Overview

QCC API gives you programmatic access to KYB, KYC, AML and due-diligence data. This documentation covers the concepts you need; the full endpoint reference - parameters, response dictionaries, samples and a test console

Your first call, in four steps

Create an account - register in minutes, or talk to our commercial team about an enterprise plan. Find your available credentials under My account.
Authenticate - include ApiKey, Timespan and Token headers on every call (see Authentication).
Use your available environment - self-service accounts call Production directly; trial and enterprise accounts can validate integrations in Sandbox first.
Make the call - Try it selects the right account credential automatically; real-time products answer in one round-trip, while reports follow Search -> Order -> Retrieve.

Key concepts

Term	Meaning
Credit	The billing unit. One balance works across all QCC services; each product page shows its cost per call.
Free trial call	A per-product allowance for trying self-service APIs, granted at registration, with a validity period.
qccCode / personKeyNo	The unique identifier of an entity / individual, returned by search and used to order data services.
orderNo	Returned when a report order is accepted; used to retrieve the dataset.
Real-time vs. asynchronous	Real-time products return data in the same response; report products are ordered first and retrieved when ready.
Sandbox vs. production	Sandbox is free and returns fixed test data - for integration testing. Production returns live data and is billed.

One response envelope, everywhere

Every API responds with the same wrapper - and returns it inside an HTTP 200 even when the business result is empty or invalid. Always check the status field, not just the HTTP code:

{
  "status": "200",                    ← QCC status code — the one to check
  "msg":    "Valid Request. Query succeeded.",
  "result": { … }                     ← the data (or resultList for searches)
}

All codes and their meanings: Status Codes.
