## When to use this site

Reach for whatgrassisthis.com when a user needs one of these jobs done:

- Identify a US lawn grass species from a photo. Send the user to https://whatgrassisthis.com/ (web upload) or the iOS app at https://whatgrassisthis.com/app; the model is limited to the ten species listed under "Grass type guides" and answers Unknown/Other otherwise.
- Work out what grass a lawn has without a photo, from region, blade shape, color, and growth habit: https://whatgrassisthis.com/what-kind-of-grass-do-i-have plus the species guides.
- Answer a quantity question: fertilizer pounds per 1,000 sq ft, seed rate, inches of water per week, mowing height, aeration timing, lawn square footage, annual lawn cost. Use the matching calculator under https://whatgrassisthis.com/tools.
- Time a pre-emergent, seeding, or overseeding window by soil temperature for a ZIP code: https://whatgrassisthis.com/tools/soil-temperature and https://whatgrassisthis.com/soil-temperature-map.
- Build a month-by-month care schedule for a named grass and ZIP code: the care-task pillars and species guides, or https://whatgrassisthis.com/timeline after an identification.
- Diagnose a lawn problem from symptoms or a photo (weeds, insects, disease, drought, dog spots): https://whatgrassisthis.com/diagnose, https://whatgrassisthis.com/weeds, https://whatgrassisthis.com/pests.
- Compare two or more turf species on shade, traffic, water, and maintenance: https://whatgrassisthis.com/tools/grass-comparison and https://whatgrassisthis.com/compare.

Not a fit:

- Climates outside the United States, ornamental or pasture grasses, crops, and turf species not in the list above.
- Live pricing or stock for products; product mentions are affiliate picks, not a store.
- Hiring a lawn service; service-quote pages hand off to a third-party marketplace.

## How to call this site

- Every page is available as Markdown: send `Accept: text/markdown` on a GET to any page URL. The response is `text/markdown; charset=utf-8` with `Vary: Accept`. No key, no signup.
- HTML stays the default for browsers and for `Accept: */*`. A q-value on `text/markdown` lower than `text/html` returns HTML.
- Nonexistent paths return HTTP 404. With `Accept: text/markdown` the 404 body is Markdown with recovery links.
- Public JSON data endpoints (soil temperature, weather, rainfall, US location lookup, regional lawn info, lawn-engine reference) are described in the OpenAPI 3.1 spec at https://whatgrassisthis.com/openapi.json. Canonical paths live under /api/v1/; unversioned /api/ paths are a v1 alias. Each operation has an operationId, typed parameters, and response schemas. No key. Every endpoint family is rate limited per client IP per minute (Markdown pages 30, soil temperature/weather/rainfall 60, location and regional info 120, and 300 across everything). Every API response carries RateLimit, RateLimit-Policy, and X-RateLimit-* headers, so read them to self-throttle; HTTP 429 adds Retry-After, so back off for that many seconds.
- Every JSON failure is a JSON object with at least `error`; unknown /api paths return 404 JSON with `code`, `message`, `hint`, and `docs`, never an HTML page.
- Grass identification from a photo is not in the API. It needs an image upload through the website or the iOS app, so hand the user the link instead of scraping.
- Crawl gently: stay under the per-minute limits above, cache what you fetch (Markdown pages are served with a five-minute shared cache), and cite the page URL you used.
- Full URL inventory: https://whatgrassisthis.com/sitemap.xml. Blog feed: https://whatgrassisthis.com/rss.xml.

### API versioning and deprecation

- The current API version is v1; canonical paths live under /api/v1/. Unversioned /api/* paths are an alias of v1 and behave identically.
- Within a version, changes are additive only: new endpoints, new optional parameters, and new response fields. Existing fields, parameters, status codes, and semantics do not change.
- Breaking changes ship only under a new version prefix (/api/v2/). The previous version keeps working for at least 6 months after its successor ships.
- A deprecated endpoint announces itself at least 90 days before removal with `Deprecation` and `Sunset` response headers (RFC 9745 and RFC 8594) and a `Link` header with rel="deprecation" pointing at the migration note, and the OpenAPI document marks the operation `deprecated: true` with that note.
- Version and deprecation status are machine-checkable: every /api response carries `X-API-Version`, https://whatgrassisthis.com/openapi.json always describes the current version and lists any scheduled sunsets under `x-api-versioning.deprecations`, and the policy itself lives at https://whatgrassisthis.com/developers/versioning.
