HTTP Interfaces and External Systems for Air Pollution

What this category's data looks like

Air pollution control financing daily report data comes from provincial ecological environment department air pollution prevention project registration databases, local financial supervision bureau green financing ledgers, and publicly available project announcements from industry associations. Updates run daily. The previous day’s data is aggregated each early morning. Each record includes these fields: project name, administrative region, air pollution control type (such as VOCs emission reduction, dust control, boiler renovation), financing amount, financing subject, fund provider, and registration date. Field rules: Financing amount uses ten thousand yuan as the unit. Administrative regions are precise to district and county level. Registration dates follow the YYYY-MM-DD format.

Constraints for HTTP interfaces and external systems

Multiple data sources mean the interface must support connecting to platforms including ecological environment and financial supervision. Configure multi-request address aggregation logic. Daily updates mean scheduled sync task triggers must match the data update cycle. This prevents repeated data pulling or delayed synchronization. Enumerated governance type fields require interface return values to pass validity checks. This stops invalid data from entering the system. Unified unit requirements mean external system connections must complete ten thousand yuan to yuan unit conversion, or configure local field unit mapping rules. Region hierarchical fields require the interface to support filter queries by administrative region. This supports data filtering for different scenarios.

How to set configurations

Configuration Item	Recommended Value	Rationale
`Scheduled Sync Interval`	`86400 seconds`	Matches the daily update cycle of air pollution control financing daily reports, avoids repeated pulling of previous day’s data
`HTTP Request Timeout`	`30 seconds`	Most external data source interface response times fall between 10-25 seconds, reserves reasonable buffer time
`Field Validation Rules`	`Enumerated value matching + non-negative numeric validation`	Governance types belong to a fixed enumerated set, financing amounts must be non-negative values, filters out invalid records
`Concurrent Request Limit for Multiple Sources`	`2–4 concurrent requests`	Avoids triggering external platform rate limiting mechanisms by sending too many requests simultaneously
`Request Retry Count`	`3 retries`	Addresses single request failures caused by network fluctuations, reduces sync task failure probability
`Result Date Filter Threshold`	`Last 7 days`	Focuses on currently valid financing projects, avoids historical data occupying storage space

The parameter values provided on this page are general recommendations to serve as a starting point for configuration. Actual values are affected by data format, data volume, and business rules. Each scenario requires individual analysis. It is recommended to test on your own samples before finalizing settings.

Three Common Configuration Mistakes

A 429 Too Many Requests error occurs when calling external interfaces. No reasonable concurrent request limit for multiple sources is set. Frequent data pulling triggers external platform rate limiting rules.
Some project financing amount fields are empty after synchronization. No field validation rules are configured, cross-platform field name differences are not handled, or invalid records without marked financing amounts are not filtered.
Bound custom HTTP interfaces are not called after preset keywords are triggered. The "Call external interface after interception" switch is not enabled in keyword interception configuration, or the custom interface callback address is not filled correctly.

How to confirm configuration is complete

Use the FastGPT built-in interface debugging tool, enter the target data source’s interface address, and verify if returned fields match local configuration mappings.
Check scheduled task execution logs to confirm daily sync tasks run successfully, with no Request timed out or Insufficient permissions errors.
Trigger preset keyword tests to verify bound custom HTTP interfaces are called, and returned results meet expectations.
Cross-check the synchronized dataset to confirm it only includes valid air pollution control financing projects from the last 7 days, with field units uniformly set to ten thousand yuan.
