HTTP Interfaces and External Systems for Chemical

What this category's data looks like

Data for chemical pharmaceutical financing daily reports comes from publicly disclosed documents of the Shanghai, Shenzhen and Beijing Stock Exchanges, third-party medical industry investment and financing databases, and public information from industry associations. The update schedule follows a daily cycle: full financing events from the previous day are updated each day, and data verification for that day is completed and released the next day. Each data entry includes the full name of the target enterprise, financing round, financing amount (unit: ten thousand yuan or hundred million yuan), list of joint investors, financing completion date, affiliated chemical pharmaceutical segmented tracks such as API, innovative preparations, CDMO and others, latest valuation range, and original announcement link. Data fields must match standardized formats required by securities disclosure. Events with undisclosed valuations are marked as "undisclosed".

What constraints these characteristics impose on HTTP interfaces and external systems

Data for chemical pharmaceutical financing daily reports comes from multiple sources and has format differences across segmented tracks. This requires HTTP interfaces to support dynamic switching of multi-data source authentication parameters, and adapt to API key configurations for different third-party databases. Financing amount units mix ten thousand yuan and hundred million yuan, so the interface must include a built-in unit conversion parameter to standardize output to a standard unit. The daily update schedule requires the interface to be configured with a fixed scheduling cycle. Financing completion date and target enterprise name must be used as joint deduplication fields to avoid repeated data pulls. Events with undisclosed valuations generate empty fields, so the interface must be configured with empty field fault tolerance rules to prevent errors from missing required fields during calls. All public data source APIs use HTTPS protocol, so the interface must enable SSL certificate verification to avoid call failures caused by certificate anomalies.

How to configure

Configuration Item	Recommended Setting	Rationale
`request_method`	`GET`	Most public APIs for pharmaceutical investment and financing data sources use GET requests to pull data, which aligns with industry general standards
`auth_type`	`Bearer Token`	APIs from mainstream industry investment and financing databases use Bearer authentication, which fits the authentication logic of most data sources
`timeout_seconds`	`300 seconds`	Multi-source data pulling requires waiting for interface responses. A 300-second timeout setting covers response durations for most data sources
`duplicate_keys`	`["Financing Completion Date","Target Enterprise Name"]`	This combination uniquely identifies a single financing event, effectively avoiding repeated pulls and storage of identical data
`convert_unit_field`	`融资金额`	This field uses mixed units of ten thousand yuan and hundred million yuan. Configuring this parameter standardizes output to a standard unit
`ssl_verify`	`Enabled`	Public data source APIs all require HTTPS connections. Enabling SSL verification prevents call failures caused by certificate anomalies

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 individual analysis. It is recommended to test on your own samples before finalizing settings.

Three Common Configuration Mistakes

A 502 Bad Gateway error is returned during a call. The cause is that HTTP proxy parameters for the intranet environment are not configured, or the proxy username and password are entered incorrectly, preventing connection to external data source APIs.
Missing financing data fields are returned after a call. The cause is that the duplicate_keys parameter is not configured, leading to repeated data pulls that overwrite some fields, or empty field fault tolerance rules are not enabled, causing missing fields to be blocked.
A 400 Bad Request error is returned during a call. The cause is that unit conversion is not performed for the 融资金额 field, causing the unit returned by the data source to not match the interface's expected format, triggering parameter verification failure.

How to Confirm Correct Configuration

Submit a test request in the FastGPT HTTP plugin debug panel, and verify that the returned JSON data fields are complete, with no missing entries or format errors.
Review the plugin's log records to confirm that the scheduled pull task triggers according to the preset cycle, and there are no timeout or connection failure errors.
Manually compare the financing amount returned by the API with the unit converted by the plugin, to verify that the convert_unit_field configuration takes effect.
Call the interface twice, and check that the number of returned events has no duplicate entries, to confirm that the duplicate_keys configuration takes effect.
