# TossInvest Web API

## Overview

Use the bundled scripts for public data visible on `tossinvest.com`. Choose the task and its references from the routing table below.

Use Python 3.14.7, the sole supported runtime, with network access.

When checking page coverage, observed tabs, paging or remaining verification gaps,
read the [2026-09-16 public-page audit](references/public-pages-audit-2026-09-16.md).
News and filings resolve metadata `companyCode`; stock comments resolve metadata
`guid`. Neither identifier can be inferred safely from a product code.

## Official Open API Boundary

This skill wraps public web data, not TossInvest's separate OAuth-based Open API.
For official integration, authentication or rate-limit questions, read
[the official boundary](references/official-openapi-boundary.md) and
`developers.tossinvest.com/docs`. For official documentation changes and saved
comparison evidence, use [the official update audit](references/official-api-audit-2026-09-16.md).

## When Not To Use

- Never combine this skill with tools or workflows for login, authentication, account balance, holdings, transfers, certificates, order placement, amendment, or cancellation.
- Do not use it to provide personalized investment advice, buy/sell recommendations, or portfolio decisions.
