# Agentcard changelog: new features, updates, and fixes

> Weekly updates on what's new in Agentcard: Purchase API merchants, wallet changes, developer tools, and fixes that affect how you build.

<Update label="August 18, 2026">
  ## Purchase API merchant lineup, confirmed

  We rechecked which merchants agents can actually buy from through the [Purchase API](/purchase/purchase-api), and updated the list on that page to match what's live today. If you build against `/buy`, this is the full set your agents can shop from right now:

  * **Retail:** Amazon, Walmart, Target, Best Buy, Home Depot, Lowe's, Macy's, Wayfair, Staples, Kohl's, and B\&H Photo.
  * **Delivery and groceries:** DoorDash, Good Eggs, and Locale.
  * **Travel:** flights.

  What this means for you: if a merchant isn't on this list, `/buy` won't place an order there yet. When you send an `ask`, the API picks a merchant from this set, and if the merchant needs the user to link an account first, the response tells you.

  We're still adding more merchants. To see what a full purchase looks like end to end, try [your first order in sandbox](/purchase/first-order-in-sandbox).
