Kisnet Ytm

KIS-NET YTM

Import YtmClient and the operation-specific validation helpers from @sjunepark/ytm. The package is a Rust-backed Node SDK and does not declare or distribute a CLI. Publication of the rewritten package is not yet authorized.

• For the latest N observation dates, use history({ count: N, endDate: "YYYY-MM-DD" }), with optional inclusive startDate. Count is 1–2000; the exact backward scan stops within 2000 calendar days. Do not combine count with a date list or previous-available fallback. A shortfall raises insufficient_history.
• A numeric yield anywhere qualifies a date; missing cells may remain. Report requestedDates.length as the selected date count and preserve countSelection. availableCount counts date/category pairs, not dates.
• Dates accept YYYY-MM-DD, YYYY.MM.DD, or YYYYMMDD.
• Kind accepts a source code or Korean label. The canonical catalog includes 80 회사채(사모), distinct from 70 회사채(무보증).
• Exact-date lookup is the default. Use previous-available only when the caller authorizes walking backward through calendar dates.
• Retry fallback only after confirmed unavailable data. Transport, protocol, and source-format failures stop immediately.
• Failures expose structured recovery metadata; inspect it before retrying.
• Report requested and resolved dates, kind, tenors, and rows by 적용대상채권. Source - or empty yields become null while raw text remains available.
