TDQS

A3.9/5.0

Scored across 16 tools

Disambiguation4/5

Most tools have clearly distinct purposes (live ticker vs. history vs. distribution stats vs. snapshot; Korean vs. English news; per-ticker vs. consensus vs. latest research). The main overlaps are the free preview_* endpoints duplicating paid counterparts and korea_market_snapshot bundling kimchi_premium + crypto_krw_markets + fx_usdkrw, but descriptions clearly flag these relationships.

Naming Consistency5/5

All tools use consistent snake_case with predictable domain prefixes (crypto_, kimchi_, news_, research_, preview_, fx_). Names are readable and follow a stable noun/verb-noun convention throughout.

Tool Count4/5

16 tools is slightly above the typical sweet spot but justified by the server spanning two product lines (crypto/FX market data and equity research) plus a deliberate free-preview tier. Each tool maps to a distinct endpoint; no filler.

Completeness4/5

Covers live quotes, history, stats, snapshots, bilingual news, and per-ticker/consensus/latest research, which is solid lifecycle coverage for the stated purpose. Minor gaps exist (e.g., no equity index/OHLC history, no search by brokerage/analyst, no historical FX series), but core workflows are complete.

Each page is a separate paid request. Continue while has_more is true using next_before. Inspect actual archive depth and freshness through /api/preview/premium-coverage before buying. Costs $0.08 in USDC per call, settled via x402.

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.

Inputs: basis, symbol, window.

Inputs: limit, category.

news_headlines_enAInspect

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

Costs $0.05 in USDC per call, settled via x402.

Inputs: limit, category.

Free, date-stamped archive-depth check for one 6-digit KRX ticker. Shows report and brokerage counts, not report content or consensus.

Inputs: ticker (required).

preview_research_coverageAInspect

Free, date-stamped KRX research coverage. Lists the most-covered tickers with report count, brokerage count, and archive date range; it does not reveal report content.

Inputs: limit.

Every archived Korean brokerage report for one KRX ticker, newest first: target price, rating, brokerage, analyst, the Korean title with its English translation, and a one-line English summary. Params: ?limit=20 (max 50). Costs $0.05 in USDC per call, settled via x402.

Inputs: ticker (required), limit.

research_consensus_tickerAInspect

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.

Inputs: ticker (required), window.

research_latestAInspect

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.
