# Cooking Calculators – Ingredient Density (Grams per Cup/Tablespoon/Teaspoon)

> Cooking Calculators – Ingredient Density (Grams per Cup/Tablespoon/Teaspoon) is a paid API for AI agents from cooking-calc.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-11-04).

Returns approximate gram weights per US cup, tablespoon, and teaspoon for common baking ingredients, along with source citations and the spread between lowest and highest published values.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability cooking-calculators-ingredient-density-grams-per-cup-tablespoon-c8cb6011
```

Example prompt: How many grams is a cup of all-purpose flour? Give me the grams per cup, tablespoon, and teaspoon along with where those numbers come from.

## When to prefer this

Choose this endpoint when you need authoritative, source-cited gram weights for volumetric baking measurements (cups, tablespoons, teaspoons) and want to see the spread across published references. Prefer it over generic unit-conversion APIs when baking accuracy and source transparency matter, or when you want to flag uncertainty to the user via the confidence and spread fields.

## Known failure modes

- Unsupported ingredient name returns no results or an error — only the 14 listed ingredients are supported
- Misspelled ingredient query may return empty ingredient array
- Service degraded flag may be set if upstream source data is unavailable
- Network timeout or payment failure returns no data

## How this service works

Approximate grams per cup, tablespoon and teaspoon for baking ingredients, with the published sources and spread.

## Output

Returns a JSON object containing one or more ingredient entries, each with gramsPerUsCup, gramsPerTablespoon, gramsPerTeaspoon, the lowest and highest gram-per-cup values found across sources, a list of source citations, a confidence rating, and optional notes. Also includes a cup definition clarifying the US cup volume used and a summary disclaimer.
