What the data for this category looks like
Data for paint and ink industry research reports primarily comes from public industry reports released by national coatings industry associations, regular annual reports of listed basic chemical enterprises, brokerage research reports covering the basic chemical sector, and third-party chemical supply chain databases. There are three update schedules: third-party supply chain data is updated daily, industry association quarterly reports are updated each quarter, and brokerage research reports are released irregularly alongside industry developments.
Typical document structures include core supply and demand data, raw material prices, capacity statistics, and policy updates. Some reports break down into specific categories such as water-based coatings and packaging inks. Most fields include clear units; for example, raw material prices are marked in yuan per kilogram or yuan per ton, and capacity is marked in ten thousand tons per year.
What constraints do these characteristics impose on tool calling and plugins
Data sources with different update frequencies require differentiated cache duration configurations for tool calls. Daily updated supply chain data needs a short cache cycle, while quarterly report data can use a longer cache cycle to reduce repeated calls. The presence of unit-attached fields requires plugins to support unit standardization, to avoid confusion between units such as yuan per kilogram and yuan per ton during parsing.
The relatively large number of segmented categories in document structures requires tool call parameters to support filtering conditions for specific segments, to avoid retrieving irrelevant industry data. Multi-source data requires tool calls to limit the range of accessible data sources, to prevent unauthorized calls to interfaces for unrelated chemical categories.
How to set the configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
plugin_request_timeout | 30 seconds | Most external data sources for paint and ink research reports are structured APIs with short response times. Default timeout settings may cause request blocking |
plugin_call_max_tokens | 8000–12000 characters | Core data paragraphs of single research reports are relatively long, requiring sufficient token support for field parsing and content extraction |
recall_top_k | Top 6 entries | The paint and ink segmented market has a narrow audience; excessive recall will introduce irrelevant general chemical data |
plugin_cache_ttl | Set to 86400 seconds for daily data sources, 604800 seconds for quarterly reports | Matches the actual update frequencies of different data sources, balancing data timeliness and call costs |
parse_field_unit_auto | Enabled | Automatically identify units in research report fields, avoiding unit confusion during manual processing |
function_call_allow_list | ["paint_raw_material_price", "ink_capacity_stat"] | Limit calls only to tools related to paint and ink research reports, preventing calls to unrelated interfaces |
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, and it is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Phenomenon: A
504 Gateway Timeouterror is returned when calling a custom external interface. Cause: Theplugin_request_timeoutparameter was not adjusted based on the response time of paint and ink data sources. The default timeout setting is too short, causing the request to be interrupted. - Phenomenon: Fields returned by the tool are empty or have mixed units. Cause: The
parse_field_unit_autoconfiguration was not enabled, and no standardized processing was applied to unit-attached fields in research reports, leading to parsing failures. - Phenomenon: The function call module cannot be found or triggered. Cause: The corresponding tool identifier for paint and ink research report retrieval was not added to
function_call_allow_list, or the platform's overall tool calling switch was not enabled.
How to confirm the configuration is correct
- Initiate a simulated call, check whether the returned research report data includes core fields related to paint and ink, and that units match the preset requirements.
- View the tool call logs, confirm that no timeout errors related to
plugin_request_timeoutare triggered, and that call frequency complies with the configured rate limiting rules. - Check
function_call_allow_list, confirm that the unique identifier of the currently used paint and ink research report retrieval tool has been added. - Test data sources with different update frequencies, confirm that the cache duration matches the actual update rhythm of the data sources.
