Summary

토스증권 조회형 질문을 공식 Open API(OAuth2)로 우선 처리하고, 공식 credentials가 없으면 tossinvest-cli의 tossctl을 fallback으로 써서 계좌, 보유주식, 시세/종목/시장정보, 주문조회를 안전한 read-only 흐름으로 조회한다.

SKILL.md

Toss Securities

What this skill does

토스증권 조회 전용(read-only) 흐름을 실행한다. 두 경로가 있다.

  1. 공식 Open API (권장) — 토스증권 공식 Open API(https://openapi.tossinvest.com)를 OAuth 2.0 Client Credentials 토큰으로 호출.
  2. tossctl fallback — 공식 credentials가 없을 때 JungHoonGhae/tossinvest-cli 의 tossctl 을 사용.

조회 항목:

  • 계좌 목록 / 보유 주식
  • 시세(현재가/호가/체결/상하한가/캔들) / 종목 정보 / 매수 유의사항
  • 환율 / 장 운영 캘린더(KR·US)
  • 대기중 주문 조회 / 주문 상세 / 매수가능금액 / 판매가능수량 / 수수료
  • (tossctl fallback) 계좌 요약, 포트폴리오 비중, 관심종목

When to use

  • "토스증권 삼성전자 현재가 확인해줘"
  • "내 보유 주식 보여줘"
  • "대기중 주문 조회해줘"
  • "원달러 환율 알려줘"

1. Prefer the official Open API

Prerequisites

  • 토스증권 OpenAPI 콘솔에서 발급한 client_id / client_secret
  • Node.js 18+ (global fetch)

자격 증명은 사용자 환경변수로 두고 helper가 토스 서버로 직접 호출한다. 공유 프록시로 보내지 않는다.

환경변수설명
TOSSINVEST_CLIENT_IDclient id (필수)
TOSSINVEST_CLIENT_SECRETclient secret (필수)
TOSSINVEST_ACCOUNTaccountSeq. 계좌·자산·주문조회에 필요 (선택)
TOSSINVEST_API_BASE_URL기본 https://openapi.tossinvest.com (선택)

Workflow

helper는 내부적으로 POST /oauth2/token 으로 토큰을 발급(Client Credentials)받아 Authorization: Bearer 로 호출한다. 계좌·자산·주문조회 API는 X-Tossinvest-Account 헤더가 추가로 필요하다.

const {
  getPrices,
  listOfficialAccounts,
  getHoldings
} = require("toss-securities");

async function main() {
  const prices = await getPrices(["005930", "AAPL"]);

  const accounts = await listOfficialAccounts();
  const accountSeq = accounts.data.result[0].accountSeq;
  const holdings = await getHoldings({ account: accountSeq });

  console.log(prices.data);
  console.log(holdings.data);
}

main().catch((error) => {
  console.error(error);
  process.exitCode = 1;
});
  • 429 는 Retry-After/X-RateLimit-Reset 만큼 대기 후 백오프 재시도한다.
  • 401 은 토큰을 1회 재발급해 재시도한다.
  • client_secret/토큰은 에러 메시지에서 마스킹된다.

2. tossctl fallback

공식 credentials가 없으면 비공식 tossctl 을 fallback으로 쓴다.

Install tossctl first when missing

brew tap JungHoonGhae/tossinvest-cli
brew install tossctl
tossctl doctor
tossctl auth doctor
tossctl auth login

로그인 세션이 없으면 먼저 위 흐름을 끝낸다. 다른 비공식 크롤링이나 임의 HTTP 재구현으로 우회하지 않는다.

지원하는 read-only 명령:

  • tossctl account summary --output json
  • tossctl portfolio positions --output json
  • tossctl quote get TSLA --output json
  • tossctl watchlist list --output json
  • tossctl orders completed --market all --output json

패키지 wrapper(getAccountSummary, getPortfolioPositions, getQuote, listWatchlist 등)도 그대로 쓸 수 있다.

Answer conservatively

  • 계좌번호/민감정보는 꼭 필요한 범위만 노출한다.
  • 사용자가 "오늘" 같은 상대 날짜를 말하면 절대 날짜로 풀어 답한다.
  • 이 스킬은 조회 전용이다. 실거래 mutation 은 범위 밖이라고 분명히 말한다.

Done when

  • 공식 API credentials(또는 tossctl 로그인) 상태가 확인되었다.
  • 요청에 맞는 read-only 호출을 실행했다.
  • 결과를 한국어로 짧게 정리했다.

Failure modes

  • 공식 API credentials(TOSSINVEST_CLIENT_ID/SECRET)가 없으면 TossCredentialsError 로 명확히 실패한다.
  • 계좌·자산·주문조회 helper에 X-Tossinvest-Account 가 없으면 네트워크 호출 전에 실패한다.
  • tossctl fallback은 auth login 전이면 계좌/포트폴리오 조회가 실패할 수 있다.
  • 계좌/주문 정보는 민감하므로 출력 범위를 과도하게 넓히지 않는다.
