Sunday

Sunday (Sunday Lawn Care, getsunday.com) is a direct-to-consumer, subscription lawn and yard care brand. It builds a personalized annual plan for each customer's exact lot from satellite imagery, soil data, and local climate patterns, then ships pesticide-free, phosphorus-free fertilizer, weed control, grass seed, and pest-control products on a seasonal cadence. Plans include Sunny AI guidance and Yard Advisor expert support, plus regional lawn-care guides for 1,700+ US cities. Sunday is a consumer commerce company rather than an API provider: it publishes a machine-readable llms.txt for agents and runs an internal application API (api.getsunday.com), but exposes no public developer portal, OpenAPI, SDKs, or documented API surface. It was surfaced as a portfolio company of Bond Capital and added to the API Evangelist network.

Sunday is profiled on the APIs.io network. Tagged areas include Company, Lawn Care, Consumer, Subscription, and E-Commerce.

Sunday’s developer surface includes engineering blog, support, pricing, 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/sunday: open an issue to ask a question, or submit a pull request to add artifacts.
