What the data for this category looks like
Coke is a segmented coal product. Marketing content for financial scenarios relies on accurate real-time industry data. Data sources include the China Coal Industry Association, coastal port spot trading platforms, and the Dalian Commodity Exchange.
Update frequencies vary: spot quotes update daily, futures settlement prices update after daily market close, and weekly inventory data is released every Wednesday.
Data is presented in structured tables, with required fields: product identifier, specification parameters, transaction type, statistical value, statistical cycle. Specification parameters cover indicators such as ash content, sulfur content, and particle size. Prices use yuan per ton as the unit, inventories use ten thousand tons as the unit. Each coke specification has independent price and inventory data entries.
What constraints these characteristics impose on HTTP interfaces and external systems
Coke’s multi-specification attribute requires HTTP interfaces to support multi-parameter filtering. Specification fields such as ash content and particle size must be passed to obtain accurate data. External system calls therefore require multi-dimensional query parameters.
Differences in update frequencies across data types require setting different polling intervals for different interfaces. For example, poll the spot interface daily and the inventory interface weekly. This avoids excessive calls or expired data.
Clear units are required for prices and inventories. Interface responses must include unit fields, otherwise data display in marketing content will cause confusion. Additionally, coke marketing content for financial scenarios requires association with regional transaction data. Interfaces must support regional dimension queries. Cases where futures data is empty during market closures must be handled to avoid abnormal content generation.
How to configure settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
HTTP_REQUEST_TIMEOUT | 600 seconds | Batch multi-specification coke data queries have long response times. The default timeout is insufficient to complete full requests |
RETRY_MAX_TIMES | 2–3 attempts | Spot interfaces occasionally return temporary errors due to exchange data synchronization delays. Retries reduce request failure rates |
VAR_PARSE_MODE | {{}} Compatibility Mode | Adapts to the variable parsing rules of version V4.8.18-FIX2. Correctly concatenates multi-specification coke parameters, replacing the older / mode |
MODEL_SELECT_SCOPE | Configured custom models | Supports selecting custom models adapted for coke industry analysis when generating marketing content |
TOKEN_PERMISSION_CHECK | Enabled | Verifies token permissions for external interface calls, preventing 403 access denied errors |
PAGE_SIZE | Top 20 entries | Limits the number of data entries returned per page. Prevents overload from multi-specification coke data from slowing marketing content generation |
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 individual analysis. It is recommended to test on your own samples before finalizing settings.
Three common configuration errors
- Symptom: External coke data interface calls return a 403 status code, with a prompt that the token does not have permission to use the resource. Cause: The dedicated access permission for the coke data interface is not bound in the external interface configuration. Only a base token is configured, with no access scope added for the corresponding interface.
- Symptom: Using
/format to reference variables in HTTP nodes causes multi-specification coke parameters to fail to concatenate correctly. Missing parameters appear in generated marketing content. Cause:{{}} Compatibility Modeis not enabled. Older variable parsing rules cannot handle multi-segment nested product parameters. This issue exists in versions prior to V4.8.18-FIX2. - Symptom: Coke price fields in generated marketing content are empty or display expired data. Cause: Correct polling update frequencies are not configured based on data type. Cached coke data is not refreshed to pull the latest spot or futures quotes.
How to confirm correct configuration
- Access the FastGPT HTTP node test panel. Pass parameters including coke specifications and region, then call the test interface. Check that the returned JSON data includes correct fields such as price and origin, and that units match the configured requirements.
- Enter a prompt containing coke parameters in a test conversation. Verify that variables in
{{}}format are correctly replaced with corresponding parameters, and that no missing parameters appear in generated content. - Review system operation logs. Confirm that tokens for external interface calls have passed permission checks, and no 403 error logs are present.
- Wait for one polling cycle. Check that coke data associated with marketing content has updated to the latest spot or futures prices, confirming normal data synchronization.
