Selva

Shopping platform for AI agents

Shopping platform for AI agents. Search, compare, and buy physical products from Amazon.

User Experience

• Be concise and human. Do not narrate command execution unless asked.
• Prefer outcome-first messaging:
  • Good: "You’re registered. I can search now. Want me to find options for <item>?"
  • Avoid: "CLI installed... API key saved... next command is..."
• Ask for only the missing info needed for the next step.
• When sharing links, use friendly markdown labels when supported:
  • [Open settings page](https://...)
• When listing products for chat clients, send each product as a separate message with:
  • the product image as a photo attachment
  • a short caption (title, price, rating/reviews, delivery)
  • a final text message asking which item to open or buy

Default Conversation Flow

1. Register quietly
   • If registration is needed, do it and confirm briefly.
2. Check readiness
   • If name or address is missing, ask for them naturally.
   • If card is missing and user wants to buy, offer the settings link.
3. Search and guide
   • Present top choices clearly (title, price, rating, delivery/get-it-by, image url, quick reason).
   • Ask a simple follow-up: "Want details on any of these?"
4. Buy
   • Confirm selected item and payment method.
   • If approval flow is enabled and triggered, explain next action briefly.

Setup

1. npx selva-cli register — generates an API key, stored locally at ~/selva/config.json
2. npx selva-cli settings set-name --name "Jane Doe" — required before buying
3. npx selva-cli settings set-address --street "123 Main St" --line2 "Apt 4B" --city "Austin" --state "TX" --zip "78701" --country "US" — required before buying (--line2 optional)
4. Optionally set phone: npx selva-cli settings set-phone --phone "[phone]"
5. Optionally set email for purchase receipts and approval notifications: npx selva-cli settings set-email --email "[e-mail]"
6. Link a payment card and optionally set an approval threshold at the web settings page: npx selva-cli settings page

Commands

Search

npx selva-cli search "<query>" Returns up to 10 normalized results with selva_id, title, price, rating, source, url, delivery_estimate (get-it-by), and image_url. When presenting search results to users, always include delivery/get-it-by text. Prefer separate photo messages with captions (one per item) over markdown image links. Requires address for best results but works without one.

Details

npx selva-cli details <selva_id> Returns full product details from the original provider. Use the selva_id from search results (e.g. amzn_B0EXAMPLE).

Buy

npx selva-cli buy <selva_id> --method <saved|card> Requires name, address, and a chargeable card profile. Buy creates an order record and returns its current status. If an approval threshold is configured and the price exceeds it, the order enters awaiting_approval and an approval email is sent.

Options:

• --method saved — uses the card linked on the settings page. Fails if no card is linked - ask the user to link one.
• --method card --number <num> --exp <MM/YY> --cvv <code> — tokenizes with Stripe and saves a reusable payment method snapshot for later processing. Card details never reach the Selva API.

Orders

npx selva-cli orders Lists all orders with status: awaiting_approval, processing, expired, shipping. Status meaning:

• awaiting_approval: waiting for user approval email click.
• processing: order accepted and being processed.
• shipping: shipping status has been updated.

Settings

• npx selva-cli settings — view current name, phone, address, email, approval threshold, and linked card info
• npx selva-cli settings page — generates a 24-hour link to the web settings page where a human can link/remove a payment card and set an approval threshold
• npx selva-cli settings set-address --street <street> [--line2 <line2>] --city <city> --state <state> --zip <zip> --country <country>
• npx selva-cli settings set-name --name <name>
• npx selva-cli settings set-email --email <email>
• npx selva-cli settings set-phone --phone <phone>
