For sellers choosing where to sell

Compare what you would keep from the same sale on different marketplaces and auction houses, from each venue's published fee schedule, before you list.

The data

Real fee schedules, read from each venue's own fee pages, with the date we read them. Fees a venue does not publish show as unknown, never zero.

An example question

If this card sells for 250 US dollars, what do I keep with and without an eBay Store?

Where to start

1. List the venues and their IDs with fee_venues.
2. Ask venue_fees for one price at up to five venues at once.
3. Open each venue's source link before a large sale; fees change without notice.

The calls below are step 2. No key is needed; the REST call works now, the MCP tool when the MCP server opens.

REST

curl 'https://api.boogiedata.com/v1/free/fees?venue=ebay%2Cebay_store&price=250'

MCP tool venue_fees

{
  "venue": "ebay,ebay_store",
  "price": "250"
}

Use the IDs these calls return. See the quickstart.

Which plan

The fee calculators are free and need no key. Fee history by venue is planned for the paid API. See pricing.
