Tool Calling and Plugins for Coke Financing Daily Reports

Coke financing daily report data mainly comes from Dalian Commodity Exchange public delivery data, spot financing ledgers from multiple domestic coal

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 ItemRecommended ValueRationale
tool_call_cron0 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_templatecarbon_coke_finance_daily_standardBinds the pre-configured standard field mapping for coke financing daily reports to ensure accurate field extraction
unit_validation_switchtrueVerifies unit consistency for pledged tons and financing amounts to prevent unit deviations across data sources
api_request_timeout600 secondsAdapts to the processing duration of multi-source data merging to avoid request interruption from early timeout
tool_call_rate_limit1 time per 24 hoursAligns 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 Requests error code. Cause: The tool_call_rate_limit parameter 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_switch is 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_cron is 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_timeout parameter 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.
