# Customer reviews for a single ASIN

`GET /v2/product-reviews`

## Request

- Base URL: `https://dash.apiguru.app/api/v1`
- URL: `https://dash.apiguru.app/api/v1/v2/product-reviews`
- Auth: one of:
  - API key in header `X-API-KEY`
  - API key in query parameter `api_key`
  - none

Use for what customers say about one product. Not for its full review history (Amazon serves full and star-filtered review lists only to signed-in accounts) or for seller feedback (seller_reviews). Returns the overall rating, rating count, review_histogram (percent of all ratings per star), Amazon's 'customers say' AI summary where that marketplace shows one, and the reviews on the product page (typically up to 8 from this marketplace and 5 from other countries), each with rating, review_date, review_country, from_this_marketplace, verified flag and helpful_votes; from_rating/to_rating keep a star window.

**Price:** $0.003 per call

**Notes:** Same 404-billed / 503-not-billed semantics as product_details. No paging or sort: the reviews are those on the product page; review_coverage says how many and from where. from_rating/to_rating filter them. review_histogram (here and on product_details) gives the share of every rating. customers_say is null where Amazon shows no summary (several marketplaces never do); customers_say_note then says so.

## Query parameters

- `asin` string, required
- `geo` 'US' | 'CA' | 'DE' | 'MX' | 'UK' | 'FR' | 'IT' | 'ES' | 'AU' | 'BR' | 'IN' | 'JP' | 'NL' | 'AE' | 'PL' | 'SA' | 'SG' | 'SE' | 'TR' | 'BE' | 'IE' | 'ZA' | 'EG'
- `from_rating` integer
- `to_rating` integer

## Response `200`

Success.

- object

## Other responses

- `400`: Bad input (bad ASIN format, unknown geo, missing required param), or a page past the last one Amazon serves for a list (`code: page_out_of_range`, with `reachable_pages`). On agent.apiguru.app an `api_key` in the URL is refused the same way (`code: api_key_in_query`): send it as the X-API-KEY header. NOT billed.
- `401`: Missing or invalid API key on the keyed path.
- `402`: Payment required. On the agent path this carries a PAYMENT-REQUIRED challenge (over MCP: an x402 PaymentRequired tool result, payable in-band via _meta["x402/payment"]). On the keyed path it means the account balance is exhausted.
- `403`: Account disabled, or no active subscription plan.
- `404`: The ASIN genuinely does not exist on that marketplace. BILLED - the lookup was performed and the bad input was the caller's. Retrying will not help; try a different geo.
- `413`: Too many items in a batch request.
- `429`: Per-second rate limit exceeded for the plan (`code: rate_limited`, `Retry-After: 1`). NOT billed. Back off and retry.
- `500`: Internal error. NOT billed.
- `502`: Bad gateway. NOT billed. Same class as 503: retry with backoff.
- `503`: Temporary failure on our side (`code: upstream_unavailable`). NOT billed. Safe and correct to retry.
- `504`: Gateway timeout: no answer within 55 s, so agent.apiguru.app stopped the request before it was billed (`code: deadline_exceeded`). NOT billed. Retry once; a batch with fewer items answers sooner.
- `timeout`: No response before your own client's deadline. A keyless call without a payment is never billed. On an API key, or with an x402 payment attached, the request may still complete after your client gave up, and is then billed like any answered call. Some marketplaces answer more slowly than others; allow 60s rather than retrying early (agent.apiguru.app answers a 504 itself at 55 s).
