## 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 zinc-product-offers-api-f1d7ea1b -d '<json body>'
```

Example prompt: Can you check the current offers and pricing on Amazon for the product with ASIN B08N5WRWNW? I want to see all available sellers and their prices.

## When to prefer this

Choose this endpoint when you need structured, up-to-date offer and pricing data for a specific product on Amazon or Walmart by product ID (e.g. ASIN), especially in automated buying pipelines where you need to verify pricing before placing an order. Prefer this over scraping or generic web search when you need machine-readable, structured offer data with seller breakdowns and availability flags integrated into a commerce automation workflow.

## Known failure modes

- Invalid or non-existent product_id returns an error or empty offers list
- Unsupported retailer value (anything other than 'amazon' or 'walmart') returns a validation error
- Product not available in the retailer's catalog returns empty results
- Response age constraints (max_age, newer_than) may trigger a fresh fetch with higher latency
- Async mode returns immediately with processing status, requiring a follow-up poll for results
- Rate limiting or payment failure returns 402 or 429 error
