Aday

Aday is a direct-to-consumer sustainable fashion brand founded in 2015 in New York City by Nina Faulhaber and Meg He. It designs technical, long-lasting capsule wardrobes built for outfit repetition, using custom recycled fabrics (including post-consumer recycled plastic) and plant-based, beechwood-derived materials produced in closed-loop processes. Aday has raised more than $10 million in venture capital, is backed by Cowboy Ventures, and has been named one of Fast Company's Most Innovative Companies, with coverage in Vogue, Refinery29, and Conde Nast Traveler. The company sells globally through its Shopify-powered storefront at thisisaday.com and does not publish a public developer API. This profile was created as an API Evangelist network stub from Cowboy Ventures' portfolio and enriched with company identity and domain-security signals; the storefront returned a Shopify "store is unavailable" lock at the time of the enrichment probe.

Aday is profiled on the APIs.io network. Tagged areas include Company, Consumer, Fashion, Apparel, and E-Commerce.

Aday’s developer surface includes FAQ, support, and 3 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/aday: open an issue to ask a question, or submit a pull request to add artifacts.
