## 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 friday-seller-tools-shipping-template-cost-estimate-1323d567 -d '<json body>'
```

Example prompt: Can you estimate the shipping template cost for a 2 lb product shipping to the continental US that I'm listing on Amazon — I need to know the cost before I set up my shipping template.

## When to prefer this

Use this endpoint when an Amazon, Walmart, Shopify, or eBay seller needs a quick, low-cost ($0.25) estimate of shipping template costs before creating or uploading a product listing. Prefer this over manual carrier rate lookups when the goal is marketplace-specific shipping template pricing rather than live carrier quotes.

## Known failure modes

- Missing required shipping parameters returns a 400 error
- Invalid marketplace platform identifier causes validation failure
- Oversized or out-of-range weight/dimension inputs may be rejected
- Payment not included or insufficient USDC triggers x402 payment required response
- Service downtime on Railway hosting returns 5xx errors

## How this service works

Instant, low-cost Amazon, Walmart, Shopify, and eBay listing, upload-preparation, advertising, and image-brief deliverables.

## Output

Returns a job_id and status (e.g. 'queued'), indicating the cost estimate request has been accepted and is being processed. The agent should poll or await the job result to retrieve the computed shipping template cost estimate.
