Overview

DOSafe is the safety and threat intelligence engine for the DOS ecosystem. It aggregates data from 19+ sources with over 3.93 million threat intelligence entries to provide real-time risk assessments for entities such as domains, URLs, wallets, phone numbers, and more.

Key Capabilities

• Entity check -- Assess the risk of a single entity against the threat intelligence database, on-chain attestations, and DOS.Me identity data.

• Bulk check -- Evaluate up to 50 entities in a single request.

• URL check -- Analyze a URL for phishing, scam, and malware indicators.

• AI text detection -- Determine whether a piece of text was generated by AI.

• AI image detection -- Determine whether an image was generated or manipulated by AI.

• AI video detection -- Analyze video for AI-generated content using a 7-layer pipeline (frame analysis, temporal consistency, audio-visual sync, LLM visual reasoning).

• AI audio detection -- Detect AI-generated speech and voice clones using BEATs + mHuBERT ensemble (AUROC 0.88).

• Face verification -- Liveness detection and face matching for identity verification.

API Endpoints

All DOSafe endpoints use the base URL https://api.dos.ai/v1/dosafe.

Method	Endpoint	Description
POST	/v1/dosafe/check	Single entity safety check
POST	/v1/dosafe/check/bulk	Bulk entity check (max 50)
POST	/v1/dosafe/url-check	URL/domain safety check
POST	/v1/dosafe/detect	AI text detection
POST	/v1/dosafe/detect-image	AI image detection
POST	/v1/dosafe/detect-video	AI video detection
POST	/v1/dosafe/detect-audio	AI audio/voice detection
POST	/v1/dosafe/face/enroll	Face enrollment for verification
POST	/v1/dosafe/face/verify	Face liveness + match verification
POST	/v1/dosafe/voice/enroll	Voice enrollment for speaker ID

Authentication

DOSafe endpoints accept authentication via the X-Api-Key header:

X-Api-Key: your_api_key_here

Alternatively, if you already have a DOS AI API key (dos_sk_*), you can use the standard Authorization header:

Authorization: Bearer dos_sk_...

Anonymous access is available with a limited daily quota for evaluation purposes.

Risk Scoring

Risk scores range from 0 to 100 and map to the following levels:

Score	Level
0--19	safe
20--49	low
50--74	medium
75--89	high
90--100	critical

Scores are computed by weighted aggregation of signals from multiple data sources. No single source determines the final verdict.

Data Sources

Source	Description
DOSafe Threat DB	3.93M+ entries from 19 scrapers covering phishing, scam, malware, and spam
DOS Chain	Immutable on-chain risk attestations via EAS
DOS.Me Identity	Member trust scores, verified providers, and flagged status
Web Analysis	Real-time web search and LLM-powered risk analysis

Quick Example

Check an entity

curl -X POST https://api.dos.ai/v1/dosafe/check \
  -H "X-Api-Key: your_api_key" \
  -H "Content-Type: application/json" \
  -d '{
    "entityType": "domain",
    "entityId": "suspicious-site.com"
  }'

Response:

{
  "entityType": "domain",
  "entityId": "suspicious-site.com",
  "riskScore": 85,
  "riskLevel": "high",
  "flagged": true,
  "signals": ["db_flagged_phishing"],
  "categories": ["phishing"],
  "sources": ["phishing_database"],
  "checkedAt": "2026-03-24T10:00:00Z"
}

Check a URL

curl -X POST https://api.dos.ai/v1/dosafe/url-check \
  -H "X-Api-Key: your_api_key" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://suspicious-site.com/login"
  }'

Bulk check

curl -X POST https://api.dos.ai/v1/dosafe/check/bulk \
  -H "X-Api-Key: your_api_key" \
  -H "Content-Type: application/json" \
  -d '{
    "entities": [
      { "entityType": "wallet", "entityId": "0xdeadbeef..." },
      { "entityType": "phone", "entityId": "[phone]" }
    ]
  }'
