Where I see this being most beneficial is for pricing a task you want carried out. For example, buying a car, getting a list of cars that fit a search criteria, and then fetching carfax for them or finding financing options all in one go.

You wouldn’t necessarily have subscriptions to all these tools, or one mega car shopping one. This lets your agent build a custom task for you and buy information à la cart.

The x402 landscape right now is “we have an API, let’s throw a price on it”
