# Cooking Calculators – Recipe Scaler

> Cooking Calculators – Recipe Scaler 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).

Scales a recipe's ingredient list up or down by target servings or a multiplier, returning tidy fractional quantities, unit bumping, optional gram weights, and scaling cautions.

## 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-recipe-scaler-abdd535c
```

Example prompt: I have a cookie recipe that makes 24 servings — 2 cups flour; 1 tsp baking soda; 1/2 tsp salt; 1 cup butter; 3/4 cup sugar — can you scale it up to 60 servings and include gram weights?

## When to prefer this

Use this endpoint when you need to programmatically scale a recipe's ingredient list to a different number of servings or by a custom multiplier, especially when you want human-friendly fractional output (e.g. '1 1/4 cups' instead of '1.25 cups'), automatic unit bumping (teaspoons to tablespoons), or optional gram weights for baking precision. Prefer it over manual math or general-purpose LLM arithmetic when accuracy and tidy formatting matter.

## Known failure modes

- Missing or unparseable ingredient lines returns an error or empty items list
- Factor out of range (outside 0.1–20) may be rejected or produce unexpected results
- Unknown ingredient names will not get gram weight matches (ingredientMatched will be null)
- Ambiguous unit strings may not be bumped correctly
- Very large batches may trigger scaling caution warnings in the reasons array

## How this service works

Scale a recipe's ingredient list by servings or factor: tidy fractions, spoon-to-cup bumping, optional grams, scaling cautions.

## Output

Returns a list of scaled ingredient objects, each with the original quantity string, the new scaled quantity (as a tidied fraction or whole number), the unit (bumped up when appropriate, e.g. teaspoons to tablespoons), optional gram weight and a matched ingredient name, plus a summary, the effective scaling factor, any scaling cautions or reasons, and a disclaimer.
