The Paragon Hub is where capsuleers sell the ship designs they build in SKINR. In the client it is a list you walk one page at a time, with no way to ask the question every buyer actually has: which designs exist for the hull I fly, and which of them is cheapest. This page reads the whole public market from Fenris Creations' ESI and lets you narrow it by hull, ship class, tier, currency and listing state.
Half the market quotes in PLEX and half in ISK, which makes the two halves impossible to compare in-game. Every PLEX asking price here is also shown converted at the PLEX reference price, so a single ordering by price covers the entire market rather than one currency at a time.
Opening a listing shows the design itself, slot by slot: the nanocoatings in the primary, secondary, detailing and tech slots, the pattern and its material, each with its own name, rarity grade and finish, plus the blend mode the author chose. The component thumbnails are the real ones served by the EVE image server, not approximations, and the hull and the author both link through to their pages on the site.
Listings stay visible after they sell out, expire or are withdrawn, so the state filter doubles as a record of what the market has already absorbed. Designs are read once and kept: a SKINR identifier is a digest of the design, so the same identifier always describes the same colours in the same places.
