AuctionHelper is being rebuilt for the modern eBay operator. A pricing-intelligence and listing-management platform focused on the categories where market comps matter most — graded cards, autographs, memorabilia, sealed wax, and adjacent collectibles.
Account holders — enter your credentials to access the seller dashboard.
Built by an eBay operator, for eBay operators. Each capability below is being staged in throughout 2026 as we rebuild for the modern seller.
Look up recent sold prices for items across your inventory and price new listings against real market activity — not guesses.
Draft-first workflow across eBay and adjacent channels. Publish, revise, and end listings from a single dashboard.
Informed proxy bidding on auctions with visibility into recent sold comps for comparable items. Bid confidently in comp-sensitive categories.
Our launch categories are the ones where a single missed comp costs real dollars. General-purpose tooling supports every eBay category.
PSA · BGS · CGC · SGC — grade-specific filters, set / year / player matching
JSA · PSA/DNA · Beckett authentication — signer disambiguation, framed vs. loose
Jerseys · balls · programs · tickets — condition-aware pricing
Trading card packs and boxes — set + year matching against comparable seals
CGC · CBCS graded comics — series, issue, and grade-tier matching
Sealed / CIB / loose — VGA / WATA grade filters, region and platform variants
First editions, signed books, printed programs — condition and edition matching
All other eBay categories with keyword + condition + price-band filtering
Every step of the flow is designed around the operator's actual workflow — not a generic dashboard bolted onto an API.
OAuth-based connection with granular scope permissions. Read-only by default — nothing modifiable until you explicitly opt in.
Your active inventory syncs into the dashboard. We fetch prices, comps, and category assignments automatically.
Every listing gets a "suggested price" panel showing median/mean/range of recent sold comps for comparable items.
Accept, adjust, or reject pricing recommendations. One click pushes updates back to your eBay account.
We take marketplace policies, data handling, and security seriously. Our infrastructure is designed to survive an audit, not just pass a checklist.
Verified endpoint receives and processes eBay account-deletion notifications, purging user data within the required window. SHA-256 challenge-verified.
Public tool surfaces request read-only OAuth scopes. Write scopes are opt-in per-action, with a separate consent screen for publishing operations.
Every stored row is tied to the querying user. No cross-user data leakage, no aggregated market-intelligence exports, no third-party data sharing.
All cached marketplace data respects eBay's retention rules. Freshness markers on every row; automated purge on cache expiry.
Every API call logged with timestamp, calling user, query parameters, and response summary. Available for eBay audit on request.
OAuth refresh tokens encrypted at rest with Fernet. Keys held in AWS SSM SecureString. TLS 1.2+ enforced on all external traffic.
