Sources

Every factual claim on CompareCEX about an exchange — a fee, a supported country, a license, a security incident — is stored in our Knowledge Graph together with a source URL, a source type, and the date it was last checked. This page explains what those source types mean and how we keep them current.

Source types we use

• Official — the exchange's own website, fee schedule, terms of service, or status page. This is our preferred source for fees, KYC requirements, and country restrictions.
• API — public data pulled directly from an exchange's API (for example, listed trading pairs).
• Third party — regulator registers, licensing authority databases, or established industry publications, used mainly for regulation and security-incident history.
• Manual — data entered or checked by hand when no official or API source is available, always logged with a checked date and a lower confidence score.

How often we check

Fields that change often, like fees, are scheduled for more frequent re-checks than fields that rarely change, like founding year. Every exchange page shows a "last verified" date so you can see exactly how current the information is, rather than assuming it is always fresh.

What we do when a source disagrees with itself

If an official source and a third-party source disagree, we prefer the official source and note the discrepancy internally. We do not average conflicting numbers or guess which one is right.

What we do not do

We do not publish a number because a competitor site has it, and we do not extrapolate or estimate figures and present them as fact. If a data point is not verifiable, it is labeled "unverified" or left out of the page entirely.
