Assembled from doc.youverify.co/api-reference-sdk/api-reference/quick-check, endpoints kept in the exact order they appear in the GitBook navigation. Some endpoints (address-verification "create a candidate" / "get states" / "retrieve" / "history") are documented twice in the source docs — once for individuals under KYC, once for businesses under KYB — and are the exact same request/response shape. They appear ONCE here (at their first, KYC, position) tagged with both sections so the file stays valid OpenAPI. Account-wide error responses (401, 429, 500 on every endpoint; 402 on paid verification calls; 404 on lookup-by-ID calls) are sourced verbatim from Youverify's own "Youverify OS Error Codes" and "Response Codes" pages (doc.youverify.co/youverify-os-error-codes, /get-started/response-codes) and attached via components.responses, since those pages document them account-wide rather than per endpoint. Any error example that a specific endpoint's own page actually showed is kept exactly as documented there instead of being replaced by these. contact: name: Youverify Support email: support@youverify.co servers: - url: https://api.youverify.co description: Production (live, billed) - url: https://api.sandbox.youverify.co description: Sandbox (test data, not billed) security: - ApiKeyAuth: [] tags: - name: KYC - Global description: Identity data-matching endpoints that work across countries. - name: KYC - South Africa description: South Africa-specific identity, phone and bank verification. - name: KYC - Kenya description: Kenya-specific identity, phone, bank, credit and employment verification. - name: KYC - Ghana description: Ghana-specific identity verification (passport, SSNIT, voter's card). - name: KYC - Nigeria description: >- Nigeria-specific identity, phone, bank and credit verification (BVN, NIN, etc). - name: KYC - Cote D'Ivoire description: Cote D'Ivoire-specific national ID and residence card verification. - name: KYC - General description: >- Identity retrieval, history and facial comparison, not tied to one country. - name: KYC - Address Verification (Individuals) description: >- Physical and digital address verification workflows for individuals.
