Paid to
0xE1F27E03BDBAd7a70055B52Af30B2dB9537F43FdThe wallet the 402 directs payment to. Its whole payment record — every payer, every chain — is on the merchant page.
Asset 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913
Provider
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.

Captured by the enrichment pass, not read just now. Prices can change — always read the 402 the endpoint answers with.

Nothing indexed for this service or its provider yet. Not a claim that it is unused — only that we hold no record. Verified volume counts only settlements with an on-chain EIP-3009 marker.
Show the promptHide the prompt
Using Roundhouse, look up the x402 service zkbcy7ja.nx.link 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=zkbcy7ja.nx.link'
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://zkbcy7ja.nx.link/v1/wallets/{address}/nfts, 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. Mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402,
or use an organization key from https://roundhouseai.io/dashboard/team.
If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
