What the Data for This Category Looks Like
Data sources for precious metals research reports include public market data from domestic precious metals exchanges, securities firm industry reports, and professional precious metals information platforms. Market-related reports update in real time during daily trading sessions. Industry supply and demand in-depth reports update weekly. Document structures include product identifiers, transaction prices, supply and demand indicators, and policy interpretation modules. Fields include priced values with units (yuan/gram, US dollars per ounce), inventory measured in tons, price change percentages, plus metadata such as publishing organization and publication time. Research report content often includes multiple sets of industry data tables. Some in-depth reports include historical price trend charts.
Constraints for HTTP Interfaces and External System Integration
The data characteristics of precious metals research reports impose multiple constraints on HTTP interface and external system integration. Real-time market reports have high update frequencies. Interfaces must support high-frequency calls or incremental push mechanisms to prevent stale cached data. Price and inventory fields use multiple units. Interfaces must support unit specification via parameters to adapt to display needs of different external systems. Structured report content requires interfaces to return standardized field mappings. This reduces cleaning costs for external systems. Aggregation across multiple data sources requires interfaces to support configuration items for merging data from multiple sources. This handles field differences across data sources.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
recall_count | 3-8 entries | Each precious metals research report focuses on a single product. A small number of recalled entries covers core information, avoiding redundant content that interferes with retrieval results |
similarity_threshold | 0.75-0.85 | Precious metals research reports contain many professional terms. A threshold that is too low introduces irrelevant reports, while a threshold that is too high may miss highly relevant content |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Single in-depth precious metals research reports often include multiple sets of industry data tables. Parsing time is significantly longer than that for general documents |
UPLOAD_FILE_MAX_SIZE | 20 MB | The file size of a complete single precious metals industry research report usually does not exceed this threshold, supporting batch upload requirements |
external_return_unit | Specified via request parameters | Precious metals data uses multiple units such as yuan/gram and US dollars per ounce. External systems must be able to specify return units |
batch_request_rate_limit | 6 requests per minute | Most precious metals data source APIs have call rate limits. This configuration avoids triggering rate limit errors |
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 specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Configuration Errors
- Symptom: Target precious metals product cannot be specified via query parameters when calling the interface. Retrieval results do not match the specified product. Cause: Global variable binding rules are not configured in interface parameters, and product filtering conditions are not passed correctly.
- Symptom: After setting
recall_countto 6, the number of research reports returned by the interface is fewer than 6. Cause: The return upper limit configuration of the data source is not adjusted, or the merging logic for multi-source data aggregation is not enabled. Single-source data cannot meet the recall count requirement. - Symptom: The original research report text returned by the interface contains many redundant punctuation marks, causing failure of external system SQL parsing. Cause: The structured cleaning switch for research report content is not enabled. Raw formatted document content is returned directly.
How to Verify Proper Configuration
- Call the interface with parameters for a specified precious metals product. Confirm returned results only include research report content for that product.
- Adjust the
recall_countconfiguration. Call the interface to count returned research reports, and confirm the number matches the configured value. - Pass parameters for a specified unit. Confirm returned price, inventory and other fields use the specified unit.
- Call the interface multiple times consecutively. Check if the
429 Too Many Requestsstatus code is triggered, to confirm the rate limit configuration is active.
