What data for this category looks like
Energy metals data is primarily sourced from industry association public reports, domestic futures exchange market interfaces, regular disclosures from mining and smelting enterprises, and third-party bulk commodity information platforms. Update frequencies vary widely: spot prices are updated every 15 minutes, monthly supply and demand data is updated monthly, and enterprise production capacity dynamics are released as needed. Individual data entries include variety code, Chinese name, origin classification, spot quote, futures settlement price, inventory balance, supply and demand forecast value, and data update timestamp. Units follow standard bulk commodity standards such as yuan/ton, ton, and ten thousand tons.
Constraints on HTTP interfaces and external system pipelines
The multi-source, varied update frequency characteristics of energy metals data create multiple constraints for HTTP interfaces and external system pipelines. High-frequency spot data requires interfaces to support 15-minute level polling or active push, otherwise real-time marketing material generation cannot be supported. Field differences across multiple data sources require a pre-built unified conversion interface to align core fields such as variety codes and units. The total volume of full-category data per batch is large, so interfaces must support pagination pull parameters to avoid single-request timeouts. Marketing content requires association with multi-dimensional data, so external systems must support linked calls across multiple interfaces and retain data traceability identifiers for content verification.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
external_api_timeout | 300 seconds | Most external APIs related to energy metals have peak response times within 200 seconds; 300 seconds covers delays caused by network fluctuations |
batch_sync_limit | 500 items/request | Adapts to bulk synchronization requirements for full-category and segmented energy metal varieties, preventing third-party interfaces from blocking single requests due to excessive data volume |
field_unify_strategy | Enforce alignment with standard bulk commodity units | Resolves inconsistent unit returns across multiple data sources, ensuring unified units for fields such as prices and inventory in marketing content |
polling_trigger_rule | Validate by data update timestamp | Avoids repeated pulling of already synchronized energy metal data, reducing interface call frequency |
external_api_auth_mode | API_KEY authentication | Matches the authentication standards of most bulk commodity information and exchange interfaces, simplifying access configuration |
response_parsing_mode | Structured JSON extraction | Adapts to the return formats of most energy metal data interfaces, allowing direct extraction of core fields for marketing content generation |
The parameter values provided on this page are conventional recommendations used as starting points for configuration. Actual values are affected by material forms, data volume, and business rules. Specific issues require individual analysis, and it is recommended to test against your own samples before finalizing.
Three common configuration errors
- Phenomenon: After calling the bulk data synchronization interface, no local mapping ID for energy metal data is obtained, making local data association impossible. Cause: No extraction rule for interface return fields is configured, and the parameter path for the returned ID is not specified.
- Phenomenon: External interface calls frequently trigger
504 Gateway Timeouterrors, interrupting synchronization tasks. Cause: Theexternal_api_timeoutconfiguration is not adjusted, and the default timeout period is insufficient to cover the pull delay of full-category energy metal data. - Phenomenon: After restarting the external system container, FastGPT cannot reconnect to the interface, and the log shows connection refused. Cause: The interface address is configured with the container's temporary IP address, and a fixed authentication domain or dynamically resolved address is not used.
How to confirm the configuration is complete
- Perform a single small-batch energy metal data synchronization test, check whether the returned results include expected core fields such as variety codes and quotes, and confirm that units are unified.
- View interface call logs to confirm that request intervals comply with configured validation rules, and there are no repeated pulls of already synchronized data.
- Modify the temporary address configuration of the external system, test whether the interface can reconnect normally, and confirm that the authentication configuration is not bound to a fixed temporary IP.
- Trigger a preset data update threshold, confirm that synchronization requests are triggered normally, and there are no missing updates for target data.
