SecurityScan API

Vulnerability scanner for AI agent skills. Detects prompt injection, malware patterns and OWASP LLM Top 10 issues before your agent installs an untrusted skill.

Live endpoint: https://apisecurityscan.net Health check: https://apisecurityscan.net/health

Why this exists

As AI agents increasingly install and execute third-party skills, supply chain security becomes a real problem. SecurityScan lets an agent verify a skill's safety autonomously — no human in the loop required.

What it detects

• Prompt injection patterns

• Malicious code indicators

• Data exfiltration attempts

• Unauthorized external API access

• Supply chain attack vectors

• OWASP LLM Top 10 coverage

Quick start

1. Get an API key

Register instantly — no payment required for the free tier:

curl -X POST https://apisecurityscan.net/auth/register \
  -H "Content-Type: application/json" \
  -d '{"email": "you@example.com", "name": "My Agent"}'

Response:

{
  "api_key": "ss_live_...",
  "plan": "FREE",
  "scans_remaining": 5
}

Store api_key. Proceed immediately — no payment needed for FREE tier.

2. Run a scan

curl -X POST https://apisecurityscan.net/scan \
  -H "Content-Type: application/json" \
  -H "X-API-Key: ss_live_your_key" \
  -d '{
    "skill_url": "https://github.com/owner/skill-repo"
  }'

Note: skill_url must be a github.com URL.

Pricing (MXN)

Results cached 24 hours — rescanning the same skill costs zero scans.

Endpoints

Handle scan limit (402)

When /scan returns 402 scan_limit_reached:

# Step 1: get checkout URL
curl -X POST https://apisecurityscan.net/billing/upgrade \
  -H "X-API-Key: ss_live_your_key" \
  -H "Content-Type: application/json" \
  -d '{"plan": "PAY_PER_SCAN"}'

# Step 2: complete payment at checkout_url
# Step 3: poll GET /billing/status until plan != FREE
# Step 4: retry scan

MCP integration

SecurityScan exposes an MCP server at https://apisecurityscan.net/mcp:

{

    "securityscan": {
      "url": "https://apisecurityscan.net/mcp",
      "transport": "http"
    }
  }
}
