# Forest Commerce Buyability Check

## 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 forest-commerce-buyability-check-dfab5c5d -d '<json body>'
```

Example prompt: Before I try to buy it, can you check if this product URL is actually buyable right now — I want quantity 2 of the blue variant: https://www.example.com/product/12345?

## When to prefer this

Use this endpoint when you need a lightweight, read-only preflight check on whether a public product URL appears buyable before committing to a checkout flow. Prefer this over the cart-checkout endpoint when you want a fast signal without even attempting to build a cart. Best when you need to detect hard blockers (out-of-stock, unavailable variants) early in an automated purchasing workflow.

## Known failure modes

- URL is not a recognized marketplace product page — returns unknown or error status
- Item page requires authentication to view availability — blocker reported as unknown
- Network timeout or unreachable URL — error response
- Requested quantity exceeds provider limits (max 100) — validation error
- Dynamic or JavaScript-rendered pages may not expose stock signals — result may be inconclusive

## How this service works

Report whether a public item appears buyable with explicit blockers such as out-of-stock or unknown. This is a preflight only: it never signs in, buys, creates an order or guarantees checkout. Base mainnet USDC

## Output

Returns a buyability status indicating whether the public item appears purchasable, along with any explicit blockers detected (e.g. out-of-stock, quantity limits exceeded, unknown status). Does not guarantee successful checkout and never initiates a purchase or login.
