What the data for this category looks like
Coke financing daily report data mainly comes from Dalian Commodity Exchange public delivery data, spot financing ledgers from multiple domestic coal commodity trading platforms, and industry monitoring data from the China Coal Industry Association. The data update schedule completes a full daily update by 3 AM every day. The structure of each daily report is fixed, including fields such as report date, financing entity name, pledged coke tons, financing amount, financing term, and same-day spot benchmark price. The unit of pledged quantity is tons, the unit of financing amount is ten thousand yuan, and the unit of term is calendar days.
What constraints these characteristics impose on tool calling and plugins
The fixed daily update schedule requires tool calling cron triggers to align with the 3 AM daily update node to avoid pulling incomplete, partial data. Multi-source data requires plugins to configure cross-source data merging logic, perform unit alignment checks on fields like pledged tons and financing amounts to prevent calculation deviations from inconsistent units across data sources. The fixed document structure requires tool calling field mapping templates to be pre-bound to the standard fields of coke financing daily reports to avoid subsequent analysis failures from missing or misaligned fields. Some financing data involves industry-sensitive information, so plugins need to configure access whitelist verification rules to restrict unauthorized tool calling requests.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
tool_call_cron | 0 2 3 * * ? | Aligns with the daily 3 AM data source update node to avoid pulling incomplete, partial daily report data |
plugin_api_key_list | ["dce_api_key","coal_trade_api_key","china_coal_assoc_api_key"] | Covers the three core data sources: Dalian Commodity Exchange, multiple domestic coal trading platforms, and industry association |
field_mapping_template | carbon_coke_finance_daily_standard | Binds the pre-configured standard field mapping for coke financing daily reports to ensure accurate field extraction |
unit_validation_switch | true | Verifies unit consistency for pledged tons and financing amounts to prevent unit deviations across data sources |
api_request_timeout | 600 seconds | Adapts to the processing duration of multi-source data merging to avoid request interruption from early timeout |
tool_call_rate_limit | 1 time per 24 hours | Aligns with the daily-only update schedule of the data source to avoid triggering interface rate limiting |
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, and it is recommended to test on your own samples before finalizing.
Three common misconfigurations
- Phenomenon: Tool calling returns the
429 Too Many Requestserror code. Cause: Thetool_call_rate_limitparameter is not configured, and frequent tool calling triggers rate limiting on the data source interface. - Phenomenon: The pledged tons field in the parsed daily report data is empty. Cause: The
unit_validation_switchis not enabled, and the unit formats of different data sources are not aligned, resulting in failed field extraction. - Phenomenon: Tool calling triggered at 2 AM returns empty data. Cause: The configured
tool_call_cronis earlier than the data source update node, pulling incomplete, partially updated data.
How to confirm the configuration is correct
- Manually trigger a tool call, check if the returned data source data includes all pre-configured standard fields, and verify that the field units are consistent.
- View the tool calling logs to confirm there are no timeout interruption log entries, verifying that the
api_request_timeoutparameter takes effect. - Wait until 3 AM the next day, check if the daily coke financing report data is automatically pulled and parsed, verifying the scheduled trigger function.
- Send an unauthorized tool calling request, confirm that the access whitelist verification is triggered, and a permission denied prompt is returned.
