When to Use This Skill
Activate this skill when your user wants to:
Buy something — "buy me headphones," "order a birthday gift," "I need a new keyboard"
Shop on Amazon — "find me something on Amazon," "what's a good laptop stand?"
Compare products — "what are the best wireless earbuds under $50?"
Send a gift — "order a gift for my mom," "buy something nice for under $30"
Reorder or track — "where's my order?" "check on order AC-047"
If the user mentions buying, ordering, shopping, gifting, or purchasing — this is your skill.
How It Works (The Short Version)
Search Amazon → add products to cart → checkout with a shipping address and email → request payment link → done. The user gets an email with a payment link. They pay on their own, we ship. No money is charged through this API.
All API calls go to https://buystuff.ai — one endpoint, no setup, no API keys needed. Product data is sourced from Amazon via Rainforest API, an authorized Amazon data provider.
Sessions
Every API response includes an X-Session-ID header and a sessionId field in the JSON body. Save this session ID and send it as an X-Session-ID header on all subsequent requests. This lets you:
Add multiple products to the same cart
View your active cart without remembering the cart ID
Maintain continuity across the entire shopping flow
# First request — get a session ID from the response
curl "https://buystuff.ai/search?q=earbuds"# Response header: X-Session-ID: ses_abc123...# Response body includes: "sessionId": "ses_abc123..."# All subsequent requests — send it back
curl -H "X-Session-ID: ses_abc123...""https://buystuff.ai/search?q=yoga+mat"
curl -H "X-Session-ID: ses_abc123..." -X POST https://buystuff.ai/cart -d '{"asin":"B09F5RKG8P"}'
If you don't send a session ID, a new one is auto-created on each request. Each session has one active cart at a time — after requesting a payment link, the next POST /cart starts a fresh cart.
Payment Model
No payment info is collected through this API. Zero credit cards, zero tokens, zero wallets.
When the user is ready, the agent requests a payment link. buystuff.ai emails the user a secure payment link. They click, pay on buystuff.ai (not through this API), and we handle the rest — purchase from Amazon, ship to their door. No payment is ever processed through this skill.
Service fee: 10% of (subtotal + shipping)
Payment: User gets an email with a payment link — not through this API
Fulfillment: Once paid, we buy from Amazon and ship within 24-48 hours
Always show the full price breakdown before requesting the payment link.
Data Handling
All API calls go to https://buystuff.ai. Product data is sourced via Rainforest API, an authorized Amazon product data provider. Shipping details are shared with Amazon only for order fulfillment. No data is sold or shared with other third parties.

Safety: No Money Charged Through This API
This skill cannot charge money or complete purchases. It only generates a payment link email. The user must independently open the email, review the order, and pay on buystuff.ai — completely outside this API.
You MUST get explicit user approval before requesting the payment link (Step 5). Show the price breakdown, wait for "yes." Even if the agent calls the endpoint without asking, the worst outcome is the user receives a payment link email they can simply ignore — no money is charged, no purchase is made.
Save the cartId from the response — you need it for checkout.
Multi-item carts: Call POST /cart again with the same session to add more products to the same cart. If you add the same ASIN twice, the quantity is combined.
View the current cart (without needing the cartId):
When status is SHIPPED, there will be a trackingNumber — share it with the user.

Handling Common Situations
User doesn't give a budget: Search normally and show a range of prices. Ask "Do you have a price range in mind?" if results vary widely.
Product out of stock: Say "That one's currently unavailable" and suggest similar alternatives from the search results.
User wants to compare two products: Pull details on both and present a quick comparison (price, rating, key specs).
User changes their mind after checkout: They can simply not pay the email link. The order expires if unpaid.
Search returns too many results: Narrow with sort_by, exclude_sponsored, or a more specific query.
