What This Category's Data Looks Like
Carbon steel financing daily report data comes from domestic steel industry spot monitoring databases, regional steel market ledgers, and financing summary data from cooperating steel trading enterprises. The data is updated daily, and all updates finish before 3:00 AM local time on the same day. Data is returned in standard JSON array format. Each record includes fields such as transaction ID, steel grade, specification model, financing amount, financing date, storage address, and repayment period. Steel grades are mostly common carbon steel models such as Q235, Q355. Specifications cover categories including wire rods, plates, and profiles. Financing amount is denominated in Chinese Yuan. Repayment period is measured in calendar days.
Constraints Imposed on HTTP Interfaces and External Systems
The fixed daily update schedule requires interface requests to align with the data update rhythm. This avoids pulling incomplete temporary data too early, or lagging data by pulling too late. Structured data with multiple fields requires the interface to support filtering by dimensions such as financing date, steel grade, and specification. Otherwise, it cannot meet the precise query needs of business parties. Fixed field formats require external systems to strictly validate parameter formats during integration. This prevents parsing failures caused by field mismatches. The numeric type for large financing amounts requires the interface to handle large number serialization. This prevents precision loss that affects data accuracy.
How to Configure Parameters
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
REQUEST_CRON | 0 4 * * * | The carbon steel financing daily report finishes updating by 3:00 AM daily. Setting the request trigger to 4:00 AM daily ensures complete same-day data is pulled |
HTTP_REQUEST_TIMEOUT | 25 seconds | The carbon steel financing daily report interface typically responds within 15 seconds. 25 seconds covers common network fluctuation scenarios |
RETRY_MAX_ATTEMPTS | 2 | Sets retry times for temporary network failures, to avoid invalid repeated requests consuming system resources |
REQUIRED_FIELDS | ["financing_date", "steel_grade", "financing_amount"] | The core query fields for carbon steel financing scenarios are financing date, steel grade, and financing amount. Configuring required fields filters invalid requests |
AUTH_CONFIG | {"type": "api_key", "header": "X-API-Key"} | Using API key authentication complies with industry general specifications. Identity verification can be completed via FastGPT's key management module |
DATA_PARSE_STRATEGY | array_root | The carbon steel financing daily report returns JSON array format. Configuring as array_root directly maps interface returned data to knowledge base entries |
The parameter values provided on this page are common recommended 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 Mistakes
- Phenomenon: Returns
401 Unauthorizedstatus code after calling the interface, with a prompt indicating no access permission. Cause: The API key parameter inAUTH_CONFIGis not configured correctly, or the key has expired and is no longer valid. - Phenomenon: The
specificationfield in pulled financing daily report data is empty. Cause: This field is not included inREQUIRED_FIELDS, or the name of the specification field returned by the third-party interface does not match the preset value, leading to data parsing failure. - Phenomenon: Returns
Model response emptyerror after calling the interface. Cause: The request interval is set too short, resulting in repeated pulls of empty temporary data, or filter fields are not configured correctly leading to empty returned data.
How to Confirm Successful Configuration
- View FastGPT's interface call logs to confirm that the request trigger time matches the update time of the carbon steel financing daily report.
- Manually trigger an interface request, and check whether the returned JSON data contains core business fields.
- Verify the authorization configuration: use the configured API key to initiate a request, and confirm that no permission-related status codes are returned.
- View the knowledge base synchronization records to confirm that the pulled carbon steel financing daily report data has been successfully synchronized to the target knowledge base.
