HTTP Interfaces and External Systems for Refractory

What the data for this category looks like

Data for the refractory materials financing daily report is sourced from public financing filings from domestic refractory industry associations, private placement and supply chain financing announcements disclosed by enterprises, and transaction records from third-party bulk commodity financing monitoring platforms. The update schedule follows a T+1 working day cadence: summary and release of the previous day’s data is completed by 18:00 each working day. Data is provided in structured JSON format. Each single record includes these fields:

Unified social credit code of the enterprise
Main refractory product category
Financing amount (unit: ten thousand yuan)
Financing term (unit: month)
Financing channel type
Announcement release date
Affiliated province, plus additional relevant fields

Batch interfaces return an array containing multiple records.

Constraints imposed on HTTP interfaces and external systems

The following constraints apply to HTTP interfaces and external systems due to data characteristics:

Interfaces require dedicated authentication parameters to prevent unauthorized access, as data includes sensitive information such as enterprise unified social credit codes.
Scheduled pull tasks for external systems must align with working day trigger windows, to avoid pulling incomplete updated datasets, given the T+1 working day update cadence.
Interfaces must support filtering by category keywords, to reduce secondary cleaning overhead for external systems, as fields include detailed main refractory product categories.
Interface returned values must retain consistent units, to avoid parsing conflicts with financing data from other categories, as the default unit for financing amounts is ten thousand yuan.
Interfaces must support pagination parameters, to adapt to pull capacity requirements of different external systems, as batch responses use an array structure.

Configuration guidelines

Configuration Item	Recommended Setting	Rationale
`API_KEY`	`Exclusive key agreed with the data provider`	Used for interface authentication, to protect sensitive enterprise and financing data from the refractory materials financing daily report
`CRON_EXPRESSION`	`0 19 * * 1-5`	Matches the 19:00 working day update cadence, to pull complete previous day’s financing daily report data
`BATCH_SIZE`	`150 records per request`	Adapts to the return capacity of batch interfaces, balancing pull efficiency and request stability
`REQUEST_TIMEOUT`	`30 seconds`	Covers normal interface response durations, to avoid timeout errors triggered by fluctuations in data volume
`FILTER_RULE`	`Main category includes refractory material keywords`	Filters non-refractory financing records, reducing secondary cleaning overhead for external systems
`DATA_UNIT_POLICY`	`Retain original ten thousand yuan unit`	Matches the default unit of the financing amount field in the daily report, unifying parsing logic for external systems

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 case-by-case analysis. It is recommended to test on your own samples before finalizing settings.

Three common configuration mistakes

Interface calls return a 413 Request Entity Too Large status code. This occurs when no reasonable BATCH_SIZE parameter is configured, and the volume of financing daily report data pulled in a single request exceeds the maximum request body limit allowed by the interface.
A URIError: URI malformed error is triggered. This happens when URL encoding is not applied to enterprise names or main product category fields that contain special characters in the financing daily report, leading to incorrect URI parameter formatting for interface requests.
External interface calls fail during local deployment, with an authentication failure prompt. This is caused by incorrect configuration of the AIPROXY_API_ENDPOINT and AIPROXY_API_TOKEN parameters, which do not match the interface address and key provided by the data provider.

How to confirm correct configuration

Initiate a single interface request to check whether returned field units and main product categories match the characteristics of the refractory materials financing daily report, and adjust corresponding configuration items until alignment is achieved.
Review execution logs for the scheduled pull task to confirm that pulls are triggered at the specified time on working days, and adjust the CRON_EXPRESSION configuration until it matches the update cadence.
Construct a test request containing special characters to verify that the interface request has no formatting errors, and adjust URL encoding logic or authentication parameters until normal responses are received.
Adjust the single pull quantity threshold to verify that the interface returns a normal status code, and adjust the BATCH_SIZE configuration until it meets interface limits.

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.
