Product-Label Artwork Compiler
Compile a structured product-label spec (dimensions, EU FIC or US FDA ruleset, ingredients/allergens, nutrition, GS1 barcode, brand style) into a deterministic print-ready PDF with trim/bleed/safe boxes and embedded fonts, an SVG proof, a dieline, and a report auditing x-height legibility, allergen emphasis, nutrition order, and barcode check digits/quiet zones. Not a legal review of packaging compliance.

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. 13 snapshots so far. Verified volume counts only settlements with an on-chain EIP-3009 marker.

Using Roundhouse, look up the x402 service Product-Label Artwork Compiler 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=Product-Label%20Artwork%20Compiler' 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://label.api.williamrobinson.dev/v1/label/compile, 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.
