Output
Returns a list of offers for the specified product on the given retailer, including pricing, seller details, availability status, and condition information. Response may be returned synchronously or asynchronously (with status=processing) depending on the async flag.
Example use cases
Price check before automated purchase
“Before placing an order, look up all current Amazon offers for ASIN B07XJ8C8F5 — I want to see the lowest price available right now so I can decide whether to buy.”
Walmart stock availability monitor
“Check if product ID 565679903 is currently available on Walmart and what the current offer price is — I need to know if it's in stock before I automate a reorder.”
Multi-seller price comparison
“Pull all the seller offers for Amazon ASIN B09G9HD6PD so I can see which seller has the best price and shipping options before my buying agent places the order.”
Technical details
Endpoint
POSThttps://api.zinc.com/agent/products/offers?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
