GET /api/wirecutter/search

live

Search the persisted Wirecutter recommendation database by product type, pick name, review title, category, and model tokens. Search is lexical today; pass concise, spelling-corrected product/category nouns instead of vague natural-language intent.

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

curl -si -X GET 'https://stableproduct.dev/api/wirecutter/search' -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.
