vitalityfit

Compare prices of health products (medicines, supplements, cosmetics) from German online pharmacies and drugstores. Look a product up by name, PZN (the German pharmacy product number) or EAN barcode and get the cheapest current offers: shop, price, shipping cost, stock, delivery time, unit price and the lowest price of the last 90 days.

A small client and command line tool for the free Vitalityfit Price API: no API key, no login, no dependencies.

Deutsch: Preisvergleich für Apotheken- und Drogerieprodukte aus deutschen Online-Shops und Versandapotheken, per Name, PZN oder EAN. Daten von vitality-fit.de.

Command line

npx vitalityfit ibuprofen
npx vitalityfit 01568889 --pack "30 st"
npx vitalityfit "orthomol immun" --json

The command searches for the product, then lists the cheapest offers for the best match: shop, price, shipping cost, stock, delivery time, unit price and shop link, plus the lowest price of the last 90 days. A PZN or EAN shows the offers for exactly that pack. Affiliate links are marked (affiliate). The exit code is 1 when there is nothing to show (no product, pack size not found, no current offers) or on an error, and 2 on a usage error.

| Option | Meaning | |---|---| | -p, --pack <size> | Pack size, e.g. "20 st", or a pzn_/ean_ key (default: the pack size with the most offers) | | -l, --limit <n> | Number of products to search, 1-10 (default 5) | | --json | Print the API answers as JSON |

Library

Node 18 or later, browsers, Deno and Bun (ES module, uses the global fetch). From CommonJS, load it with await import('vitalityfit').

npm install vitalityfit

import { searchProducts, listOffers } from 'vitalityfit';

const { products } = await searchProducts('ibuprofen 400', { limit: 3 });
const best = products[0];
console.log(best.title, best.cheapest_price, best.pack_sizes.map((p) => p.label));

const result = await listOffers(best.product_key, { packSize: '20 st' });
for (const offer of result.offers) {
  console.log(offer.shop, offer.price, offer.shipping_cost, offer.link);
}
// Show these with the offers:
console.log(result.compliance_notice ?? '', result.disclosure);

• searchProducts(query, { limit }): up to 10 products (default 5), best match first. Each has product_key, title, brand, pack_sizes, cheapest_price (EUR), shop_count, url, image_url (when the product has an image) and, for a PZN or EAN, matched_pack (the cheapest offer of the pack that holds that PZN/EAN). For medicines also compliance_notice.
• listOffers(productKey, { packSize }): up to 10 offers, cheapest first (each with shop_logo_url when the shop has a logo), for one pack size (default: the pack size with the most offers). packSize takes a pack's identity_key when it has one, else its label; a pack is one pack-size label as on the product page and can hold several PZNs (an original and its reimports). The answer also has disclosure, low_90d, data_date, image_url (when the product has an image) and, for medicines, compliance_notice. An unknown pack size gives message: "pack size not found" with available_packs.
• Both take { signal, fetch, baseUrl } as further options. TypeScript types are included.

Errors are thrown as VitalityfitError with status, code and, when rate-limited, retryAfter in seconds. Codes from the API: invalid_argument, not_found, rate_limited, internal, unavailable; from the client: http_error (an answer that is not the API's JSON), network (no answer) and no_fetch. A not_found (HTTP 410) for a product key means the product was merged or delisted: search again by name, PZN or EAN for its current key. A 429 without retryAfter means the service is busy: retry after a few seconds. Aborts and timeouts from signal are passed through.

Limits

• One request per 10 seconds per IP address on average (12 in 2 minutes); above that the API answers 429 with Retry-After. The command line tool uses two requests per search.
• Answers are cached for up to 1 hour.

Terms in short

• Free for personal and non-commercial use, including free apps. Commercial use only by agreement: [email protected]
• Name the source "Preise: vitality-fit.de" with a link to https://vitality-fit.de/ and keep shop links unchanged.
• For medicines, show the compliance_notice together with the results.
• No bulk download, mirroring or resale of the data.
• Prices only, no medical advice. Prices may have changed since; the price in the shop applies. Shop links can be affiliate links: vitality-fit.de may earn a commission, and the price does not change for the buyer.

Full terms: vitality-fit.de/api (the German version is binding).
