L-Nutra

L-Nutra, Inc. is a Los Angeles based nutri-technology company founded on the fasting-mimicking diet (FMD) research of Dr. Valter Longo at the USC Longevity Institute. It develops and sells clinically studied nutrition programs — the ProLon 5-Day Fasting Mimicking Diet, Fast Bar and related longevity nutrition products — direct to consumers, to healthcare providers, and through an employer and health-plan channel. L-Nutra is not a developer-platform company and publishes no developer portal, OpenAPI description or API reference of its own. Its machine-readable surface is the agentic-commerce layer of its three Shopify storefronts (prolonlife.com, l-nutrahealth.com and l-nutraprofessional.com): each serves an llms.txt / agents.md agent instruction document, a Universal Commerce Protocol (UCP) discovery profile at /.well-known/ucp, an anonymous MCP endpoint at /api/ucp/mcp exposing thirteen catalog, cart, checkout and order tools, a Shopify Storefront MCP endpoint at /api/mcp, and Shopify customer-account OpenID Connect discovery documents.

L-Nutra publishes 3 APIs on the APIs.io network. Tagged areas include Company, Nutrition, Health, Longevity, and Consumer Products.

L-Nutra’s developer surface includes documentation, support, pricing, signup flow, authentication, and 18 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/l-nutra: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
