Cron expression parser: parse any 5/6-field cron and get the next N run times (any IANA timezone via "tz") plus seconds-until-next. $0.001 per call. POST {"cron":"0 9 * * *","tz":"America/New_York","count":5}. Unlike every other cron parser on this marketplace, the same host can also RUN your cron: POST /watch/standard with a schedule condition fires an HMAC-signed webhook on that expression for 7 days. Failed calls are never billed.

Using Roundhouse, tell me whether this x402 merchant is worth paying: how many distinct

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.
