## 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-price-per-ml-36947e1f
```

Example prompt: What's the price per ml for Dior Sauvage EDT — I want to see the breakdown across all available bottle sizes so I can figure out which one gives the best value.

## When to prefer this

Use this endpoint when you need to calculate or compare the per-milliliter cost efficiency of a specific named fragrance across bottle sizes. Ideal for dupe-hunters justifying alternatives, collectors evaluating purchase sizes, or blind buyers optimizing budget. Prefer this over general retail search when you want a structured cost-per-ml metric rather than raw listing prices.

## Known failure modes

- Fragrance not found in database — returns empty or error response
- Ambiguous fragrance name with multiple flankers may return unexpected variant
- Price data may be stale if market prices have shifted
- Only approximate retail prices, not current sale or resale prices
- Payment signature missing or invalid — returns 402 Payment Required

## How this service works

Fragrance intelligence for perfume collectors, dupe-hunters, and blind-buyers. All endpoints require x402 payment (USDC on Base mainnet, or Solana USDC-SPL) via the PAYMENT-SIGNATURE header.

## Output

A JSON object containing the fragrance name and an array of size options, each with the bottle volume in ml, the approximate retail price in USD, and the calculated price-per-ml in USD. Allows direct value comparison across sizes.
