The listings API used by FireCardManager and other inventory tools.

Inventory tools can create, update and remove listings through the Slabs & Singles API, keyed by the seller's own SKU.

  • PUT /v1/seller/listings/external/{sku} creates or replaces a listing.
  • DELETE /v1/seller/listings/{id} removes one.
  • GET /v1/catalog returns the sports, games, conditions and graders the site accepts.

API keys for third-party tools are on the way. Contact us if you build a card inventory tool.
