  title: NoResponse API
  version: '1'
  description: >-
    The NoResponse API assesses an account creation, login or purchase and
    answers with the account's one current risk: a 0 to 100 score, a decision
    for the flow (`allow`, `step_up`, `review` or `block`), the reasons behind
    it and the decision for each flow. The assessment's own facts, such as its
    status, confidence and incomplete sources, sit under `detail`.


    Authenticate every request with your API key as `Authorization: Bearer
    nrk_...`. Call the API only from your backend.


    Guides, SDKs and webhook verification are at
    [docs.noresponse.org](https://docs.noresponse.org/). Every error is an RFC
    9457 problem document; see
    [Errors](https://docs.noresponse.org/reference/errors).

              email of the domain. A block entry decides block for every flow
              and an allow entry decides allow; when both match, block wins. The
              account's risk carries the list_match reason with the entry's id,
              and its score stays the one the assessment's facts give. A held

      description: >-
        Your API key, sent as `Authorization: Bearer <key>`. A key is
        `nrk_live_` or `nrk_test_`, a 26-character key id, `_` and a
        43-character secret. Account, audit and usage data stay within the key's
        environment. Dedicated team scopes apply across the workspace.


        `assess` creates and reads assessments, records outcomes and reports key
        usage. `investigate` reads accounts, assessment history and request
        diagnostics without export or enforcement access. The legacy `history`
        scope also permits account exports, submitted identifiers and
        enforcement reports. `delete` permits account and assessment deletion.


        `evidence` or `detailed` adds detailed merged evidence and submitted
        identifiers where the operation permits them. Neither grants access to
        the underlying resource alone. `exports` permits exports with the
        underlying account or audit scope. `audit` reads audit events and
        `usage` reads usage. `audit_manage` manages audit streams and retention,
        and includes audit-read and export authority.


        `webhooks` manages webhook endpoints. `integrations` manages hosted
        auth-provider integrations. `management` manages keys, settings, lists,
        reviews and policy evaluations in the key's environment. New keys cannot
        exceed the issuer's effective permissions.


        `settings` reads configuration, previews policy and list changes, runs
        evaluations and changes retention. Publishing decision policy or
        changing lists requires `settings` and `policy_publish` together, or the
        legacy `management` scope.


        `groups` creates and reads groups, adds people, starts and cancels
        screenings and records decisions on people, in the key's environment.


        `members` reads the workspace directory. `members_manage` also
        administers non-owner members and invitations. These scopes require a
        live key issued by a current owner with access to both environments.
        They grant access across the workspace. `management` does not grant team
        access. API keys cannot change owners or accept invitations.


        A missing, unknown, revoked or expired key answers 401. A valid key
        without a required scope answers 403.
