description: Calysta, Inc. is a cellular agriculture company founded in 2012 and headquartered in San Mateo, California, with
  operations in Memphis, Tennessee (NouriTech), Wilton/Teesside in the United Kingdom (Calysta UK Ltd.) and Singapore (Calysta
  Asia Pte Ltd.). It produces protein ingredients through a patented gas-fermentation platform in which a naturally-occurring
  microorganism converts carbon and energy into a non-GMO single-cell protein, using no arable land and no plant or animal
  inputs. Its product family includes FeedKind for aquaculture and livestock, FeedKind Pet, FeedKind Net Zero and Positive
  Protein for human food ingredients; FeedKind Aqua is sold globally through Calysseo, a 50/50 joint venture with Adisseo
  whose first production plant in China manufactures thousands of tonnes per year. Calysta sells physical protein ingredients
  to feed and food manufacturers — its fermentation platform is industrial process technology, not commercial software — and
  it publishes no public API, developer portal, SDK, or machine-readable specification.

  detail: Calysta sells single-cell protein ingredients (FeedKind, Positive Protein) manufactured by an industrial gas-fermentation
    process; its complete 33-page WordPress sitemap has no developer, docs or API page, and the only machine-readable surface
    on the host is the stock WordPress REST API at /wp-json/ whose 273 routes are all core or third-party plugin namespaces
    with no first-party Calysta namespace.

  x-evidence-note: The two HTTP 200 rows are the soft-404 control pair — calysta.com answers every unknown path with the identical
    148,659-byte homepage, so the 200 on /.well-known/agent-card.json matches the random control byte-for-byte and is not
    an agent card. No A2A artifact was written.
