Smynd API

One product. Every price — as an API. Search products, list their variants and get a normalized price comparison across merchants. Free to use, no key required.

OpenAPI 3.0 spec →

Endpoints

GET /api/products ?q=biofinity

Full-text product search. Returns opaque product IDs — always discover IDs here, never construct them.

GET /api/products/{id}

Product details: brand, attributes, images, lifecycle status.

GET /api/products/{id}/variants

Purchasable variants (pack sizes, prescription variants) with their variantKey.

GET /api/products/{id}/prices ?country=DE&quantity=1

All variants with raw offers plus a normalized comparison: unit price, shipping, totals — deduplicated per merchant, sorted by unit price incl. shipping.

GET /api/products/{id}/variants/{variantKey}/prices ?country=DE

Same comparison for a single variant.

GET /api/products/{id}/variants/{variantKey}/price-history ?merchantId=…

Price change history per merchant and variant.

LLM integration

The OpenAPI spec carries x-llm-instructions so agents can use the API without a UI. The essentials:

Product IDs are opaque — resolve them via GET /api/products?q=…, never guess them.
Answer price questions from comparison.entries: already normalized, deduplicated per merchant and sorted by unit price incl. shipping.
Pass quantity (1–99, default 1) to compare a specific order quantity.
The purchase link is the raw offer with the matching offerId.
