source: https://developer.uzumbank.uz/en/ (per-product Authentication sections) + openapi/ securitySchemes
docs: https://developer.uzumbank.uz/en/
note: >-
  Derived from the four specs that declare a securitySchemes block, then upgraded from the
  Authentication section published in each product's own OpenAPI info.description on
  developer.uzumbank.uz. Five of the nine contracts (Checkout, Fast Pay, Dynamic QR,
  Fiscalization, RateKeeper) document their credential model in prose but never declare a
  securityScheme in the spec, so an agent reading only the machine-readable contract cannot
  see how to authenticate. That gap is recorded below per API.
summary:
  types:
  - apiKey
  - http
  api_key_in:
  - header
  oauth2: false
  openid_connect: false
  mutual_tls: false
  self_service: false
  credential_issuance: >-
    Every Uzum Bank API credential is issued by an Uzum account manager after a commercial
    agreement. There is no self-service key generation on any surface.
schemes:
- name: basicAuth
  type: http
  scheme: basic
  sources:
  - openapi/uzum-crossborder-openapi.yaml
  - openapi/uzum-merchant-openapi.yaml
  apis:
  - Uzum CrossBorder Transfer
  - Uzum Merchant API
  - Uzum BaaS Payment Hub
  note: >-
    Login and password issued per partner, base64-encoded into `Authorization: Basic`.
    Payment Hub additionally requires Content-Type: application/json and Accept-Language
    (EN/RU/UZ) and states TLS 1.2 for transport.
  docs: https://developer.uzumbank.uz/en/paymenthub/auth/
- name: BearerAuth
  type: http
  scheme: bearer
  bearerFormat: JWT
  sources:
  - openapi/uzum-nasiya-openapi.yaml
  apis:
  - Uzum Nasiya Partner API
  note: '`Authorization: Bearer <token>` on every request.'
- name: XApiKeyAuth
  type: apiKey
  in: header
  parameter: X-Api-Key
  description: Partner API key in UUID format. Issued upon onboarding. Required for all methods
  sources:
  - openapi/uzum-remitcore-openapi.yaml
  apis:
  - Remit Core
  note: >-
    Production access additionally requires an IPSec tunnel and IP allow-listing; the
    internet-reachable host is the test environment only.
undeclared_in_spec:
- api: Uzum Checkout
  spec: openapi/uzum-checkout-openapi.yaml
  documented_scheme: apiKey (two headers)
  headers:
  - name: X-Terminal-Id
    description: Transaction-processing terminal identifier assigned to each partner.
  - name: X-API-Key
    description: Unique API key assigned to each partner.
  - name: Content-Language
    description: 'Payment-form locale. Enum: ru-RU, uz-UZ, en-EN.'
  source: https://developer.uzumbank.uz/en/checkout
  gap: securitySchemes absent from the OpenAPI; documented only in info.description.
- api: Uzum Fast Pay
  spec: openapi/uzum-fastpay-openapi.yaml
  documented_scheme: signed header
  headers:
  - name: Authorization
    description: >-
      Composite signed value matching regex ^\d*:(\d{40}):\d*$ — merchant_id, a 40-character
      hash, and a millisecond timestamp. Requests are rejected (error 403) when more than 50
      seconds elapse between signing and processing, so the signature is time-bound.
  source: https://developer.uzumbank.uz/en/fastpay
  gap: securitySchemes absent from the OpenAPI.
- api: Uzum Dynamic QR
  spec: openapi/uzum-dynamicqr-openapi.yaml
  documented_scheme: signed header (same construction as Fast Pay)
  source: https://developer.uzumbank.uz/en/dynamicqr
  gap: securitySchemes absent from the OpenAPI.
- api: Uzum Fiscalization
  spec: openapi/uzum-fiscalization-openapi.yaml
  documented_scheme: apiKey
  headers:
  - name: API Key
    description: >-
      Unique identifier generated and provided by the Uzum development team per partner.
      Separate keys are issued for the test and production hosts.
  source: https://developer.uzumbank.uz/en/fiscalization
  gap: securitySchemes absent from the OpenAPI.
- api: Uzum RateKeeper
  spec: openapi/uzum-ratekeeper-openapi.yaml
  documented_scheme: unknown
  gap: >-
    The spec declares no securitySchemes and carries no info.description; the portal page
    publishes no authentication section for this product.
- api: Uzum Market Seller API
  documented_scheme: bearer token issued in the seller cabinet
  source: https://api-seller.uzum.uz/swagger-ui/index.html
  gap: >-
    Anonymous requests return 403 "RBAC: access denied" and the Swagger UI 302s to a
    Keycloak realm (auth.infra.cluster.daymarket.uz, realm `umarket`, client
    `platform-client-prod`). No public contract or auth reference is served.
oauth:
  present: false
  note: >-
    No OAuth 2.0 or OpenID Connect surface is exposed to partners on any documented Uzum
    Bank API. The only OIDC deployment observed is the internal Keycloak realm fronting the
    Uzum Market seller cabinet, which is not a partner authorization surface. scopes/ is
    therefore not applicable and no OAuthScopes artifact is emitted.
