GET /agent/v1/stock

live

Live Amazon offer and inventory data for up to 10 ASINs: every active offer with seller, price, shipping and condition, which one holds the buy box, and optionally the real purchasable stock quantity. Built for repricing, buy-box monitoring and stock-out alerting across 20 marketplaces.

Verdict: live. The unpaid GET reached a valid 402 (confirmed by the re-probe of 2026-10-01).

Try it (unpaid: shows the 402)

curl -si -X GET 'https://agent.apiguru.app/agent/v1/stock' -H 'accept: application/json'

The catalog declares GET. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
