Features

✓

Up to 100 3P offers per call

A single /v1/amazon/product-offers call returns up to 100 third-party seller offers for one ASIN — controlled by the limit parameter — giving you the deepest view of who's selling a product and at what price.

✓

Price, condition, and seller byline per offer

Each offer carries its own price, condition (new/used/renewed), and seller byline, so you can compare every competing listing for the same ASIN line by line.

✓

Buy-box price and availability

Returns the buy-box data and product_price for the featured offer, the figure repricers and arbitrage tools watch most closely.

✓

Filter by condition (new/used/renewed)

Restrict the offer set to new, used, or renewed listings so condition-specific repricing and arbitrage screens only see relevant competition.

✓

Highest-fidelity Amazon pricing source

By exposing every 3P offer rather than just the headline price, this is the most precise pricing view in the suite — built for buy-box monitoring and repricer triggers.

Use cases

Repricing

Monitor competing 3P sellers' prices to trigger your own repricer.

Buy-Box Monitoring

Alert when buy-box ownership or price changes on your listings.

Arbitrage

Find retail-arbitrage opportunities across conditions.

The Amazon Offers API for multi-seller pricing

The YepAPI Amazon Product Offers API exposes every third-party offer behind a single ASIN. Send the ASIN to /v1/amazon/product-offers and get back up to 100 offers — each with its own price, condition, and seller byline — plus the buy-box and product_num_offers, all at $0.02 per call. It is the highest-fidelity pricing view in the Amazon suite.

This is the endpoint for repricing and buy-box work, and it answers a different question than Product Details. Product Details tells you about the item; Offers tells you everyone who is selling it and for how much. That multi-seller spread is what powers repricers, buy-box alerts, and retail-arbitrage screening across conditions.

What is an Amazon Offers API?

An Amazon Offers API returns the full set of competing offers for a single product. Where most lookups give you one headline price, the offers endpoint enumerates up to 100 third-party listings for an ASIN — each with price, condition, seller byline, and delivery — plus the buy-box and total offer count. It exists because the buy box and the offer spread, not the list price, are what actually drive marketplace pricing decisions, and tracking that many seller listings by hand or by scraper is brittle and slow.

Build your own repricer

Poll /v1/amazon/product-offers for your ASINs, read the buy-box price and the competing 3P offers, and trigger your own repricing logic when a rival undercuts you or the buy box changes hands. The limit parameter (up to 100) controls offer depth, and condition filters keep new/used/renewed comparisons clean. Combine it with the Amazon Seller API to vet each competing seller's rating before reacting — both run on one YepAPI key alongside SEO, SERP, and AI endpoints.

Amazon Offers API pricing — $0.02 per call

Offers costs $0.02 per call, returning up to 100 third-party offers per ASIN. The higher rate reflects the depth: you're pulling the entire seller spread, not a single price. With no quotas or monthly minimums, monitoring a 500-ASIN repricing portfolio once is a flat $10. Rainforest API and Oxylabs meter differently per request and per month; YepAPI's per-call model keeps high-frequency buy-box polling predictable.

Buy-box monitoring and arbitrage

The reason to reach for Offers over Product Details is precision on competition. By exposing every 3P offer with its condition and seller, you can detect buy-box ownership changes the moment they happen, spot retail-arbitrage gaps between conditions, and feed accurate competitor prices into automated repricing. It is the endpoint that turns "what does this cost" into "who is winning the buy box and how do I beat them."
