Middesk

Ecosystem

Business identity and verification platform. Middesk provides APIs for KYB (know your business), business search, and merchant onboarding. UCP ecosystem participation is early-stage.

Middesk automates business identity verification for financial services and fintech companies. The platform pulls from government databases, business registries, and watchlists to verify business legitimacy during onboarding.

For UCP, Middesk is a candidate for the business identity layer in B2B commerce flows. An agent initiating a high-value procurement transaction could trigger Middesk verification to confirm the counterparty is a legitimate business. Direct UCP tooling does not yet exist.

Why This Matters for UCP

Middesk provides business identity verification that can be integrated into B2B UCP flows, allowing platforms to confirm counterparty legitimacy before AI agents initiate high-value procurement transactions.

Integration Example

// Middesk is used for business identity verification, not direct UCP.
// Integrate Middesk as part of a B2B UCP onboarding flow.

// Verify a business before allowing UCP agent purchases
async function verifyBusinessForUcp(businessName: string, ein: string) {
  const response = await fetch('https://api.middesk.com/v1/businesses', {
    method: 'POST',
    headers: {
      Authorization: `Bearer ${process.env.MIDDESK_API_KEY}`,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({ name: businessName, tin: ein }),
  });
  const business = await response.json();
  // Check business.status === 'approved' before granting UCP agent access
  return business;
}
