Every computed price comes with a check link

Priced answers now carry receipt.check_url. Send it with a price you quote, and the buyer or their agent can confirm it was computed on Last Price, with no account and no key.

The check page for a computed price, showing it was issued by Last Price, when it was computed and until when it holds

When you quote a price that Last Price computed, the buyer has had no way to tell it came from us. Now every priced answer from the API, MCP, batch, pricing chains and pay per call carries receipt.check_url.

  • Send the link with the price. Whoever opens it sees the price, when it was computed, and whether it still holds, with no account and no key. A changed link says it is not genuine.
  • Honest about what it shows. The page says the seller chose the pricing function, and offers the buyer a free, independent check of the price.
  • Nothing private travels with it. The page names no workspace, pricing function or input, and it does not commit you to sell at the price.
  • Agents can read it too. Add ?format=json or ?format=text, or ask for JSON in the Accept header.
