## 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-substitution-guide-f59360bd
```

Example prompt: I don't have heavy cream for my carbonara — what can I substitute for it, and what's the exact ratio I should use so the dish still comes out right?

## When to prefer this

Use this endpoint when a home cook or recipe agent needs to handle a missing ingredient at cook time, accommodate dietary restrictions, or adapt a recipe — especially when exact substitution ratios and quality notes matter more than a generic swap suggestion.

## Known failure modes

- Ingredient not recognized — returns error or empty results if the ingredient name is misspelled or too obscure
- No known substitutes exist for the requested ingredient — returns empty substitute list
- Missing required ingredient parameter — returns 400 bad request
- Payment not processed — returns 402 Payment Required if x402 payment is missing or insufficient

## 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

Returns a list of viable ingredient substitutes with exact ratios (e.g. '3/4 cup milk + 1/3 cup butter per 1 cup heavy cream'), plus honest notes on how closely each substitute replicates the original ingredient's flavor, texture, and behavior in cooking.
