HTTP Interfaces and External Systems for Minor Metal

What the Data for This Category Looks Like

Minor metal research report data primarily comes from official reports publicly disclosed by domestic non-ferrous metal industry associations, upstream mining enterprises, and third-party professional metal information platforms. Data update cadence falls into three categories: spot price data is updated daily, industry dynamic weekly reports are updated weekly, and in-depth supply and demand analysis reports are updated monthly. The document structure of a single research report includes fields such as category basic information, spot and futures price ranges, inventory tons, supply and demand balance sheets, policy summaries, and more. Price fields mostly use yuan/ton or US dollars/ton as units, inventory fields use tons as units, and some research reports include grade percentage parameters.

Constraints Imposed on HTTP Interfaces and External Systems

The multi-tiered update cadence of minor metal research reports requires interfaces to support flexible call frequency configuration, to adapt to pull cycles for daily, weekly, and monthly data. The size of individual research reports varies widely, with in-depth reports reaching thousands of words, which places higher requirements on HTTP request timeout settings. The multi-category parallel data structure requires interface parameters to support specifying specific minor metal categories, to avoid confusion across category data. Price and inventory fields use different units, which require unified format conversion after interface returns, otherwise downstream parsing exceptions will occur. Most upstream information interfaces have call current limiting rules, which require matching corresponding frequency limit configurations.

How to Set Configurations

Configuration Item	Recommended Setting	Rationale
`timeout`	`600 seconds`	Minor metal in-depth research reports have a large word count, and upstream interfaces may have delayed returns of batch data. 600 seconds covers the complete request cycle
`retryCount`	`2–3 times`	Spot price interfaces are updated frequently. A small number of retries can offset temporary network fluctuations and avoid interrupting data synchronization
`headers.Authorization`	`Include a fixed Bearer token`	Match the identity verification requirements of upstream research report interfaces, to avoid `401 Unauthorized` errors
`fieldMapping`	`Split mapping by category`	A single research report contains multi-category data. The `metal_type` field must be bound to the corresponding research report content to avoid field coverage conflicts
`rateLimit`	`10 requests/minute`	Most minor metal upstream information interfaces have call frequency limits, which must match official current limiting rules
`responseParseMode`	`Segmented parsing`	Research report documents are too long. Segmented parsing adapts to FastGPT's context window limits

The parameter values provided on this page are conventional recommendations used as a starting point 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 Misconfigurations

Symptom: HTTP request returns 401 Unauthorized status code, and research report data cannot be pulled. Cause: The headers.Authorization field is not configured correctly, or the upstream interface token has expired and has not been updated.
Symptom: Only partial category data is returned when pulling research reports in batches, and the remaining fields are empty. Cause: fieldMapping is not configured to split mapping by category, leading to multi-category data coverage conflicts.
Symptom: HTTP request times out and returns 504 Gateway Timeout. Cause: The timeout setting is not long enough, and does not adapt to the large-volume data return of minor metal in-depth research reports.

How to Confirm Proper Configuration

Initiate a single HTTP request, check that the returned research report data includes the specified minor metal's metal_name and price fields, and the units match expected values.
View the FastGPT log module, confirm that all request status codes are 200 OK, with no 401 or 504 errors.
Configure a batch pull task, check that the number of returned research reports matches the public data volume of the upstream interface.
Initiate multiple concurrent test requests, confirm that the interface does not trigger current limiting errors, and complies with the configured rateLimit rules.
