HTTP Interfaces and External Systems for Precious Metals

What Data for This Category Looks Like

Precious metals financial report data is primarily sourced from public disclosures of the Shanghai Gold Exchange, the London Bullion Market Association, and periodic reports of listed precious metals enterprises. The core update cadence follows quarterly financial reports, with monthly industry monitoring data synced concurrently. The document structure includes fields such as core category holdings, spot prices, inventory levels, revenue composition, and production costs. Holdings are measured in tons, prices in yuan per gram or US dollars per ounce, and revenue and costs in ten thousand yuan or hundred million yuan. Most field names include a category prefix to distinguish between different precious metal varieties.

Constraints Imposed on HTTP Interfaces and External Systems

The multi-variant fields, multi-unit systems, and periodic update characteristics of precious metals financial reports impose multiple constraints on HTTP interface and external system integration. Support filtering returned fields by precious metal variety, such as gold or silver, to meet the business dimension requirements of different enterprises. Support two common unit systems, and provide unit conversion parameters to eliminate secondary processing costs for external systems. Support pulling data across quarterly or monthly time ranges to match business analysis needs for different cycles. Provide pagination interfaces to adapt to scenarios with large volumes of financial report data, avoiding single return data overload that impacts external system stability.

Configuration Settings

Configuration Item	Recommended Setting	Rationale
`api_base_url`	`https://api.sge.com.cn/v1`	Corresponds to the public interface address of the official data source for precious metals financial reports, ensuring compliance of data sources
`request_timeout`	`30 seconds`	Precious metals financial reports have large data volumes; reserve sufficient request duration to avoid timeout interruptions
`parse_field_filter`	`["gold_holding", "silver_price", "quarter_revenue"]`	Only extract core fields required for financial report analysis, reducing the data processing load on external systems
`unit_conversion_switch`	`Enabled`	Adapts to the dual unit system of domestic yuan per gram and international US dollars per ounce for precious metals data
`data_pagination_size`	`100 items per page`	Balances interface return efficiency and data integrity, adapting to the pagination processing logic of most external systems
`file_upload_allowed_types`	`[".csv", ".xlsx"]`	Compatible with structured spreadsheet file formats commonly used for precious metals financial reports, supporting bulk data import

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, and it is recommended to test on your own samples before finalizing.

Three Common Configuration Mistakes

Issue: Interface calls return the error "Only support .txt, .m" format, and links returned from the knowledge base cannot be accessed. Cause: The allowed upload types for precious metals financial report files are not configured. Only generic text formats are enabled, and the .csv and .xlsx formats commonly used for structured financial reports are not included.
Issue: Interface requests return timeout errors, and external systems cannot pull complete financial report data. Cause: The request_timeout configuration is not adjusted to a duration adapted to the volume of precious metals financial report data. The default duration is insufficient, leading to request interruption.
Issue: Callback interface synchronization fails, and financial report data is not synchronized to the external system. Cause: The local debug address http://localhost:3000 is used as the callback address. This address cannot be accessed in production environments, resulting in synchronization failure.

How to Verify Proper Configuration

Call the configured api_base_url with the corresponding interface path appended. Check if the returned data includes core fields of precious metals financial reports, and verify that the field names match the preset parse_field_filter.
Upload a structured precious metals financial report test file. Check if the upload process completes normally without format errors.
Initiate a pagination request. Check if the returned data is split according to the data_pagination_size setting, with no single return data overload.
Trigger a unit conversion test. Compare the original data and the converted data units, and confirm that unit_conversion_switch is active.
