Browse data sources

Every source here is something a user proves by signing in to their own account.

A data source is one thing Vouch can verify from one platform — an Instagram audience breakdown, a TikTok follower count, a Revolut account balance, an Amazon purchase. Each has an ID that you pass to getDataSourceUrl, a set of inputs it needs from you, and a fixed set of outputs it returns.

Pick the fact your decision turns on — eligibility, identity, income, audience, a past purchase — and there is usually a source that proves it.

Choosing a source

Pick a source by the fact you need proven, not by the platform. Several sources often read the same platform for different facts, and several platforms often prove the same fact — which matters, because your user only needs an account with one of them.

• Match the fact to your decision. If you are pricing a creator partnership on audience quality, you want a source that returns demographics and reach, not one that only proves the handle is theirs. If you are qualifying a switching bonus, you want the transaction or balance source, not account ownership.
• Cover your users' actual platforms. Where a check can be satisfied several ways, offer several sources and let the user pick the one they hold. The Vouch widget does this for you.
• Check the inputs. Some sources need a parameter from you, such as a handle or a post URL. See Passing inputs.
• Check the outputs. Open a source in the catalog to see the exact JSON keys it returns before you write your webhook handler.
