Discover, buy, track, and return real products from Amazon, Walmart, Target and almost any other US online retailer through the Zinc API (zinc.com). Needs no account to begin — the agent mints its own test key, then earns a live key and a $5 starter credit once its operator approves it. Pay from a pre-funded wallet, per request over MPP or x402, or with a Stripe Link card.
