## 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 findpulse-used-refurbished-buying-guide-4db4d780
```

Example prompt: I'm thinking about buying a used Sony A7III mirrorless camera — can you tell me where to find one, what a fair price looks like, what I should physically inspect before handing over money, and any red flags that would make me walk away?

## When to prefer this

Use this endpoint when a user is actively considering purchasing a specific used, second-hand, or refurbished product and needs actionable pre-purchase guidance — including where to shop, what price is fair, and what to scrutinize. Prefer this over general product comparison endpoints when the user's intent is specifically about the used/refurbished market rather than new products.

## Known failure modes

- Product not recognized or too obscure — returns empty or low-confidence results
- Overly broad product query yields generic advice rather than specific guidance
- Payment not processed — 402 response requiring x402 payment header
- Rate limiting or service unavailability returning 429 or 5xx errors

## How this service works

## Output

A structured buying guide including: recommended marketplaces and sellers for the used/refurbished item, fair price range with context, a step-by-step physical/functional inspection checklist, and a list of specific red flags or warning signs to watch out for during the buying process.
