1. 1

   Check a real recall yourself

   Open the live check and tap “Harppa high chair”. It is CPSC recall 26-061: model BHC001, recalled only in batch 202408.

   Open the live check →
2. 2

   Try the edge cases

   Same model, other batch: KEEP HELD, because the recall names one batch. OCR slip “BHCOO1”: still matches. An unknown model: NO_MATCH, and it never says “safe”.

   Run it from your terminal

   Same index, no key:

   Give the check to an AI shopping agent

   The same check is an MCP tool, recall_check. Point any MCP client at this URL, or call it directly:

   curl -s https://www.lullabuy.tech/api/mcp -H 'content-type: application/json' -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"recall_check","arguments":{"model":"BHC001","batch":"202408"}}}'Copy

   Shop by voice or text

   Say “a bassinet for my newborn under $80, pickup in Atlanta”. Gemini reads the request, real listings come back pre-screened (red, amber, or photo check passed), and “Buy with our agent” places a Trusted Agent Protocol-signed Visa hold you then settle on /pickup.

   Hold real money, then settle it at pickup

   On /pickup, type Visa's sandbox test card (4111 1111 1111 1111, any CVV, a future expiry) into Visa's own Microform fields, pick a listing and press Agree: a real Visa Acceptance sandbox authorization is created with capture off (HELD). Type BHC001 / 202408 and the hold is REVERSED at Visa; type any model with no recall and it is CAPTURED. The Visa ids are on screen.

   Get the item's passport

   When a clean label captures the payment, a Solana devnet transaction stores the SHA-256 of the pickup record (no personal data on chain). The passport page reads it back and checks the signer, the transaction and the hash.

   Pay again with a saved card

   Tick “Save this card with Visa” on the first hold. Next time, “Use my saved card” pays with Visa's Token Management Service; the card stays in Visa's vault. When Visa applies a card-linked offer, the hold is the discounted amount and the saving is shown.

    The phone app

    The same product as an iOS and Android app (Expo): shop, scan a label with the camera, and the deal board, all on this deployment's API. Source in mobile/; run it with Expo Go.

    Watch it from the seller's side

    After you press Agree on /pickup, a QR code appears. Scan it with a second phone: the seller's live view (MongoDB Atlas) follows the same deal to CAPTURED or REVERSED, with the reason. Every deal is also on the board.
