HTTP Interfaces and External Systems for Paper Industry

What the data for this category looks like

Paper industry research report data comes from three main sources: public data released by domestic light manufacturing industry associations, regular announcements of listed paper enterprises, and public research reports from third-party industry consulting institutions. Update cadence varies by report type:

Full industry panorama reports (quarterly, semi-annual, annual) have an update cycle of 1 to 3 months.
Monthly monitoring reports for segmented categories have an update cycle of 1 month.
Enterprise tracking research reports update synchronously with enterprise announcement releases.

Typical document structure includes industry macro environment analysis, raw material supply and demand data, production and sales status of segmented categories, operating data of leading enterprises, and future trend projections. Fields included in the data are: report publishing institution, release date, core covered categories, raw material cost proportion value, monthly production capacity value, finished paper ex-factory price value. Production capacity values use ten thousand tons as the unit. Price values use yuan per ton as the unit. After conversion to plain text, the length of a single research report typically ranges from several thousand to tens of thousands of characters.

Constraints on HTTP Interfaces and External Systems

The characteristics of paper industry research reports—multiple update cycles, wide range of segmented categories, fields with specific units, and long text—impose multiple constraints on HTTP interfaces and external systems:

Multiple update cycles require interfaces to support incremental data retrieval by release time range. This avoids repeated processing of old documents, and adapts to synchronization logic for data sources with different cycles.
Fields include numerical data with specific units. External system integration requires unified unit conversion logic, to ensure that production capacity and price data from different sources can be correctly integrated.
Single research reports have large text lengths. Interface request body size limits and parsing timeout settings must adapt to long text processing requirements, to avoid request truncation or interruption.
Wide coverage of segmented categories requires interfaces to support filtering parameters by category, covered enterprises, and other dimensions. This enables precise retrieval.
Research reports contain large amounts of structured table data. External system interface parsing configurations must support structured extraction of table content, to improve retrieval accuracy.

How to Configure Settings

Configuration Item	Recommended Setting	Rationale
`maxContext`	`8000–12000 characters`	The plain text length of a single converted paper industry research report typically ranges from several thousand to tens of thousands of characters. This setting adapts to long text context storage and processing requirements
`recallTopK`	`Top 10–15 results`	The paper industry has a large number of segmented categories. Sufficient recall results are needed to cover retrieval requirements for different categories
`PARSE_FILE_TIMEOUT_SECONDS`	`120 seconds`	Structured parsing and table extraction for long text research reports require extended processing time. This setting prevents parsing interruptions mid-process
`filterByCategory`	`Enabled and specify packaging paper/cultural paper/boxboard paper`	Significant differences exist between segmented categories in the paper industry. Precise filtering eliminates interference from unrelated category data
`apiRequestTimeout`	`60 seconds`	Aggregating and retrieving research reports from multiple data sources requires sufficient request duration to complete data synchronization and integration
`UPLOAD_FILE_MAX_SIZE`	`50 MB`	A single complete paper industry research report PDF typically contains 10–30 pages, with a post-conversion size ranging from 10–50 MB

The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.

Three Common Configuration Errors

Calling the /api/v1/chat/completions interface returns a 403 Forbidden status code or cross-origin error. Cause: No interface cross-origin whitelist is configured, and API keys are directly exposed on the frontend, leading to permission verification failure.
A large number of research reports from unrelated categories appear in retrieval results, and the number of recalled results does not match the configured value. Cause: The filterByCategory parameter is not set correctly, or no paper industry segmented category filtering conditions are specified, resulting in failure to filter data by specific domain.
Parsing research reports returns a 504 Gateway Timeout status code, or interface requests are interrupted prematurely. Cause: The PARSE_FILE_TIMEOUT_SECONDS configuration is not set to a duration adapted to long text parsing, leading to parsing timeout.

How to Verify Correct Configuration

Initiate an interface request filtered by a specified release date range. Check that returned results only include paper industry research reports within the corresponding time interval. Confirm that the time range and category filtering parameter configurations are effective.
Upload a standard paper industry research report PDF file. Check that the parsed results returned by the interface include exclusive fields such as raw material costs, production capacity, and ex-factory prices. Confirm that the long text processing configuration adapts to current business requirements.
Call the multi-user chat record query interface, and initiate requests using different API keys. Check that chat records corresponding to each key are isolated from each other. Confirm that multi-user permission configurations are correct.
Initiate a retrieval request containing keywords for paper industry segmented categories. Check that the number of returned recall results matches the preset configuration. Confirm that the recall parameter configurations are effective.
