Reference amounts and Daily Values, quoted from regulation.
Connect reference_amounts to your agentWhat it answers
The reference amounts customarily consumed and the Daily Value tables, quoted verbatim from the Code of Federal Regulations and cited to the section and the date the text was read. Amounts stay as the regulation words them — including household measures and conditional forms — because parsing one to a number discards the half of the rule that decides how it applies. A Daily Value is a labelling reference, not a Dietary Reference Intake; citature holds no licensed source for the latter and does not estimate whether anyone meets a nutrient requirement.
Ask it things like
- What is the reference amount for breakfast cereals?
- What Daily Value is used for sodium on a Nutrition Facts panel?
- How is serving size determined for a single-serving container?
What comes back
A receipt, and the same envelope on every tool — so a caller writes against one contract whichever one they call. The citations carry two clocks that are never collapsed: citature's retrieved_at and the source's own as_of, plus the record's own published_at and record_version where the source publishes them.
Answer
citature — reference_amounts receipt
- answer
- The rows themselves, typed per tool. Amounts carry their unit and their basis, because a figure per serving and one per 100 g are not comparable.
- citations
- The record behind the answer: a re-runnable upstream URL, citature's retrieval clock, the release's own currency date, and the record's own version.
- coverage
- What this answer does not reach, and where the record is silent rather than negative.
- guardrails
- The standing caveats, shipped in the answer itself rather than only on a page an agent never loads.
- matches
- Every join the answer used, named by method and confidence. A name match is reported as a name match, never as an identity.
- schema_version
- The conformed schema the answer was produced against, so a caller can pin it.

Connect reference_amounts to your agentguardrails & coverage
- Research over public records and product labels — not medical, nutritional, or safety advice.
- citature reports what the record says. It never renders a verdict, a pass/fail, a diagnosis, or a recommendation, and is not a substitute for a clinician.
- Answers are product-, substance- or population-level only — foods, supplements, labels, substances, enforcement actions, and dietary intake as a weighted survey estimate. No answer returns or describes an individual person, and citature links no record to individually identifiable data.
- A record that does not declare something is not a record declaring its absence. citature reports what a record states; it cannot report what a product does not contain, or what a population did not consume.
- A Daily Value is a labelling reference from federal regulation, not a Dietary Reference Intake. citature carries no licensed source for Dietary Reference Intakes and does not estimate whether anyone meets a nutrient requirement.
- Coverage reflects the records citature has ingested, not the full upstream history. Each dataset advances when its source publishes a release.
- Every answer states its own coverage caveats in the receipt's `coverage` field, alongside these standing guardrails.
