Duplicates

NeuralRepo automatically detects potential duplicate ideas using semantic similarity. The duplicates API lets you review, dismiss, or merge detected pairs.

List Duplicates

GET /api/v1/ideas/duplicates

Returns pairs of ideas that NeuralRepo has flagged as potential duplicates.

curl

curl https://neuralrepo.com/api/v1/ideas/duplicates \
  -H "X-API-Key: nrp_YOUR_KEY"

JavaScript

const res = await fetch(
  "https://neuralrepo.com/api/v1/ideas/duplicates",
  { headers: { "X-API-Key": "nrp_YOUR_KEY" } }
);
const duplicates = await res.json();

Response 200 OK

{
  "duplicates": [
    {
      "id": 1,
      "idea_id": 58,
      "duplicate_of_id": 42,
      "similarity_score": 0.94,
      "status": "pending",
      "created_at": "2026-03-22T14:00:00Z"
    }
  ]
}

The similarity_score field is a score between 0 and 1 indicating how closely the two ideas match.

Dismiss Duplicate

POST /api/v1/ideas/duplicates/:id/dismiss

Marks a duplicate pair as not-a-duplicate. The pair will no longer appear in the duplicates list.

curl

curl -X POST https://neuralrepo.com/api/v1/ideas/duplicates/1/dismiss \
  -H "X-API-Key: nrp_YOUR_KEY"

JavaScript

const res = await fetch(
  "https://neuralrepo.com/api/v1/ideas/duplicates/1/dismiss",
  {
    method: "POST",
    headers: { "X-API-Key": "nrp_YOUR_KEY" },
  }
);

Response 200 OK

{
  "success": true
}

Merge Duplicate

POST /api/v1/ideas/duplicates/:id/merge

Merges the duplicate pair. One idea absorbs the other — the absorbed idea’s body, tags, links, and relations are folded into the surviving idea. The absorbed idea is archived.

curl -X POST https://neuralrepo.com/api/v1/ideas/duplicates/1/merge \
  -H "X-API-Key: nrp_YOUR_KEY"

Response 200 OK

{
  "success": true
}

Workflow

A typical duplicate review workflow:

1. List duplicates with GET /ideas/duplicates.
2. For each pair, decide whether to dismiss (false positive) or merge (true duplicate).
3. Dismissed pairs are hidden from future listings.
4. Merged pairs consolidate content and archive the duplicate.

Status Codes

Status	Meaning
200 OK	Duplicates listed, dismissed, or merged
401 Unauthorized	Missing or invalid auth
404 Not Found	Duplicate pair not found
409 Conflict	Merge conflict (e.g., one idea already archived)
