Features:

Business Registry Verification:

For these 3 products, the key request parameters are the same: companyName, region, registrationNumber, mode, maxLayer(maxLayer is only for Business Registry Verification -Pro). And the results of these 3 products can be gotten from the Get Business Verification Result API.

Product	Description
Business Registry Verification - Standard	Verify whether the company exists
Business Registry Verification - Advance	Verify whether the company exists Verify company registration information
Business Registry Verification -Pro	Verify whether the company exists Verify company registration information Verify officer and shareholder information

Data Source Mode：

Mode	Description
LIVE	Retrieves the latest records directly from primary official sources. Recommended for production use.
CACHE	Leverages global databases for maximized search depth and global reach.
HYBRID	Hybrid mode intelligently routes requests to the optimal data source by evaluating multiple factors, such as coverage, price, latency, number type and so on. The specific mode used for a given call—whether direct connection or cache—is indicated in the output. Hybrid mode is supported only in Business Registry Verification -Pro products.

Multi-Layer:

For Business Registry Verification -Pro, if the maxLayer parameter is designated, this product will execute the multi-layer penetration function based on the maximum number of layers.

Deepest ownership layer to return, counting the subject company as layer 1.
Optional — omit it to keep the single-layer behaviour.

2 (default) — the subject company and its own register only.
3-10 — ownership traversal: every corporate shareholder on a register is looked up in turn, layer by layer, until maxLayer is reached. Each returned officer / shareholder carries layer and parentNode.

If a shareholder's shareholding ratio is less than 25% (the default value), or if a special corporate entity is involved, the look-through process stops.

Beneficial Owner Verification:

For this products, the key request parameters are : companyName, region, registrationNumber. And the boInfos results can be gotten from the Get Business Verification Result API.
