What Data for This Category Looks Like
Data for the chemical fiber category comes from public market data on domestic bulk commodity spot trading platforms, listed contract data from futures exchanges, and supply and demand briefings released by industry associations. Update frequencies vary across data sources:
- Spot market data updates daily on trading days
- Futures market data is pushed in real time during trading hours
- Industry supply and demand data updates weekly
The structure of individual data documents includes product identifier, daily benchmark price, daily transaction average price, daily trading volume, current total inventory, and data update timestamp. Fields and their units are as follows: product name is text type, benchmark price uses yuan/ton as its unit, transaction average price uses yuan/ton as its unit, trading volume uses tons as its unit, total inventory uses ten thousand tons as its unit, and update time uses ISO format timestamps.
What Constraints These Characteristics Impose on Tool Calling and Plugins
The dispersed multi-data-source nature of chemical fiber category data requires plugins to support parallel multi-source pulling, to avoid retrieving only a single category’s data in a single call. Differences in update frequencies across data sources require tool calling scheduling to distinguish between real-time and scheduled tasks: real-time futures data requires a short polling strategy, while spot and industry data must be triggered on a daily or weekly schedule. The non-uniform field units require plugins to include built-in unit conversion logic, ensuring price data returned by different platforms can be compared consistently. The category covers numerous subdivided products, requiring plugins to support filtering results using the product code parameter to avoid redundant data from unrelated categories. Strict data timeliness requirements mandate verifying the update timestamp during tool calling, only retaining the latest data from the current day.
How to Set Configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
tool_call_timeout | 300 seconds | Chemical fiber data interfaces are mostly public interfaces from bulk commodity platforms, with response delays typically under 120 seconds. Reserving sufficient buffer avoids timeout failures |
plugin_multi_source_concurrency | 2–3 | There are usually no more than 3 types of chemical fiber data sources (spot, futures, industry association). Excessive concurrency will trigger platform rate limits |
stream_response_enabled | false | Chemical fiber market daily report data volume is small, streaming transmission provides no obvious efficiency improvement, and increases the complexity of result stitching |
plugin_data_filter_rule | Only retain data updated on the current day | Market data has strong timeliness, and expired data has no reference value |
plugin_unit_conversion_config | Unify conversion to yuan/ton | The common pricing unit in the chemical fiber industry is yuan/ton, avoiding calculation errors caused by inconsistent units across multi-source data |
plugin_version_match | ≥4.12.0 | The multi-source aggregation function for tool calling becomes stable after this version, avoiding internal errors in lower versions |
The parameter values provided on this page are conventional recommendations used as a starting point 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 settings.
Three Common Mistakes
- Symptom: Frequent tool calling failures occur when calling the chemical fiber market plugin in version V4.12.3. Cause: The tool calling framework in this version does not properly adapt to the parallel pulling logic for multi-source data, leading to interface request conflicts.
- Symptom: When
stream_response_enabledis set totrue, the results returned by tool calling only contain partial fragments, and complete market data cannot be obtained. Cause: The stitching rule for streaming results is not configured, and the response is terminated before waiting for the end marker of the last data packet. - Symptom: When calling an MCP plugin packaged with the SSE protocol in version 4.9.6, the system prompts that this protocol type is not supported. Cause: This version only supports stdio process-based plugins, and does not have a built-in parsing adaptation module for the SSE protocol.
How to Confirm the Configuration Is Complete
- Enter the FastGPT plugin management page, check the status of the configured chemical fiber market plugin, and confirm that the
plugin_version_matchparameter matches the currently deployed version. - Manually trigger a tool call, check if the returned fields include the required preset fields such as
benchmark priceandtransaction average price, and that the units are uniformly set to yuan/ton. - Check the tool calling logs to confirm that all configured data sources have successfully pulled data, with no timeout or permission error prompts.
- Adjust the
tool_call_timeoutparameter, then verify that long-duration multi-source data pulling requests can complete normally without timeout interruptions.
