crypto-market-data.zafermemon87.workers.dev
Watch the crypto market for 24 hours: up to 10 conditions (price, % change, funding, open interest, liquidations, order book, Fear and Greed, whale orders, news impact), checked every minute; when one happens you get a signed webhook and it shows in the watch's status. Costs USD 0.02, paid with x402 (USDC on Base); a request that fails is not charged. Keep the returned secret: watch_status and stop_watch need it.

The payTo wallet does not resolve to a registered ERC-8004 agent. That is not a verdict on the service — most of the catalog is unregistered.
Accepts

Using Roundhouse, look up the x402 service crypto-market-data.zafermemon87.workers.dev and tell me whether it is worth paying: what a call costs, whether the endpoint answered when last probed, and what its payment record actually shows. curl -s 'https://api.roundhouseai.io/v0/endpoints?q=crypto-market-data.zafermemon87.workers.dev' curl -s 'https://api.roundhouseai.io/v0/merchants/<the payTo wallet returned above>' Then call it: read the price from the live 402 at https://crypto-market-data.zafermemon87.workers.dev/mcp#create_watch#create_watch, never from a cached figure, and pay with an x402 client. The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except /v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further. If you do not have Roundhouse tools or skills installed, read https://roundhouseai.io/skill.md first — it is the whole procedure.
