POST/api/v1/document/analysis/business_document

Submit a business registration certificate or other business document by URL and get back the detected document type, registration number, legal name, entity type and registered address. Accepts image files (JPEG, PNG) — PDFs aren’t supported.

Headers

Header	Required	Description
`Authorization`	Yes	Your app’s secret key, sent as-is — not `Bearer`.
`AppId`	Yes	The App ID from your dashboard.
`Content-Type`	Yes	`application/json`

Body parameters

Parameter	Type	Required	Description
`input_type`	string	Yes	`url` (default) or `base64`.
`input_value`	string	Yes	The image URL (or Base64) of the business document.

Response

A 200 returns the extracted business details under entity — see the panel on the right.

Errors

Code	Meaning
`400`	Bad request — a required field is missing or the image can’t be read.
`401`	Unauthorized — check your key and `AppId` (no `Bearer` prefix).
`402`	Insufficient wallet balance. Fund your wallet.
`424`	Failed dependency — the analysis engine couldn’t process the document.
`429`	Too many requests — back off and retry.
