# Review person duplicate gates

POST https://api.aventure.vc/v1/people/duplicate-check
Content-Type: application/json

USE FOR: Deterministic duplicate-check identity gates before create or update. An empty page is not proof no person exists; when create returns 409, use that ProblemDetail.details.candidate as the authoritative create decision surface. After a successful person id/slug/url bootstrap, rerun exact-name review with excludeId set to that person id before enrichment completion or merge decisions. NOT FOR: General people browsing and list/search discovery flows.

Reference: https://docs.aventure.vc/api-reference/a-venture-api/people-v-1/duplicate-check-people-post

## Authentication

- `X-Client-Secret` header (required) — Client secret for read-only service-to-service access (no writes)

## Request

### Query parameters

- `page` (integer, optional) — Zero-based page index (0..N)
- `size` (integer, optional) — The size of the page to be returned; duplicate-check default 10, maximum 100.
- `sort` (list of string, optional) — Sorting is not supported
- `includePrivate` (boolean, optional) — Privileged read scope for admin callers. Bypasses the public visibility filter so hidden, unverified, and not-yet-published records are returned instead of being silently dropped. Defaults to private for admin API key or ROLE_ADMIN callers; client-secret/client-read callers stay public.

### Body (application/json)

- `excludeId` (string, optional, nullable) — Current person id to omit from post-bootstrap duplicate audits while same-name candidates are reviewed.
- `location` (string, optional, nullable) — Location
- `nameAny` (string, optional, nullable) — Loose name match
- `nameFull` (string, optional, nullable) — Full name
- `qwen4bFp16Embedding` (list of float, optional, nullable) — Embedding vector pinned to qwen-4b-fp16 (Qwen3-Embedding-4B-f16.gguf) from https://huggingface.co/Qwen/Qwen3-Embedding-4B-GGUF?show_file_info=Qwen3-Embedding-4B-f16.gguf; only this fp16 model is accepted and exactly 2560 floats are required
- `slug` (string, optional, nullable) — URL-safe identifier
- `url` (string, optional, nullable) — Profile URL
- `urlCandidate` (list of object, optional) — Additional URL candidates to match
  - `url` (string, optional, nullable) — Duplicate URL value
  - `urlType` (enum, optional, nullable) — Canonical URL platform type such as website, linkedin, twitter, or github. Lifecycle facts belong on link flags such as isCurrent and isPrimary.
    - Allowed values: `website`, `linkedin`, `twitter`, `github`, `facebook`, `instagram`, `tiktok`, `youtube`, `subreddit`, `forum`, `documentation`, `support`, `statuspage`, `changelog`, `roadmap`, `discord`, `crunchbase`, `wellfound`, `angellist`, `glassdoor`, `theorg`, `ycombinator`, `wikipedia`, `pitchbook`, `morningstar`, `bloomberg`, `nyse`, `nasdaq`, `g2`, `producthunt`, `trustpilot`, `alternativeto`, `gartnerpeerinsights`, `getapp`, `sourceforge`, `appstore`, `googleplay`, `capterra`, `trustradius`, `hubspotmarketplace`, `slackappdirectory`, `awsmarketplace`, `salesforceappexchange`, `chromewebstore`, `vscodemarketplace`, `npm`, `pypi`, `maven`, `dockerhub`, `homebrew`, `crates`

- `urlMatchMode` (enum, optional, nullable) — URL match mode
  - Allowed values: `hostPath`, `domain`
- `urlStrictness` (enum, optional, nullable) — Optional URL match strictness. Omit for strict matching. Send loose or any only when the caller intentionally widens URL matching.
  - Allowed values: `strict`, `loose`, `any`
- `urlType` (enum, optional, nullable) — URL type
  - Allowed values: `website`, `linkedin`, `twitter`, `github`, `facebook`, `instagram`, `tiktok`, `youtube`, `subreddit`, `forum`, `documentation`, `support`, `statuspage`, `changelog`, `roadmap`, `discord`, `crunchbase`, `wellfound`, `angellist`, `glassdoor`, `theorg`, `ycombinator`, `wikipedia`, `pitchbook`, `morningstar`, `bloomberg`, `nyse`, `nasdaq`, `g2`, `producthunt`, `trustpilot`, `alternativeto`, `gartnerpeerinsights`, `getapp`, `sourceforge`, `appstore`, `googleplay`, `capterra`, `trustradius`, `hubspotmarketplace`, `slackappdirectory`, `awsmarketplace`, `salesforceappexchange`, `chromewebstore`, `vscodemarketplace`, `npm`, `pypi`, `maven`, `dockerhub`, `homebrew`, `crates`
