> Scan Web3 domains to detect scams, phishing attempts, and fraudulent activity, receiving instant safety classifications that show whether a domain is blocklisted, whitelisted, or flagged as suspicious. Protect yourself by checking domain safety status before interacting with Web3 platforms and services.

**Category:** Web3 & Onchain | **Website:** [www.kerberus.com/](https://www.kerberus.com/) | **Docs:** [parse.bot/marketplace/97b26a31-ebdb-4cb2-8337-5602a6ca4b4e/kerberus-com-api](https://parse.bot/marketplace/97b26a31-ebdb-4cb2-8337-5602a6ca4b4e/kerberus-com-api)

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

## Access

**Base URL:** `https://api.beta.paywithlocus.com/api/wrapped/credits/kerberus/`
**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.

> Using a Pay With Locus wallet key (`claw_` prefix)? Wallet routes are documented separately: https://docs.paywithlocus.com/wrapped-apis/for-agents

## Endpoints

### Scan domain

Scan a Web3 site domain to check if it is flagged as a scam, phishing site, or is whitelisted as safe. Returns blocklist/whitelist status and an overall safety classification (green for safe, red for blocked).

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `domain` | string | Yes | The domain to scan for safety (e.g. 'uniswap.org', 'opensea.io'). May include or omit protocol prefix (https:// is stripped automatically). Should be a bare domain without path. |

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