What this category of data looks like
Power yield and market data primarily comes from public APIs of regional power trading centers, official daily reports released by provincial energy regulatory agencies, and public operational data of power business entities. The data update schedule is as follows: intraday market data is updated within 24 hours after market close, and monthly summary data is released within 5 working days of the following month. Each data entry includes fields such as trading time period, trading entity type, settlement price, benchmark electricity price, and trading volume. The unit standards for these fields are uniformly yuan/megawatt-hour and megawatt-hour, with no additional percentage-based metrics. The core associated fields for each entry are trading region and trading type. Significant differences in benchmark electricity prices exist across different regions.
Constraints imposed by these characteristics on tool calling and plugins
APIs for regional power trading data require exclusive authentication, so tool calling plugins must be configured with valid authentication parameters, otherwise compliant data cannot be retrieved. Data updates follow a fixed schedule, so tool trigger timing must align with the update cycle to avoid calling outdated data that has not completed updating. Field units and association requirements have specific rules: both settlement price and benchmark electricity price use yuan/megawatt-hour as their unit, and the trading region parameter must be included to complete yield calculation. As such, plugins must support multi-field linkage validation and trading region parameter binding. Data source interfaces vary across different regions, so plugins must support dynamic switching of regional configurations to adapt to data acquisition needs for different business scenarios.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
plugin_api_key | Exclusive API key for the target regional power trading center | Public APIs of regional power trading centers require authentication, and binding an exclusive key allows retrieval of compliant data |
plugin_request_timeout | 30 seconds | Responses from power trading data interfaces typically take 10-25 seconds; adding a 5-second buffer prevents timeout errors |
tool_trigger_cron | 0 3 * * * | Daily power market data is updated within 24 hours after market close; triggering at 3 AM daily ensures access to the latest data |
field_unit_conversion | Enabled, convert yuan/megawatt-hour to yuan/kilowatt-hour | Discrepancies exist between the system's default units and commonly used business units; conversion adapts to downstream display requirements |
required_tool_fields | ["settlement_price", "benchmark_price", "trade_region"] | At least two price fields and the trading region parameter are required for power yield calculation; calculation cannot be completed if any are missing |
plugin_max_retries | 2 retries | Power data interfaces occasionally experience fluctuations; two retries cover most temporary failures |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Symptom: After the plugin exposes a public network port, the backend generates a large number of 401 Unauthorized request logs. Cause: No validation rules for
plugin_api_keyare configured, and exposing the port directly allows unauthorized access. - Symptom: Tool calls return an error message stating "missing required fields" and cannot generate yield calculation results. Cause:
required_tool_fieldsis not set in the configuration, and the trading region parameter is not passed during the call. - Symptom: During two consecutive tool calls, the calculation result from the first call is not carried over to the second request, causing each calculation to require repeated input of baseline data. Cause: Context passing configuration for tool calls is not enabled, and parameters from individual calls are not retained for subsequent requests.
How to Verify Successful Configuration
- Call the tool's test interface, check if the returned fields include the configured required items, and verify that the units match commonly used business formats.
- Review the tool call history logs to confirm that trigger times align with the
tool_trigger_cronsetting, and that no requests are sent during the data update cycle. - Simulate two consecutive tool calls, check if the second call can retrieve the calculation result from the first call as a context parameter.
- Check the plugin's port configuration to confirm that access is restricted to specified network segments or IP addresses, and that the port is not exposed publicly without protection.
