API Reference

Scandar exposes a REST API for scanning, fixing, and Guard runtime operations. All endpoints are under /api/v1.

Base URL

https://api.scandar.ai/v1

Format

JSON (application/json)

Auth

Bearer token (API key)

Authentication

All API requests require an API key passed as a Bearer token in the Authorization header. Create and manage API keys in Dashboard → API Keys.

curl https://api.scandar.ai/v1/scan \
  -H "Authorization: Bearer sk-your-key-here" \
  -H "Content-Type: application/json" \
  -d '{ "text": "...", "scan_type": "skill" }'

Warning

Never expose your API key in client-side code or public repositories. Use environment variables or a secrets manager. Keys can be rotated in the dashboard at any time.

Key scopes

read	GET endpoints only — results, findings, reports
scan	POST /scan — submit scans
fix	POST /fix — AI-powered remediation (Pro+)
guard	All /guard/* endpoints — runtime inspection

When rate limited, the API returns 429 Too Many Requests with a Retry-After header indicating seconds until the limit resets.

Error Codes

400	Bad Request — missing or invalid parameters (e.g. no text or file provided)
401	Unauthorized — missing or invalid API key
403	Forbidden — your plan does not include access to this endpoint (e.g. /fix requires Pro)
415	Unsupported Media Type — content type not recognized; use application/json or multipart/form-data
429	Too Many Requests — rate limit exceeded; check the rate_limit field in responses
500	Internal Server Error — something went wrong on our end

Code Examples

Scan a file and gate on trust score

SCORE=$(curl -s -X POST https://api.scandar.ai/v1/scan \
  -H "Authorization: Bearer $SCANDAR_API_KEY" \
  -d "{"text": "$(cat my-skill.md | jq -Rs .)", "layer2": true}" \
  | jq '.trust_score')

if [ "$SCORE" -lt 70 ]; then
  echo "BLOCKED: trust score $SCORE < 70"
  exit 1
fi

Scan + auto-fix in one call

# Step 1: scan
SCAN=$(curl -s -X POST https://api.scandar.ai/v1/scan \
  -H "Authorization: Bearer $SCANDAR_API_KEY" \
  -d "{"text": "$CONTENT"}")

SCAN_ID=$(echo $SCAN | jq -r '.scan_id')
FINDING_IDS=$(echo $SCAN | jq -r '[.findings[] | select(.severity=="critical" or .severity=="high") | .id]')

# Step 2: fix
curl -X POST https://api.scandar.ai/v1/fix \
  -H "Authorization: Bearer $SCANDAR_API_KEY" \
  -d "{"scan_id": "$SCAN_ID", "finding_ids": $FINDING_IDS}"
