API documentation

Get started

1. Sign in with Google.
2. Add API credits in your dashboard, starting at $1.
3. Generate an API key and store it as AI_DETECTOR_API_KEY.

# Save {"text": "your full text (50–5,000 words)"} in request.json
curl https://jev-ai-detector.com/api/v1/detect \
  -H "Authorization: Bearer $AI_DETECTOR_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: check-001" \
  --data @request.json

Request

Send JSON and authenticate with Authorization: Bearer YOUR_API_KEY. Keep your key in server-side code.

Response

{
  "label": "human",
  "probabilities": {
    "ai": 0.12,
    "human": 0.88
  },
  "cost_usd": 0.005
}

The higher probability wins. cost_usd is the charge for this check; the example is for 1,000 words.

Pricing

$0.0005 per started 100 words. Add as little as $1. The website checker is free.

100× cheaper than Pangram 4’s standard API. Pangram charges $0.05 per 100 words; ours costs $0.0005 for the same length.

No subscription, credit expiry, or daily API allowance. Each successful request is charged by text length, including cached results. Failed checks are not charged.

Retries

Send an Idempotency-Key to safely retry the same text without paying twice. Keep it unchanged for retries and use a new one for each new check. A reused key with different text returns 409. Retry records are retained for 30 days.

X-Idempotent-Replay: true means the response is a replay and no new charge occurred. The JSON retains the original check’s cost. X-Request-ID identifies the check.

If a request is still processing, wait before retrying it. For 429 responses, follow Retry-After.
