistakes
- Phenomenon: The tool call returns a
400 Bad Requesterror, prompting that the request path was not found. Cause: The data source API request address was not configured correctly, and the test environment address was directly reused in the production environment. - Phenomenon: No data is returned after the tool is triggered on a schedule, and the workflow log shows authentication failure. Cause: Independent authentication parameters were not configured separately for the industry association and spot platform, causing one of the data sources to fail verification.
- Phenomenon: The units of financing data fields returned by the tool are inconsistent. Some credit line data is displayed only as a plain number without attached unit values. Cause: The
data_unit_convertrule was not configured, and no standardized processing was applied to the units of different fields.
How to Verify Successful Configuration
- Manually trigger the tool call, check if the returned fields exactly match the preset
field_whitelist. - View the workflow log, confirm that the request headers and authentication parameters of the tool call match the configured
auth_config. - Verify the scheduled task trigger time, confirm it matches the
cron_scheduleexpression. - Enter the specified chemical fiber product name as a filter parameter, check if the tool only returns data for the corresponding category.
