JSON request and response
Verify the business, its officers and its ownership before you onboard.
Manual KYB is a research task: find the entity in a national registry, confirm it is active, identify officers and beneficial ownership, then file the evidence. API4ALL collapses that into two calls — a search that returns a company code, and an order that returns a standardised KYB report drawn from Infocredit’s database.
Because the report format is the same across jurisdictions, your compliance team reviews one consistent document instead of a dozen registry extracts in different languages and layouts. The report is a downloadable file, so it drops straight into the customer file as onboarding evidence.
The integration flow, step by step.
- 01
Authenticate
Create a project-scoped OAuth2 token and refresh it through the token endpoints. Every call carries a bearer token.
- 02
Resolve the entity
Search by registered name or registration number, scoped to country code, and take the returned company code.
- 03
Order the KYB report
Check availability, then create an order for the KYB report type with your client reference number.
- 04
Attach the evidence
Poll order status, download the finished report by order ID and store it against the customer record.
The calls behind this workflow.
Search by name
Match the prospective customer across supported jurisdictions using their registered or trading name.
Search by registration number
Resolve the entity directly from a local company registration or tax identifier for an exact match.
Report availability
Confirm a KYB report exists for the company code before committing to an order.
Create / retrieve order
Place the KYB order with a client reference, poll its status, then download the report as a binary file.

Questions about this use case.
What is KYB verification and why does it matter?
Know Your Business (KYB) verification is the process of confirming a corporate entity's identity, legal status, ownership structure and operational credibility before entering a relationship. It is required for AML/CFT compliance, merchant onboarding, supplier due diligence and high-value B2B transactions.
What does a KYB API do?
A KYB API lets you programmatically search a company by name or registration number, check report availability and order a standardised KYB report — all through REST endpoints. It replaces manual registry research with automated business verification inside your own platform.
What data is included in the API4ALL KYB report?
Each KYB report covers business identity, registration status, incorporation date, registered address, officers and directors, shareholding and ownership structure, and other verification-relevant company information sourced from Infocredit's database.
How does KYB differ from KYC?
KYC verifies individual identity. KYB verifies corporate identity, beneficial ownership and business legitimacy. Many compliance programmes run both: KYC on the person authorised to act, and KYB on the entity itself.
How do I get a KYB report through the API4ALL API?
Authenticate with OAuth2, resolve the entity through the search endpoints by registered name or registration number, then create an order for the KYB report type using the returned company code and your client reference number.
Can I check if a KYB report is available before ordering?
Yes. The report availability endpoint returns which report types are available for a given company code, so you can branch your workflow and avoid paying for reports that cannot be produced.
Which countries are covered by the KYB API?
Company data coverage spans 135+ countries. Availability of a standardised KYB report varies by jurisdiction and can be confirmed per entity through the availability endpoint before ordering.
Is the KYB report format consistent across jurisdictions?
Yes. API4ALL returns a standardised KYB report format, so your compliance team reviews one consistent document instead of registry extracts in different languages and layouts. The report is downloadable for storage against the customer record.
Can KYB verification be integrated into an onboarding decision engine?
Absolutely. KYB ordering and retrieval are plain REST calls with OAuth2 bearer tokens, so they can be wired into onboarding portals, CRM, KYC platforms, payment merchant approval flows and automated decision engines.
Does the KYB API support beneficial ownership and UBO checks?
The KYB report includes officer and ownership data, which supports UBO identification and downstream screening. For deeper ownership trees, combine KYB with the corporate structure and related-party reports also available through API4ALL.
What authentication does the API4ALL KYB API use?
API4ALL uses OAuth2 bearer tokens. You create a project-scoped token, refresh it through the token endpoints, and send it on every request. Tokens are scoped to your project and can be revoked at any time.
How long does it take to receive a KYB report?
Most KYB reports are produced and available for download within minutes. You can poll order status via the API or design your flow to wait for a webhook-style status update, depending on your integration pattern.
