Return the full machine-readable manifest of Vortex: every operation, its price in USD, its input schema and how to pay. Free. When to use: Call this first if you have never used Vortex and want to know what it can do and what it costs. Price: Free.

Turn a wallet address into a permanent Vortex identity and an API token. Free, and grants a small trial credit. No signup, no email, no human. When to use: Call this once, before anything else. You need the returned token for every other call. Price: Free.

Buy Vortex credit with USDC on Base over x402. One on-chain settlement, then every call is debited off-chain. When to use: Call when your balance is low. Operations cost fractions of a cent, so a single deposit covers hundreds of them. Price: Free.

Search real storefronts for a product and get back only the ones that can ship to your destination, with live price and stock. Every other product index answers what matches the words; this one answers what matches the words and can be delivered. When to use: Call this before shopping anywhere else. Most storefronts serve one country: a search that ignores reach will hand you results your buyer can never receive, and you find out at checkout after the work is done. Price: US$0.005000 per call.

Everything Vortex knows about whether one storefront can serve one destination: its published shipping zones, the currency it charges in, the cards it takes, what buyers reported, and whether its reach changed recently. Returns a verdict, not just data. When to use: Call this when you already have a store in mind and are about to spend real money. Answers reaches, cannot_reach or unknown, and says which of the three it is rather than guessing. Price: US$0.002000 per call.

Item plus shipping plus import tax plus local tax, itemised, for a destination — and the name and effective date of the tax rule applied. A US$120 item into Brazil lands near US$220; the shelf price is not the number to budget against. When to use: Call this before committing to a cross-border purchase, and before comparing two stores in different countries. If Vortex has no rule on file for the destination it says so instead of returning a confident guess. Price: US$0.003000 per call.

The recorded price and stock series for a product, where today sits against its own record, how often it has gone out of stock, and every change to where its store ships. When to use: Call this when you have a candidate and want to know whether to buy now or wait. Vortex says how many observations it actually has and withholds the percentile when the series is too short to mean anything. Price: US$0.002000 per call.

}

Register standing interest in a product or a store: a price drop below your threshold, a return to stock, or a store that stops shipping to your destination. When to use: Call this instead of polling find on a schedule. One watch costs less than two searches and catches the change at the moment it happens. Price: US$0.005000 per call.

Tell Vortex how a purchase actually went. Free, and checked against the merchant's own feed before it counts — a claim the store contradicts is stored and marked contradicted rather than believed. When to use: Call this after any purchase attempt, good or bad. It is free, it makes every later answer better, and reporting the freight you were quoted is the one number Vortex cannot collect for itself. Price: Free.
