GET /api/research/latest

live

Latest Korean brokerage equity research across all covered companies, newest first — company and KRX ticker, target price, rating, brokerage, analyst, and a one-line English summary of each report. Facts and summaries only; the report PDF stays with its publisher and source_url links back to it. Optional ?limit=20 (max 50).

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

curl -si -X GET 'https://k-data-x402-production.theblack1022.workers.dev/api/research/latest' -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.
