What the data for this category looks like
Paint and ink market yield data is sourced primarily from the publicly monitored database of the China National Coatings Industry Association, and official quotation APIs from national chemical spot trading markets. Data receives a full daily update after 16:00 on working days. No valid updates are provided on non-working days. Each data document groups entries by product grade and production location. Core fields include product code, product name, packaging specification, daily transaction average price, daily trading volume, previous trading day's average price, and associated raw material quotation. Transaction average price is measured in yuan per kilogram. Trading volume is measured in tons. Associated raw material quotation is measured in yuan per ton.
Constraints imposed on tool calling and plugins
Paint and ink category data is only updated on working days. Scheduled tool call configurations must be limited to execution after 17:00 on working days. This avoids pulling incomplete, unupdated data. Data is grouped by product code and location, and includes multi-dimensional associated fields. Tool call parameters must specify precise product code ranges and location filter conditions. Full data pulls will cause the API to return a volume exceeding single-processing limits. Some fields use different units. Configure unified unit conversion logic after tool calls. This ensures downstream modules use standardized data. No valid data is available on non-working days. Add empty data branch handling in plugins. This prevents failed calls from triggering abnormal processes.
How to Set Configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
toolCallTimeout | 600 seconds | The paint and ink data API typically has a response delay of 300-500 seconds. This buffer prevents timeout errors. |
batchProductLimit | First 20 entries | Pulling too many product data entries at once triggers API rate limits. 20 entries aligns with the single-call limits of most trading platforms. |
authApiKeyScope | Bind to the dedicated paint and ink data source | Prevents the {"code":514,"statusText":"unAuthApiKey","message":"common:code_error.e error by limiting authorization scope. |
chatIdTransmitSwitch | Enable and sync transmission | Ensures tool call results can be linked to conversation context and passed to the next AI chat module. |
globalVarUpdatePolicy | Auto-trigger after tool call completes | Syncs newly pulled market data to global variables. This resolves issues with failed global variable updates. |
dataUnitAutoConvert | Enable | Unifies unit standards for transaction average prices and raw material quotations. This adapts to downstream module data usage requirements. |
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 targeted analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Symptom: The market data source API returns the error
{"code":514,"statusText":"unAuthApiKey","message":"common:code_error.e. Cause: The API key is not bound to the dedicated paint and ink data source, exceeding authorized call scope. - Symptom: Tool call return market data does not appear in the next round of AI chat context windows. Cause: The
chatIdTransmitSwitchconfiguration is not enabled, preventing conversation context from linking to tool call results. - Symptom: Paint and ink market data stored in global variables is not updated with tool call results, retaining old data. Cause:
globalVarUpdatePolicyis set to manual trigger, so no automatic trigger occurs after tool calls complete, and the correct update timing is not bound.
How to Confirm Configuration is Correct
- Initiate a manual tool call. Check if returned result fields include preset product codes, transaction average prices, and other content. Verify units match preset standards.
- Review conversation logs. Confirm that the transmitted chatId parameter is synced to the tool call request parameters, with no missing records.
- Trigger a tool call. Check if global variable stored data matches the current call results, confirming updates have taken effect.
- Call the API with a valid API key. Confirm no 514 unauthorized error is returned, verifying authorization configuration is active.
