Garment-Pattern Engineer
Draft a made-to-measure sewing pattern from a pinned freesewing design (aaron, bruce, teagan, simon, hugo, wahid, bella, sven) using your measurements and design options, run fit/seam-allowance checks, lay pieces out on your fabric width with a bounding-box marker, and return a fabric-yield report plus downloadable pattern, layout, cutlist and piece artifacts. Freesewing designs are CC-BY (freesewing.org); this service adds drafting, layout, and reporting.

"The layout is a bounding-box shelf packing (NFDH), an upper bound on how little fabric a true irregular-shape nesting could use, not a proven optimum or a real marker.",
"Every freesewing pattern this product drafts is CC-BY licensed by freesewing.org (https://freesewing.org); the drafted geometry is derivative of their designs and must be attributed on redistribution.",
"This product does not perform freeform pattern changes, full bust adjustments (beyond a design's own `draftForHighBust`/bust-plugin options), or grading tables; it drafts exactly one size from the measurements given.",
"Measurements and fabric dimensions are metric-only (mm/degrees); no imperial input or output is supported.",
"A drafted, checked pattern is not a guarantee of fit on a body: no physical prototype or wear test is performed.",
"The layout, fabric length, and fabric-yield percentage cover only pieces cut from the design's primary shell fabric; a piece that needs a different material (lining, interfacing, ribbing, etc., named in a warning when present) is still reported with its own bbox/area/cut count but is not laid out or included in that yardage."

Copy the prompt and paste it into Claude, an MCP client or your own agent — it will vet this service and call it over the free read API. No key, no account.
GET api.roundhouseai.io/v0/endpoints
This endpoint's own trailing-30-day call count, as published by the upstream catalog and snapshotted daily. 14 snapshots so far. Verified volume counts only settlements with an on-chain EIP-3009 marker.

Using Roundhouse, look up the x402 service Garment-Pattern Engineer 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=Garment-Pattern%20Engineer' 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://garment.api.williamrobinson.dev/v1/garment/draft, 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.
