## 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 arbipulse-flip-check-resale-arbitrage-verdict-0bb2dd04
```

Example prompt: Check if a sealed Lego 75192 Millennium Falcon I can buy for $550 is worth flipping — give me the verdict, expected sale price, profit, and ROI.

## When to prefer this

Use this endpoint when you need a fast, quantified verdict on whether a specific physical item is worth buying for resale, with profit and ROI estimates against median comparable sales — ideal for retail arbitrage bots, deal-scanning agents, or reseller assistants evaluating collectibles, toys, sneakers, or electronics. Prefer this over manual comp lookups or generalist price APIs when you want a structured THIN/GOOD verdict with P&L math already computed.

## Known failure modes

- Unknown or ambiguous item name returns low-confidence or empty comp data
- Very niche items with no comparable sales data may return null projections
- Incorrect buy price input yields misleading ROI figures
- Rate limiting or payment failure returns 402 error requiring USDC payment
- Item with no liquid resale market may return THIN verdict with zero comps

## How this service works

Retail resale arbitrage check — "if I buy this at this price, what do I clear reselling it?" Live eBay ask comps (each linked to its listing; web-grounded fallback), fee math for eBay/Amazon/StockX/Poshmark/Mercari, profit + ROI at low/median/high comps, best-venue table, FLIP / THIN / PASS verdict. Returns INSUFFICIENT_EVIDENCE rather than an invented price.

## Output

Returns a JSON object with the item name, a verdict label (e.g. THIN, GOOD), the buy price input, and at-median-comp projections including expected profit in dollars and ROI percentage, based on comparable market sales data.
