What Data for This Category Looks Like
Chemical raw material marketing content data mainly comes from national chemical product trading platforms, official APIs of manufacturing enterprises, and industry index databases. It serves scenarios such as supply chain finance for financial institutions and marketing for wealth advisors. Spot quote data updates daily. Inventory and capacity data updates every 3 to 7 days. Import and export monitoring data updates monthly. Most documents are in structured JSON or CSV format. Core fields include CAS registry number, product name, manufacturer, specification model, current quote, inventory balance, and update time. Specification model fields often note packaging units and batch sizes, such as "25kg/drum" or "1000kg/big bag". Quote units are mostly CNY per kilogram or CNY per ton.
Constraints Imposed by These Characteristics on HTTP Interfaces and External Systems
The data characteristics of chemical raw materials impose clear constraints on HTTP interfaces and external systems used in financial scenarios. CAS registry number acts as a unique identifier, so interface requests must support matching by CAS number or exact product name. Otherwise, duplicate or mismatched marketing materials will be returned, affecting the accuracy of customer outreach for financial institutions. Spot quote data updates daily and returns many entries per request. Interfaces must limit the maximum data volume per response to avoid request or response size limit errors, ensuring stable operation of financial systems. Diversity of specifications and units requires interfaces to provide standardized unit mapping fields or support unit conversion parameters, reducing parsing and display costs for financial systems. Inventory and import/export data have longer update cycles. Interfaces must support incremental pulling by update time, reducing invalid full requests and improving synchronization efficiency for financial systems.
How to Set Configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
AIPROXY_API_ENDPOINT | Official API address of the target chemical data platform, such as https://api.chemical-trade.com/v1 | Corresponds to the public interface address of the external data source, ensuring normal access by financial systems |
AIPROXY_API_TOKEN | Exclusive access key applied for from the chemical data platform | Used for interface identity verification, preventing failure to obtain marketing data due to unauthorized access |
HTTP_REQUEST_TIMEOUT | 30 seconds | Chemical raw material interfaces return large volumes of data, so sufficient time is reserved for data pulling and parsing |
MAX_RESPONSE_BODY_SIZE | 100 MB | The volume of spot quote data pulled in a single request is high, limiting response size to avoid triggering 413 errors |
INCREMENTAL_SYNC_INTERVAL | 86400 seconds | Spot quotes update daily, and daily incremental synchronization ensures the timeliness of financial marketing content |
UNIT_MAPPING_ENABLE | enabled | Standardize packaging and quote units to meet the unified display requirements of financial systems |
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 case-by-case analysis. Testing on internal samples is recommended before finalizing settings.
Three Common Mistakes
- Calling the interface returns a 413 Request Entity Too Large error, causing marketing content synchronization to interrupt. The cause is that the volume of chemical raw material data pulled in a single request exceeds the response body size limit of the interface or external system.
- The interface returns a 401 Unauthorized error, or returns empty marketing content data, making it impossible to provide accurate raw material information for financial customers. The cause is that the configured
AIPROXY_API_TOKENis invalid, and identity verification for the external interface has failed. - The raw material quote unit displayed by the external system does not match the requirements for financial publicity, resulting in numerical deviations. The cause is that unit mapping configuration is not enabled, and non-standardized unit fields returned by the original interface are used directly.
How to Verify Successful Configuration
- Initiate a small-scale test request to verify that the configured
AIPROXY_API_ENDPOINTcan connect normally and return structured data meeting financial marketing requirements. - After configuring
MAX_RESPONSE_BODY_SIZE, initiate a test request containing multiple spot data entries to confirm that response body size limit errors are not triggered, ensuring stable synchronization processes. - Review the synchronized marketing content fields to confirm that core identifiers and business fields are complete, and unit mapping meets the unified requirements of financial publicity.
- Trigger an incremental synchronization task to confirm that only data sources with update times within the preset cycle are pulled, avoiding full repeated pulls that affect financial system performance.
