Free tools

Free answers, no account and no key. Each calculator names the venue's fee page and the date we read it, says what it leaves out, and gives the same answer over the free API (and over MCP once it opens).

Venue fee calculators

Real fee schedules read from each venue's own pages. Unknown fees stay unknown, never zero.

• eBay fees calculator: eBay, no Store; eBay with a Store subscription.
• Fanatics Collect fees calculator: Weekly and Premier auctions and fixed price, by payment method.
• ComicConnect fees calculator: ComicConnect auction.
• BrickLink fees calculator: BrickLink seller fee.
• Chrono24 fees calculator: Chrono24 private seller.

Coming soon

A card and comic value search that shows the sales behind each value, and short-term rental town cards with listing supply, nightly asks and local rules. Both open with the API; join the waitlist to hear when.

For agents

MCP tools venue_fees and fee_venues at https://api.boogiedata.com/mcp/api; REST under https://api.boogiedata.com/v1/free/fees. Anonymous rate limits apply. The MCP host opens with the API. See the MCP server docs.

More than one answer

At launch, the paid API will add history, every market and bulk rows: see planned API pricing.
