What the data for this category looks like
Minor metal industry data is sourced primarily from public reports released by the National Nonferrous Metals Standardization Technical Committee, industry spot trading platforms, General Administration of Customs import and export data, and monthly disclosure documents from mining enterprises. Spot price data updates daily. Total inventory data updates weekly. Import and export data and industry analysis reports release monthly and quarterly. Most data documents are structured CSV or Excel tables. A small number are PDF industry briefings. Some data is available via standardized API interfaces. Core fields include product name, same-day spot average price (unit: yuan per kilogram or yuan per ton), total inventory (unit: ton), import and export volume (unit: ton). All fields have clear attached units, with no redundant unstructured content.
What Constraints These Characteristics Impose on Tool Calling and Plugins
The multi-frequency update rhythm of minor metal data requires tool calls to match the refresh cycle of the corresponding data source. Spot price tools must be set to call daily or in real time. Inventory and import and export data tools must sync on a weekly or monthly schedule. The characteristic that all fields have clear attached units requires plugins to configure unit verification logic. This prevents numerical deviations caused by cross-unit calls. The need to support multiple product varieties requires plugins to accept batch input of product parameters. Plugins must also be compatible with API authentication rules from different data sources. Some data sources have call frequency limits. Call rate limiting rules must be configured to prevent interface bans. Marketing content must match the latest data. Tool calls must support skipping local cache to pull the latest data source directly. This avoids using expired data and harming content accuracy.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
tool_call_timeout | 300 seconds | Most minor metal spot data interface response times fall between 120-200 seconds. 300 seconds covers most normal response scenarios and avoids timeout interruptions. |
cache_expire_time | 86400 seconds (1 day) | Spot prices update daily. Matching the cache expiration time to the refresh cycle prevents use of expired data. |
max_tool_calls_per_round | 3–5 times | Single-round marketing content generation requires calls to spot, inventory, and import and export data. 3–5 times covers conventional requirements. |
unit_verification_enabled | Enabled | All minor metal data fields have clear attached units. Enabling verification prevents numerical deviations between yuan per kilogram and yuan per ton. |
plugin_api_rate_limit | 100 requests per hour | Free interfaces for most minor metal industry data sources limit calls to 80-120 per hour. 100 requests per hour adapts to most scenarios. |
plugin_schema_import_format | OPENAI V3 schema | FastGPT 4.8.17 supports importing plugins in this format. Standard schema files from industry data interfaces can be reused directly. |
The parameter values provided on this page are common recommendations used as a starting point 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 Misconfigurations
- Issue: In FastGPT 4.8.17, the plugin management page fails to display the import path for custom plugins. A
404 Not Founderror appears on the interface. Cause: Plugins are attempted to be imported in the global settings page instead of the plugin configuration page for the target knowledge base, or plugin development mode is not enabled. - Issue: Tool calls return abnormal minor metal spot price values. For example, a value of 12345 yuan per kilogram appears, while the normal value should be 123.45 yuan per kilogram. Cause: The
unit_verification_enabledconfiguration is not enabled. The plugin does not verify unit fields for input and output, leading to incorrect unit conversion. - Issue: Single-round generated marketing content only includes data for one type of minor metal, and inventory and import and export data are missing. Cause: The
max_tool_calls_per_roundconfiguration is set too low, failing to cover the call requirements for multiple data categories.
How to Verify Proper Configuration
- Navigate to the FastGPT plugin management page, import the OPENAI V3 schema file for the minor metal data interface, and check if the imported interface displays the corresponding fields and units. Confirm the configuration matches the format supported by the current version.
- Submit a tool call request, view the response results in the call logs, and confirm no
429 Too Many Requestserror code is triggered, and the returned data includes the preset core minor metal fields. - Modify the
cache_expire_timeconfiguration, submit two call requests with an interval shorter than this value, and check if the second call directly returns cached data instead of re-pulling the interface. Confirm the cache logic is active. - Set
max_tool_calls_per_roundto 2 times, submit a multi-variety marketing content generation request, and confirm the returned results include fields for two or more types of minor metal data. Verify that batch call functions work correctly.
