## 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 scentpulse-fragrance-reformulation-checker-07d83a4c
```

Example prompt: Can you check if Creed Aventus has been reformulated since its original release? I have a batch code of 21P01 — does that put my bottle before or after the known formula changes, and what IFRA-driven ingredient differences should I know about?

## When to prefer this

Choose this endpoint when a user needs to verify whether a specific fragrance has changed formulation over time, especially when a batch code is available for precise production-year mapping. Prefer this over generic fragrance note lookups when the core question is about formula authenticity, vintage vs current quality differences, or IFRA-compliance-driven ingredient substitutions. Ideal for pre-purchase due diligence on secondary market bottles or collector authentication.

## Known failure modes

- Fragrance not found in database — returns null or not-found status for obscure niche or indie releases
- Batch code not recognized — production year cannot be derived, reformulation timeline still returned without batch mapping
- Reformulation history uncertain — community documentation sparse, returns low-confidence flag
- IFRA amendment data incomplete for very old reformulations pre-dating systematic tracking
- Ambiguous fragrance name (e.g. multiple flankers or regional variants) — may require additional disambiguation parameter

## How this service works

Fragrance reformulation checker — has this scent changed since its original release? IFRA-amendment-driven ingredient changes, community-documented vintage-vs-current differences, and how a batch-code-derived production year lines up against known reformulation events.

## Output

Returns a reformulation status (reformulated / unchanged / uncertain), a timeline of known reformulation events with approximate dates, IFRA amendment references that drove ingredient changes, community-documented differences between vintage and current versions, and — if a batch code is provided — the derived production year mapped against those reformulation events to indicate which formula version the bottle likely contains.
