# Subscribe to Entity News

PUT https://api.aventure.vc/v1/news/subscriptions
Content-Type: application/json

Creates or refreshes a webhook subscription to news newly linked to one entity. A new endpoint must echo a signed verification challenge before the subscription exists.

Reference: https://docs.aventure.vc/api-reference/news/subscribe-news-subscription

## Authentication

- `Authorization` header (bearer token, required) — Your aVenture API key (https://aventure.vc/settings/api-keys) or OAuth access token

## Request

### Body (application/json)

This endpoint expects a NewsSubscription.

- `arguments` (NewsSubscriptionArguments, required) — Arguments of the entity.news.published event.
- `delivery` (NewsSubscriptionDelivery, required) — Webhook delivery target and secret.
- `name` (enum, required) — Subscribable event name
  - Allowed values: `entity.news.published`
- `cursor` (string, optional, nullable) — Opaque watermark from an earlier grant or event to resume after; null starts a new subscription from now and keeps an existing subscription's position.
- `ttlMs` (long, optional, nullable) — Requested subscription lifetime in milliseconds; the server caps it.

## Response

### 200

OK

- `cursor` (string, required) — Opaque watermark the subscription delivers after.
- `id` (string, required) — Stable subscription id; sent as X-MCP-Subscription-Id.
- `refreshBefore` (datetime, required) — The subscription expires unless refreshed before this instant.
- `truncated` (boolean, required) — Whether events between the requested cursor and now were lost.

## Errors

### NewsSubscriptionDelivery

Webhook delivery target and secret.

- `mode` (enum, required) — Event delivery mode
  - Allowed values: `webhook`
- `secret` (string, required) — Standard Webhooks signing secret: whsec_ followed by base64 of 24 to 64 bytes. It is never returned. The CLI reads it only from --from-file, never a flag.
- `url` (string, required) — Public https endpoint that receives signed event POSTs.

### CurrentSlugOwner

- `deletedAt` (datetime, optional, nullable)
- `nameBrand` (string, optional, nullable)

### DomainConflictDetails

Polymorphic envelope for RFC 9457 ProblemDetail.details on HTTP 409 responses. The concrete variant depends on the conflict kind: URL ownership collisions return UrlDuplicateConflict; ambiguous strict URL lookups return StrictUrlLookupConflict; create-time duplicate review gates return DuplicateCreateReview; classification writes that touch an inactive tag bucket return ClassificationInactiveTagDetails; news publication+URL uniqueness violations return NewsSourceUrlConflict. Inspect ProblemDetail.code/type and the field set present on details to identify the variant.

### RedirectSlugPath

Redirect slug path

- `oldUrl` (string, required)
- `newUrl` (string, optional, nullable)
- `targetCurrentSlug` (string, optional, nullable)
- `targetId` (string, optional, nullable)
- `targetResourceType` (enum, optional, nullable) — Resource type whose slug is being changed
  - Allowed values: `entity`, `person`, `news`, `blog`, `content`

### ProblemResolution

Machine-readable next action for an aVenture ProblemDetail. For reviewCandidates, inspect ProblemDetail.details candidates and decide update, create-with-override, or block from those returned records.

- `action` (enum, required) — Next action category for the client or agent.
  - Allowed values: `setField`, `setParameter`, `removeParameter`, `useEndpoint`, `reviewCandidates`, `authenticate`
- `acceptedValue` (list of string, optional, nullable) — Accepted values for the field or parameter, when enumerable.
- `endpoint` (string, optional, nullable) — Endpoint to call for the next action, when applicable.
- `fieldPath` (string, optional, nullable) — Request-body field path that needs attention, when applicable.
- `parameter` (string, optional, nullable) — Query parameter that needs attention, when applicable.
- `retryable` (boolean, optional, nullable) — Whether the same logical request can be retried after the next action.

### UrlDuplicateConflict

Typed extension on ProblemDetail.details for HTTP 409 when a create/update attempts to set a URL with urlType=website (or another exclusive urlType) that is already a current URL on a different entity or person. The existingJoin list names every current owner of the normalized URL; resolve by demoting the existing owner (isCurrent=false, isPrimary=false) before promoting the new owner.

- `existingJoin` (list of UrlDuplicateJoin, required) — Every current owner that already holds the normalized URL with this urlType. Non-empty when this conflict is emitted.
- `fragmentIgnored` (boolean, required) — True when URL fragment differences were ignored during duplicate matching (i.e., the conflict ignores everything after '#').
- `guidance` (string, required) — Human-readable guidance on how to resolve the conflict. Defaults to the standard inspect-then-demote/promote sequence.
- `requestedOwner` (EntityPersonOwner, required) — Owner the caller attempted to attach the URL to.
- `url` (string, required) — Raw URL as submitted by the caller (pre-normalization).
- `urlType` (string, required) — URL type submitted by the caller (e.g., 'website', 'twitter'). The conflict applies only within this urlType.
- `normalizedUrl` (string, optional, nullable) — Normalized URL match key used for duplicate detection. Null when normalization could not produce a stable key (e.g., malformed input).

### StrictUrlLookupConflict

Typed extension on ProblemDetail.details for HTTP 409 when a strict URL lookup (GET /v1/entities/lookup-exact?url=...) resolves to more than one current owner. The candidate lists return every current owner that matches the normalized URL key; the caller must add disambiguating signals (urlType, typeRecord, slug) to resolve to a single owner.

