  • kimchi_premiumFree

    Kimchi premium on two bases: premium_official_pct (official USD/KRW rate — the quoted figure) and premium_usdt_pct (Upbit KRW/USDT rate — a gross spot-price comparison using KRW/USDT conversion, before spreads, fees, liquidity and transfer constraints).

Costs $0.08 in USDC per call, settled via x402.

  • kimchi_premium_statsFree

    Where the current kimchi premium sits inside its own recent distribution: percentile, mean, stdev, z-score, min/max/median, and a plain-language read. Answers 'is this premium unusual right now?' in one call. Built from the recorded archive; inspect actual dates and freshness with the free coverage endpoint. Params: ?symbol=BTC &window=1h|6h|24h|7d|30d|90d &basis=usdt|official. Costs $0.12 in USDC per call, settled via x402.

  • korea_market_snapshotFree

  • news_headlinesFree

    Latest Korean headlines from Yonhap, Maeil Business and Hankyung, deduplicated and newest-first. Titles stay in Korean — use /api/news/headlines/en for English. Optional ?category=top|economy|tech|politics and ?limit=30 (max 100). Costs $0.01 in USDC per call, settled via x402.

  • news_headlines_enFree

    Latest Korean headlines with English translations attached (title_en), from Yonhap, Maeil Business and Hankyung — deduplicated, newest first.

  • research_consensus_tickerFree

    Analyst consensus for one KRX ticker, built from the archived research history: mean/median/min/max target price across brokerages, the spread between them, the rating distribution, and a revision log of every target-price and rating change each house has made. Consensus uses each house's latest view, so a weekly publisher does not outvote a quarterly one. Params: ?window=30d|90d|180d|365d (default 90d). Costs $0.12 in USDC per call, settled via x402.

  • research_latestFree

    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.

What the publisher says

From the K-Data — Korean Sell-Side Research & Market Data repository's README, as published. We do not edit it. Read it on GitHub

k-data-mcp

MCP server for Korean equity research and market data, metered per call in USDC over x402. Start it without a wallet to inspect the catalog and run free, date-stamped previews; add a dedicated wallet only when you want paid calls.

Try before funding a wallet

Run npx k-data-mcp with no environment variables to use these free tools:

  • list_endpoints — paid catalog and prices.
  • previewresearchcoverage — real per-ticker report/brokerage counts and archive date ranges.
  • preview_research — a single ticker's actual archive depth; this does not disclose report content.
  • previewkimchipremium — live BTC-only dual-basis sample.

Set KDATAPRIVATEKEY and KDATAMAXSPEND_USD only when you are ready to enable paid tools.

What you get

  • Kimchi premium on a tradeable basis. Everyone quotes the premium against the official USD/KRW rate, but Korean capital controls mean the KRW exit leg actually goes through USDT — so that number is not something you can trade on. This returns both, and they routinely disagree in sign: official can read −0.27% while the realizable basis is +0.19%.
  • Premium history and percentile context. A continuously recorded archive answers "is this premium unusual right now?" — percentile, mean, stdev, z-score over 1h–90d. No free source publishes this, and it cannot be reconstructed after the fact.
  • Korean headlines translated to English, from Yonhap, Maeil Business and Hankyung. Korean myriad units (억 / 조) are expanded deterministically before translation, so "989억달러" comes back as $98.9 billion rather than the 10×-off answer language models produce unaided.
  • Korean sell-side research as structured data. Target prices, ratings, brokerage and analyst per KRX ticker, each with an English summary, plus the consensus and revision history built from them — who raised, who cut, and how far apart the houses actually are. Only the facts of each report are sold, in our own words, with a link back to the publisher; the report PDF stays with the brokerage that wrote it. The listing source shows a rolling recent window only, so this series cannot be reconstructed after the fact either.
  • Upbit KRW quotes and market summaries, USD/KRW.

}

Wallet setup

Each tool call spends real USDC, so the server will not start without a key and a budget.

  1. Create a dedicated wallet — not your main one. The key sits in a config file and every call spends from it.
  2. Fund it with the USDC you're willing to spend on Base. No ETH needed: x402 settles with an off-chain EIP-3009 signature and the facilitator pays the gas.
  3. Set KDATAMAXSPENDUSD. The server refuses any call that would push cumulative spend past it.

Tools

listendpoints is free** — call it first to see current prices and decide what's worth buying.
