## 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 vortex-delivery-feasibility-check-256c3bfc -d '<json body>'
```

Example prompt: Before I place an order from that new Gymshark store for my customer in Canada, can you check whether they actually ship there and accept standard credit cards?

## When to prefer this

Choose this endpoint when an agent needs to gate a purchase decision on delivery feasibility before committing to checkout at an unfamiliar storefront. It is especially valuable in dropshipping pipelines, cross-border shopping agents, or marketplace bots where the seller's shipping coverage is unknown. Prefer it over manually scraping store pages when you need a structured reaches/cannot_reach/unknown verdict with reasons rather than raw HTML.

## Known failure modes

- Store does not publicly expose shipping zone data, returning 'unknown' verdict
- Storefront is geo-blocked or rate-limits crawling, preventing zone retrieval
- Insufficient prepaid credit balance results in payment failure before check executes
- Store URL is invalid or unreachable, causing an error response
- Shipping policy page is dynamically rendered and cannot be parsed reliably

## How this service works

Before buying from a store you have never used, ask whether it can even ship to your buyer. Most storefronts serve one country: Allbirds and Gymshark publish shipping to exactly one destination, Kith to 197. Vortex reads the shipping zones, currency and accepted cards each store publishes about itself and answers reaches, cannot_reach or unknown, with the reasons. US$1.00 of prepaid credit, about 500 checks, debited off-chain.

## Output

Returns a structured verdict of 'reaches', 'cannot_reach', or 'unknown' for the target store-to-destination pair, accompanied by the specific reasons drawn from the store's published shipping zones, supported currencies, and accepted card types. This lets an agent make a go/no-go decision before attempting a purchase.
