What the data for this category looks like
Public data for coke comes primarily from Dalian Commodity Exchange, China Coal Industry Association, public ledgers of major domestic coastal ports, and steel mill procurement announcements. Data updates follow three schedules: spot benchmark prices are updated daily after market close, port inventory is updated weekly, and industry supply and demand monthly reports are released monthly. Documents use structured tables as their core, including fields such as spot price, port inventory, steel mill procurement volume, and import and export scale. Price units are yuan per ton, inventory and import/export volume units are ten thousand tons, and procurement volume units are tons per day. No redundant unstructured content is included, and field names are consistent and unambiguous.
What constraints do these characteristics impose on tool calling and plugins
The data characteristics of the coke category create multiple constraints for tool calling and plugin configuration. Data sources are scattered, and update frequencies vary significantly. Set differentiated call frequencies for each data source. For example, call the exchange spot price interface once daily, pull port inventory data once weekly, and trigger industry report parsing processes once monthly. Many structured fields and exclusive units are used. Plugins must include built-in field mapping and unit verification rules to prevent cross-category data mixing. Some data sources require exclusive authorization keys. Plugins must support independent management of multi-data-source keys, and adapt to response delay differences across different interfaces to ensure call stability.
How to set the configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Maximum Retry Count | 2–3 times | Coke data source interfaces have occasional fluctuations; retries can reduce call failure rates |
Call Frequency Configuration | Set by data source category: spot interface 1 time per day, port interface 1 time per week | Match the public update rhythm of different data sources to avoid triggering interface rate limits |
Field Mapping Mode | Strictly match field names | Coke data field names are unified and exclusive; strict matching prevents cross-category data mixing |
Interface Timeout Duration | 600 seconds | Industry monthly reports have large data volumes, requiring longer adaptation for parsing and interface response times |
Multi-Key Authorization | Enable independent key configuration | Different data sources (exchange, port) require independent authorization keys to avoid permission conflicts |
Input Filter Rule | Only pass required business fields | Reduce invalid data transmission and simplify parameter verification logic for tool calls |
The parameter values provided on this page are all conventional recommendations used as a starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis, and it is recommended to test on your own samples before finalizing settings.
Three common errors
- Phenomenon: A
401 Unauthorizederror is returned when calling the coke data tool, or the interface displays the prompt "Invalid API Key". Cause: The global universal API Key and the plugin-specific authorization key are mixed, and the independent key configured for the corresponding data source is not used. - Phenomenon: Tool calls associated with a workflow have no response, or return the prompt "Target resource does not exist". Cause: The call is not initiated using the workflow's unique identifier ID, or the call interface path does not match the workflow deployment configuration.
- Phenomenon: The due diligence report returned by the tool call mixes irrelevant knowledge base retrieval content, or displays duplicate input and output reference fragments. Cause: The global knowledge base recall switch is not turned off in the tool node configuration, and the switch to tool-only call mode is not activated.
How to confirm the configuration is complete
- Initiate a single tool call, check if the fields and units of the returned data match the public data characteristics of the coke category. Adjust the field mapping rules if they do not match.
- View the tool call run logs to confirm that the call frequency matches the categorized settings, with no excess call records.
- Test calls from different data sources to verify that the authorization keys are valid, with no permission error prompts.
- Turn off the global knowledge base recall switch and initiate a call, confirm that the returned result only contains the content from the tool call, with no additional retrieval fragments.
