What the data for this category looks like
Plastics and rubber market and yield data is primarily sourced from domestic commodity futures exchanges and third-party commodity information platforms. Data update frequency varies by data source. Futures products are updated in real time during trading hours on trading days, while spot products are updated once daily at a fixed time. Each data entry includes standardized fields: product identifier, product name, latest price, settlement price, price change, position volume, trading volume, and statistical timestamp. The units for price and settlement price are yuan/ton, while position volume and trading volume are measured in lots or tons. All fields are structured numerical or text formats with no nested complex hierarchies.
What constraints these characteristics impose on tool calling and plugins
Because the update frequency of data sources differs, futures products require real-time data pulling during trading hours, while spot products require pulling at a fixed daily time. Plugins must support configuring custom trigger timing and update frequencies to adapt to the data acquisition rhythms of both types. Because data fields include clear units and standardized identifiers, parameters for tool calls must specify exact field names to avoid extracting units or non-target category fields alongside results. Because data is in structured format, plugin request and response parsing rules must match the preset field hierarchy, with no need for additional unstructured content cleaning. Because some data sources impose call frequency limits, call rate thresholds must be configured to prevent triggering rate-limiting rules.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
plugin_request_timeout | 30-60 seconds | Response times for plastics and rubber data source interfaces are typically under 10 seconds, with buffer time reserved for network fluctuations |
plugin_trigger_mode | Scheduled trigger + manual trigger | Adapts to differing update rhythms: minute-level scheduling for real-time futures data pulling, daily scheduling for spot data, and supports manual supplementary pulls |
extract_field_list | ["product name", "latest price", "settlement price", "price change", "statistical timestamp"] | Only retains core fields required for yield calculation, avoiding redundant data that consumes computing resources |
request_content_type | application/json or application/x-www-form-urlencoded | Compatible with POST request format requirements of different data sources |
max_retries | 2-3 retries | Addresses temporary network fluctuations or temporary interface rate limits, reducing the probability of single request failure |
plugin_custom_card_enable | Enabled | Supports rendering structured data into custom display cards to meet visualization needs |
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 specific analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Symptom: The plugin returns empty fields or fields with incorrect units. Cause: The exact field names are not specified in
extract_field_list, or the field naming rules of the data source are not matched, resulting in irrelevant content or units being included in extraction results. - Symptom: POST requests return a 415 Unsupported Media Type error. Cause: The
request_content_typeparameter is not configured correctly, and a request format that does not match the data source interface is used. - Symptom: Redundant AI conversation context is included in tool calls, and custom cards fail to display data properly. Cause: Non-essential context association switches are not disabled, or the
plugin_custom_card_enableswitch is not enabled, and a matching card rendering template is not configured.
How to confirm correct configuration
- Initiate a manual plugin call, check whether the returned result fields match those specified in
extract_field_list, and whether the units meet the category requirements. - View plugin call logs to confirm that the request format matches the
request_content_typeparameter configuration, with no 415 Unsupported Media Type errors. - Check the custom card configuration page to confirm that the
plugin_custom_card_enableswitch is enabled, and that template fields match the extracted fields. - View the scheduled task management interface to confirm that the trigger frequency matches the data source's update rhythm, with no duplicate or missing call plans.
