These are **Pro** tools: they're the ones that pay for themselves. ## eBay — one-click listing Connect your eBay account once (official OAuth — Magpie stores encrypted tokens, never your eBay password), then publish any Magpie listing to eBay in one tap: * Title, photos, condition, price and quantity come straight from your Magpie listing. * The external listing is tracked next to the Magpie one, so you always see where a card is exposed. * Business policies (payment/shipping/returns) come from your eBay account — set them up there once. ## Cardmarket — stock file export Cardmarket closed its API to new applications, so no app can list there directly anymore. Magpie does the next best thing: a **Cardmarket-ready stock CSV** of your active listings — conditions and languages already mapped to Cardmarket's scale — that you upload in their stock manager. Thirty seconds instead of retyping your whole stock. ## Priced to sell, not to sit Every listing shows the oracle's fair value and band next to your asking price while you type it. Price alerts (Pro) watch the market for you — "tell me when this hits €X" — so you list at the right moment, and the automated fake-detection keeps obviously mispriced listings flagged for review without blocking anyone. {% hint style="info" %} **Where this is going:** more channels ride the same connector pattern — see the [roadmap](/project/roadmap.md). Cardmarket API access, if it ever reopens or a partnership lands, plugs into the same place. {% endhint %} --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.magpie.gg/the-app/connectors.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
