What the data for this category looks like
Data for infrastructure construction project financing daily reports comes from housing and urban-rural development department project filing systems, commercial bank credit management systems, and public project announcements from industry associations. The update frequency is once per business day. Each daily report document includes three core modules: basic project identification, financing details, and fund flow. Fields include: unified project number, project name, administrative division, total investment amount, finalized financing amount, full name of financing subject, cooperating financial institutions, loan date, and financing purpose. Amount fields use RMB ten thousand yuan as the unified unit. Date fields follow the ISO 8601 format.
What constraints these characteristics impose on tool calling and plugins
The multi-source data requirement means tool calling must be configured with cross-system API connection parameters. This enables real-time aggregation of three types of data: housing and urban-rural development filing data, bank credit data, and industry announcement data. The business day update frequency requires scheduled plugin calls to trigger only on business days. This avoids pulling non-updated data during non-working hours. The fixed field and unit requirements mean the plugin must include built-in unit validation logic for amount fields. It must force conversion of pulled amount data to RMB ten thousand yuan. The fixed document structure means the tool calling response parsing node must pre-set extraction rules for the three modules. This improves parsing accuracy.
How to configure the settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
CRON Expression | 0 30 9 * * 1-5 | Triggers at 09:30 every business day, matches the daily report update schedule |
Concurrent Request Limit | 2 | Connects three data sources simultaneously, avoids exceeding third-party interface rate limits |
Automatic Unit Conversion | Enabled | Some data sources have inconsistent amount field units, requires unified conversion to RMB ten thousand yuan |
Response Parsing Rule | Extract by category: basic project information, financing details, fund flow | Daily report document structure is fixed, categorized extraction improves field extraction accuracy |
API Call Timeout Threshold | 600 seconds | Multi-source data aggregation requires longer processing time, prevents task interruption mid-run |
Tool Call Termination Configuration | Automatically end the workflow after call completion | Prevents the workflow from occupying running resources indefinitely |
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 case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three common configuration errors
- Symptom: The tool call node triggers multiple times repeatedly, with identical API requests shown in logs. Cause: The CRON expression includes non-business day trigger rules, resulting in calls during non-working hours.
- Symptom: Third-party API calls return a 429 status code, with requests blocked due to rate limiting. Cause: The concurrent request limit is set too high, exceeding the rate limits of third-party data source interfaces.
- Symptom: No compatible third-party data source API can be found, requiring compliant alternative interfaces. Cause: Some data sources have access restrictions on their public APIs, and authorized interfaces must be obtained via official open platforms.
How to confirm successful configuration
- Check the tool call node's running logs, confirm that trigger times align with the 09:30 business day setting, with no non-business day call records.
- Initiate a manual call test, verify that the amount fields in the returned results are uniformly converted to RMB ten thousand yuan, and all preset fields contain valid content.
- Adjust the concurrent request limit to a higher value, confirm that no 429 status code is returned during calls, ensuring third-party rate limiting rules are not triggered.
- Run the full workflow, check that the workflow ends normally with no abnormally persistent running tasks.
