HTTP Interfaces and External Systems for Minor Metal

What the data for this category looks like

Minor metal data comes from two main sources: public statistics from domestic non-ferrous metal industry associations and real-time quotes from spot electronic trading platforms. Data is updated on three schedules:

Spot transaction prices each trading day
Industry inventory data monthly
Downstream application proportion data quarterly

Each data entry includes these fields: product name, origin identifier, daily trading price range, total inventory volume, and major downstream application areas. Price units are yuan per metric ton, and inventory units are metric tons. Data is structured in table format. It can be directly used for structured reference and display of minor metal investment marketing materials in financial and wealth management scenarios.

What constraints do these characteristics impose on HTTP interfaces and external system integration

Minor metal data’s real-time and multi-dimensional structured nature creates clear constraints for HTTP interface and external system integration. Spot data’s high-frequency update requirement means interfaces must support 2-3 concurrent requests per second. Cache durations should not be excessive. Multi-field structured data formats require interfaces to support specifying returned fields. This avoids redundant data transmission that increases system load. Scattered data source origins require external systems to configure unified data format verification rules during connection. This integrates results from multiple interfaces. Varied product types and differing parameters between products require interfaces to support filtering by product. This ensures marketing content accurately matches target categories. Customer acquisition and marketing needs for financial and wealth management users require interfaces to return data adapted to material splitting and display formats. This avoids missing fields or format confusion, and lets marketing content quickly adapt to different customer acquisition channels.

How to set configurations

Configuration Item	Recommended Value	Rationale
`api_request_timeout`	`30 seconds`	Minor metal data source interface response times typically range from 10-25 seconds, so 30 seconds covers most normal requests
`dataset_sync_interval`	`5 minutes`	Spot transaction prices are updated each trading day, a 5-minute sync interval ensures the timeliness of marketing content
`api_return_fields`	`["metal_name", "trading_price", "stock_volume", "downstream_industries"]`	Marketing content only requires core business fields, this configuration reduces data transmission volume and improves interface performance
`parse_chunk_size`	`800–1200 characters`	Minor metal marketing materials typically include product parameters and application scenarios, this segment length adapts to natural reading rhythm
`external_api_auth_type`	`API_KEY`	External data sources require identity verification, the API_KEY method is simple to configure and complies with industry security standards
`batch_request_concurrency`	`First 3 requests`	Most minor metal spot trading platform interface rate limits are 2-3 requests per second, this configuration avoids requests being blocked

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, so specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.

Three common misconfigurations

Calling the POST /api/core/dataset interface returns a 400 Bad Request error when structured fields for minor metal data are not passed correctly, preventing the system from recognizing valid content.
Frequent ETIMEDOUT errors occur during batch synchronization of minor metal marketing content when the configured request timeout duration is shorter than the actual response time of the data source interface, leading to forced request termination.
Marketing content returned by the chat interface omits source text. This happens when the return_source_detail parameter is not enabled, or the synchronized knowledge base is not associated with the original minor metal data documents.

How to confirm configuration is correct

Execute a test curl request. Check if returned fields include all items in the configured api_return_fields list, to confirm the interface returns data as expected.
Review the external system's request logs. Confirm synchronization frequency matches the dataset_sync_interval setting, and there are no frequent rate limit errors or timeout records.
Initiate a batch upload test. Check if the segment length of imported knowledge base content matches the parse_chunk_size configuration, to ensure reasonable material splitting.
Initiate a chat test. Confirm returned results include source text, and the return_source_detail parameter is enabled correctly.

Question material comes from public community discussions. Configuration values are common starting points and should be measured against your own samples. Verified on 2026-09-14.
