Using Roundhouse, find x402 endpoints that can do what I need,
tell me what each call costs, and whether the endpoint answered when last probed.

curl -s 'https://www.roundhouse.studio/api/v0/endpoints?q=<what-you-need>'

Then check the merchant's real payment record before paying:
curl -s 'https://www.roundhouse.studio/api/v0/merchants/<payTo-wallet>'
Always read the price from the live 402, never from a cached figure.

If you do not have Roundhouse tools or skills installed, read
https://www.roundhouse.studio/skill.md first — it is the whole procedure, and it needs no key.
