## 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 mealpulse-ingredient-substitute-finder-2d45f2f8
```

Example prompt: I'm out of buttermilk and I also need a dairy-free option — what can I substitute and in what ratio? The reason is I'm out of it and also trying to go dairy-free.

## When to prefer this

Use this endpoint when a user needs to substitute a specific ingredient due to being out of it, a food allergy, or a dietary restriction (e.g. vegan, keto, gluten-free), and requires precise conversion ratios rather than vague suggestions. Prefer this over a general recipe API when the user's core need is a like-for-like ingredient swap with honest accuracy notes.

## Known failure modes

- Unknown or misspelled ingredient returns no results or an error
- Unsupported reason enum value causes a validation error
- Exotic or hyper-regional ingredients may return limited substitution options
- Network or payment failure returns a 402 or 5xx error

## How this service works

Ingredient substitute finder / what can I use instead of X / cooking swap calculator. Takes an ingredient and the reason (out of it, allergy, dietary) and returns replacement options with exact conversion ratios and honest notes on how close each substitute comes. Worldwide.

## Output

A list of substitute ingredients for the queried ingredient, each with an exact conversion ratio (e.g. '1 cup buttermilk = 1 cup oat milk + 1 tbsp vinegar') and an honest note on how closely each substitute approximates the original in flavor, texture, and cooking performance.