- `candidateEntityId` (list of string, required) — Every entity id that currently owns the normalized URL. May be empty when the conflict is between persons; combined with candidatePersonId always > 1.
- `candidatePersonId` (list of string, required) — Every person id that currently owns the normalized URL. May be empty when the conflict is between entities; combined with candidateEntityId always > 1.
- `hint` (string, required) — Human-readable hint describing which disambiguating query parameters to add.
- `url` (string, required) — Raw URL the caller queried.
- `normalizedUrl` (string, optional, nullable) — Normalized URL match key the lookup resolved against. Null when normalization could not produce a stable key.
- `urlType` (string, optional, nullable) — URL type the caller specified, or null if the lookup did not constrain by urlType.

### DuplicateCreateReview

Candidate-review conflict details returned in ProblemDetail.details for create gates and deterministic lookup ambiguity. The returned candidates are the decision surface: update the matching candidate, create with duplicate override only when every candidate is distinct from the source-backed target, or block when identity is unresolved. score and threshold rank review priority; they are not proof that the requested record is absent.

- `threshold` (integer, required) — Review threshold used by duplicate scoring. Scores below this value can still be useful candidate context; this value does not prove absence or authorize create.
- `candidate` (list of SearchDuplicateCandidateScore, optional, nullable) — Entity/person candidates returned by lookup or create duplicate review. If a candidate is the requested record, read/update that candidate by id. Create with duplicate override only after every candidate is reviewed as distinct.
- `newsCandidate` (list of NewsCandidateScore, optional, nullable) — News candidates returned by lookup or create duplicate review. If a candidate is the requested article, read/update that article by id. Otherwise block until source evidence proves a distinct article.
- `overridePath` (string, optional, nullable) — Create endpoint to retry only after reviewing the returned candidates and supplying overrideGate=duplicate and overrideReason as query parameters. Null for detail lookup ambiguity, where the next action is review/update/block.

### ClassificationInactiveTagDetails

ProblemDetail.details for HTTP 409 when a classification value exists but is inactive.

- `availableOverrides` (list of enum, required) — Allowed inactiveTagOverride values for this conflict
  - Allowed values: `REACTIVATE`, `ATTACH_INACTIVE`
- `slug` (string, required) — Existing dormant value slug or lookup key
- `tagId` (integer, required) — Existing tag id in res_type_ref

### NewsSourceUrlConflict

Typed extension on ProblemDetail.details for HTTP 409 when a news mutation's publication + newsUrlOriginal pair already belongs to another article. The returned fields identify the existing article so the caller can read/update it instead of creating a duplicate.

- `conflictingArticleId` (integer, required) — Existing article id (NewsId.value) that already owns this publication + URL pair.
- `conflictingArticleSlug` (string, required) — Existing article slug, or empty string when the existing article has no slug. Use with GET /v1/news/lookup?slug= to fetch the conflicting article.
- `conflictingArticleTitle` (string, required) — Existing article title for human-readable diagnostics.

### UrlDuplicateJoin

URL ownership join row identifying which entity or person currently owns a normalized URL.

- `owner` (EntityPersonOwner, required) — Owner of the URL: either entityId or personId is populated depending on the owner kind. Use the populated id to read or update the owner's URL.
- `urlId` (integer, required) — Internal URL row id (res_weburl.id) — opaque to API clients.

### EntityPersonOwner

Exactly one of entityId or personId is set; ids only, no name fields. Resolve display names with GET /v1/entities/detail or GET /v1/people/\{personId}.

- `entityId` (string, optional, nullable) — Owning entity id; set only when personId is absent.
- `personId` (string, optional, nullable) — Owning person id; set only when entityId is absent.

### SearchDuplicateCandidateScore

Duplicate candidate scoring result. Use id/name/slug/typeRecord/reason to decide whether the candidate is the requested record. score ranks review priority; it does not prove absence.

- `id` (string, required) — Candidate id to read or update when this candidate is the requested record.
- `reason` (list of string, required) — Match reasons such as name-exact, slug-exact, url-match, url-current, url-type, or precomputed-similarity. url-match proves the supplied URL/domain matched; url-current additionally proves the candidate still holds that address today, so a candidate with url-match but no url-current matched only through a URL it no longer uses, such as an acquisition redirect. url-type only means the candidate has the same URL category and is review context, not URL identity evidence.
- `score` (integer, required) — Ranking score for duplicate review. It is not an absence proof; a low score can still be the intended record when reason/name/slug/typeRecord match.
- `externalId` (string, optional, nullable) — Matched external identifier when duplicate scoring used one.
- `name` (string, optional, nullable) — Candidate display name from the existing record.
- `operatingStatus` (string, optional, nullable) — Current operating status for entity candidates.
- `publicPath` (string, optional, nullable) — Public API/UI path for the candidate when available.
- `slug` (string, optional, nullable) — Candidate slug from the existing record.
- `typeRecord` (enum, optional, nullable) — Candidate entity type from the existing record.
  - Allowed values: `Company`, `Investment Firm`, `Fund`, `Nonprofit`, `Government`, `Organization`, `Business Line`, `Product`, `Service`

### NewsCandidateScore

Duplicate candidate scoring result for news articles. Use id/slug/externalId/reason to decide whether the candidate is the requested article. score ranks review priority; it does not prove absence.

- `id` (integer, required) — News article id to read or update when this candidate is the requested article.
- `reason` (list of string, required) — Match reasons for reviewing the candidate. Exact reasons are decision signals regardless of whether score crosses the review threshold.
- `score` (integer, required) — Ranking score for duplicate review. It is not an absence proof; a low score can still be the intended article when reason/slug/externalId match.
- `externalId` (string, optional, nullable) — Matched external article identifier when duplicate scoring used one.
- `slug` (string, optional, nullable) — Candidate article slug from the existing record.
