Slabline HQ

Any graded slab, valued in your channel — in seconds.

Type /value cert:<number> with the certification number printed on any slab label. Slabline verifies the cert with the grading company and posts the card right in the channel: year, set, player, grade, slab photo, and its current market value drawn from real comparable sales — not list prices, not guesses.

Works with PSA, BGS, SGC, CGC, and TAG — the grader is auto-detected from the cert, or pass it explicitly with the optional grader option.

Built for card communities: • Buy/sell/trade channels — settle "what's it worth?" without leaving Discord • Breaker servers — price slabs live while chat watches • Pricing debates — end them with actual comps

Why mods say yes: • Zero permissions. The bot only registers slash commands (applications.commands scope). It cannot read your messages, cannot post on its own, and has no access to your server beyond answering when asked. • No setup. Add it once and /value works in every text channel immediately — nothing to configure. • Misses stay private. A typo'd cert answers only the person who asked (ephemeral). The channel only ever sees clean, successful lookups. • Free. No premium tier, no vote-gating.
