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/).

Mobile carrier addresses are not yet detected. test_scenario appears only on an assessment made with a test key (nrk_test_), which the deterministic simulator answers: its impact is the scenario the magic email or phone chose, and none for any other identifier. A live assessment never carries it. shared_api_key is an account reason, never an assessment one: it appears only in the risk of GET /v1/accounts/{account_id} and the account an assessment carries, when a key your account creation gate issued to the account (issued_credential.sha256) was used from many IP addresses or countries within 24 hours (POST /v1/keys/usage). list_match is an account reason too: one of the account's admitted assessments sent an email, or an email of a domain, on the environment's list (GET /v1/workspaces/{workspace_id}/lists/{environment}). It names the entry in list_entry_id; it raises for a block entry and lowers for an allow entry, and it decides the account whatever the score, which it leaves unchanged. reported_account_abuse is an account-only, tenant-local assertion from a known abuse outcome; it is not independently corroborated evidence and is withdrawn by a correction of that report. direction: enum: - raises - lowers - neutral impact: enum: - none - low - medium - high identifier: enum: - email - username - phone - name - ip - context description: >- The submitted identifier or bounded client context a reason concerns; absent when it concerns the whole assessment.

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. ```` This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
