What this category's data looks like
Carbon steel market and yield rate data comes from authoritative domestic steel industry spot quotation platforms and public APIs of futures exchanges. There are two update cycles: spot quotations are updated once daily at fixed times, and futures market data is pushed in real time during trading hours. The document structure uses structured key-value pairs or table formats. Fields include carbon steel category code, origin, specification parameters, spot tax-included unit price, futures main contract settlement price, price change difference, release timestamp. The unit is uniformly yuan/ton, and no proportional percentage data is included.
What constraints do these characteristics impose on tool calling and plugins
The categorized update cycles of carbon steel data require tool calling to distinguish data source trigger timings. Spot calls must be set to trigger at fixed daily times. Futures calls must be bound to scheduled tasks during trading hours. The segmented category and specification fields require that tool calls pass clear filter parameters. Otherwise, the API returns large amounts of redundant or mismatched data. The uniform unit of yuan/ton means plugins do not need additional unit conversion. Plugins must still verify the unit consistency of returned data to avoid subsequent calculation deviations. Some spot platform APIs have call quota limits. Configure current limiting rules to avoid triggering bans.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
tool_call_timeout | 30 seconds | Carbon steel data source APIs typically respond within 10 seconds. 30 seconds covers network fluctuation scenarios and prevents timeout interruptions of calls |
tool_call_rate_limit | 10 requests per minute | Complies with the call quota limits of domestic spot platform public APIs to avoid triggering current limiting bans |
required_tool_params | ["category code", "specification parameters", "data type"] | Carbon steel data requires clear category, specifications, and data type (spot/futures) to return accurate results. Missing parameters will trigger a parameter error |
response_parse_schema | {"fields": ["category code", "spot unit price", "futures settlement price", "price change difference", "release time"]} | Matches the core field requirements of the carbon steel market daily report, filters redundant data to optimize subsequent processing |
plugin_mcp_enabled | Enabled | Standardizes integration with third-party APIs for carbon steel market quotations, and uniformly manages tool calling links and permissions |
The parameter values provided on this page are all conventional recommendations used as starting points for configuration. Actual values are affected by material forms, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing.
Three common mistakes
- Phenomenon: Returns
400 InternalError.Algo.InvalidParametererror. Cause: Failed to pass the carbon steel category code or specification parameters, resulting in missing filter conditions for tool calling, and the API cannot return matching data. - Phenomenon: The number of results returned by tool calling is far higher than expected. Cause: Did not specify the data type in
required_tool_params, the API returns full data mixing spot and futures, resulting in redundant results. - Phenomenon: The interface prompts
The tool call is not supported. Cause: Theplugin_mcp_enabledconfiguration is not enabled, or the MCP tool for carbon steel market quotations is not bound in the platform, resulting in the platform being unable to recognize available calling APIs.
How to confirm the configuration is complete
- Use the platform's tool debugging interface to enter the carbon steel category code, specification parameters, and data type, initiate a test call, and check whether the returned fields match the preset
response_parse_schema. - View the tool calling history logs to confirm that the call frequency does not exceed the
tool_call_rate_limitsetting, and there are no current limiting related errors. - Check the platform's plugin management page to confirm that
plugin_mcp_enabledis in the enabled state, and the corresponding MCP tool for carbon steel market quotations has been bound. - Manually compare the returned unit price values with the official public quotation units to confirm that no unit conversion errors have occurred.
