Getting started

Product Data API is a metered REST API that returns fresh product price data by GTIN. You are billed only when the facet returns usable fresh data - invalid GTINs, missing products, and stale offers cost zero credits.

1. Sign up

Create a free account at product-data-api.com/auth/login. Sign in with Google, Microsoft, GitHub, or Apple. Your account receives 2,500 free credits automatically after first login.

2. Create your first API key

Go to Dashboard → API Keys and click Create key.

• Choose a descriptive name (e.g., dev-test).
• The clear secret is shown once. Copy it immediately and store it securely.
• Your key has the prefix pdapi_ and can be used in the Authorization header.

3. Query the price facet

curl -H "Authorization: Bearer pdapi_YOUR_KEY_HERE" \
  "https://api.product-data-api.com/api/v1/products/0885909950805/price"

Replace 0885909950805 with a real GTIN-13 or GTIN-14.

4. Understand the response

A successful response looks like:

{
  "meta": {
    "requestId": "req_01HXYZ",
    "gtin": "885909950805",
    "facet": "product.price",
    "billable": true,
    "creditsConsumed": 5,
    "creditsRemaining": 2495,
    "reason": "fresh-offer",
    "responseTimeMs": 34
  },
  "data": {
    "bestPrice": {
      "price": 699.0,
      "currency": "EUR",
      "merchant": "TechStore FR"
    },
    "offerCount": 3,
    "freshness": {
      "oldestOfferDays": 4,
      "newestOfferDays": 1
    }
  }
}

If no fresh data exists, billable is false and creditsConsumed is 0.
