Is this claim already taken by a competitor? Use when the user is choosing a positioning, a tagline or a message and asks whether competitors already say it, whether a claim is crowded or open, or who has moved onto it recently. Whether 3-5 competitors' home pages make a claim today, lead with it or mention it, and whether they did a year ago. No page text is returned. If its pre-declared control fails, the run refuses and nothing is charged. Pay per run with x402 (USDC on Base) or MPP.
