**Category:** Developer Tools | **Website:** [plagiarismdetector.net/](https://plagiarismdetector.net/) | **Docs:** [parse.bot/marketplace/266cb40d-eaf9-46f5-b658-bed7c13739fb/plagiarismdetector-net-api](https://parse.bot/marketplace/266cb40d-eaf9-46f5-b658-bed7c13739fb/plagiarismdetector-net-api)

Pay-per-use API proxy for Locus Pro. Each call burns credits from your workspace balance.

## Access

**Base URL:** `https://api.paywithlocus.com/api/wrapped/credits/plagiarismdetector/`
**Auth:** `Authorization: Bearer <LOCUS_CREDITS_SECRET_KEY>` (an `lcr_` secret key or a scoped `lcac_` agent credential)
**Required header:** `Idempotency-Key: <fresh UUID per call>`. A retry with the same key replays the stored result without a new charge.
**Response:** the provider response after any endpoint-specific normalization. `X-Locus-Credits-Charged` carries the charge and `X-Locus-Credits-Balance` the remaining balance. Insufficient credits return `402` before the provider is called.
**Pricing:** estimated costs below are USD. Locus debits the credit equivalent at your workspace rate.

## Endpoints

### Check plagiarism

Checks text for plagiarism by splitting it into sentences and comparing each against web sources. Returns overall unique/plagiarized percentages and per-sentence analysis with matching source URLs. Each call solves a reCAPTCHA and makes multiple sequential requests (form submission, sentence splitting, plagiarism check), so latency is typically 10-20 seconds. Limited to 1000 words per check on the free tier.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `exclude_url` | string | No | A URL to exclude from plagiarism matching results. Useful when checking content that is already published at a known URL. |
| `text` | string | Yes | The text content to check for plagiarism. Must not be empty. Limited to 1000 words on the free tier. |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/plagiarismdetector/check-plagiarism \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"exclude_url":"<string>","text":"<string>"}'
```

### Detect ai content

Detects whether text was written by AI or a human. Returns overall AI/human content percentages and sentence-level classification. Each call solves a reCAPTCHA v2 and makes multiple sequential requests, so latency is typically 10-20 seconds. Limited to 2000 words per check on the free tier.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `text` | string | Yes | The text content to analyze for AI-generated content. Must not be empty. Limited to 2000 words on the free tier. |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/plagiarismdetector/detect-ai-content \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"text":"<string>"}'
```
