Securitize Connect API (Securitize iD)

name: Securitize Connect API (Securitize iD)
description: OAuth-based identity API that lets partners add "Log in with Securitize iD" to their own
  application and, with investor consent, retrieve verified KYC/KYB/AML identity data — investor information,
  verification details, investor documents, legal signers, and registered wallets. Scopes are limited
  to info, details, and verification. Documented endpoint surface only; Securitize publishes no machine-readable
  specification for this API and the Swagger reference its docs link to now returns 404.

    on both the sandbox and production hosts returned 404 on 2026-08-05. No OpenAPI was authored on the
    provider's behalf.
