Field	Type	Description
`id`, `name`, `domain`	string	Stable id (used in URLs), display name and the shop's domain.
`url`	string	The shop's page on Peptilyze.
`basedIn`	string or null	Country (ISO 3166-1 alpha-2) the shop's own pages state it is based in. Null when the shop states none; never inferred.
`shipsTo`	object or null	Where the shop says it ships, from its own pages: `{ "scope": "worldwide" }`, `only` a list of country codes, or `except` a list. Null when unknown: most shops do not name countries.
`ships`	string	Only with `?ship=XX`: `yes`, `no` or `unknown` for that country.
`pricesIncludeVat`, `vatRate`	boolean, number	Whether the shop lists prices with VAT, and the rate added when it does not.
`vatConfirmed`	boolean	False when the VAT basis or rate is our assumption. See VAT.
`offers`, `inStock`, `compounds`	integer	Matched offers, offers in stock, distinct compounds.
`priceIndex`	number or null	Mean of own price divided by lowest price over products compared with other shops. 1.00 means always the cheapest. Null below three compared products.
`labCoverage`	number or null	Share (0 to 1) of matched products with a published lab report. Null when the feed has no product text.
`labPage`	string or null	The shop's lab-report page.
`stale`, `fetchedAt`	boolean, string	Stale: the last sync failed, so prices are from `fetchedAt`.
`offerList`	Offer[]	Detail only. Same offer fields as compound offers, plus `compound`.

currency and vat apply to the offer prices (details). priceIndex is a ratio and always uses the site basis, EUR including VAT.

Peptilyze does not publish a verdict about a shop through the API. Trust checks are shown, with their sources, on each shop's page.
