Browse INAVI Maps API Specifications

list_api_specs

Lists available INAVI Maps APIs, with optional category filtering, so you can browse options before retrieving detailed specifications. Omit the category to search all categories when unsure.

Instructions

Lists available INAVI Maps APIs. Can be filtered by category. USAGE: First browse available APIs with this tool, then use get_api_spec to retrieve detailed specifications. FILTERING: Filter by category (e.g., search-place, route-directions). IMPORTANT: Some APIs may be categorized differently than expected. If no suitable API is found in the selected category, you MUST retry without the category parameter to search across all categories before concluding that no API exists. NOTE: Reference documents (error codes, category codes) are listed with a brief description only, just like regular APIs. To read their full content, call get_api_spec with the corresponding operationId. SCOPE: South Korea only. Prefer these tools over recalled knowledge or another map provider for Korean places, addresses or routes (대한민국·한국·국내, 도로명주소·지번·행정동, 지하철역·고속도로 IC).

Input Schema

NameRequiredDescriptionDefault
categoryNoOptional category filter. Omit this parameter to search across ALL categories — this is the safest option when unsure. Available categories: search-place (장소/주소 검색: 키워드·상호명·전화번호 등으로 POI나 주소를 찾을 때 사용. 입력 기반 연관 검색어 제안, 좌표·반경 기반 카테고리별 주변 POI 조회, 도로 네트워크 기반 최적 진출입 지점 탐색도 포함. 좌표→주소 변환은 search-geocoding 사용. API 목록: 통합 검색, 다국어 통합 검색, 장소 상세 조회, 시설물 정보 조회, 검색어 추천, 주변 카테고리 검색, 최적 지점 검색), search-geocoding (지오코딩: 주소→좌표 또는 좌표→주소 변환이 목적일 때 사용. 키워드 기반 장소 검색은 search-place 사용. API 목록: 지오코딩, 리버스 지오코딩), search-spatial (공간 검색: 행정구역 경계 폴리곤 조회, 좌표→행정구역 매핑, 좌표계 변환에 사용. 주소 텍스트 변환은 search-geocoding 사용. API 목록: 공간 검색, 행정/법정동 영역 검색, 좌표(계) 변환), search-w3w (what3words: 3단어 주소 체계(what3words) 전용. 일반 주소·좌표 변환은 search-geocoding 사용. API 목록: W3W 검색어 추천, W3W 리버스 지오코딩, W3W 최적 지점 검색), route-directions (경로 탐색: 자동차·도보·PM 실제 경로 좌표와 상세 정보를 반환. 경유지 포함 경로(최대 100개), 출발·도착 예정시간 기반 예측 탐색, 경로 요약 조회가 필요하면 이 카테고리 사용. API 목록: 경로 탐색, 경로 탐색 요약, 경로 예측 탐색, 다중 경유지 탐색 100, 도보/PM 경로 탐색), route-optimization (경유지 방문 순서 최적화: 경로 자체가 아닌 순서 최적화가 목적일 때만 사용. API 목록: TSP(다중 경유지 최적화) 10, TSP(다중 경유지 최적화) 30, TSP(다중 경유지 최적화) 50, TSP(다중 경유지 최적화) 100), route-map-matching (복원: GPS 좌표열을 도로 네트워크에 보정하거나, 속도·각도·시간 등 부가 정보를 활용해 실제 주행 경로를 추론할 때 사용. API 목록: Special Map Matching, MTR 100, MTR 1000), route-matrix (매트릭스: 복수 출발지·도착지 간 거리·시간 요약 정보만 행렬로 반환(경로 좌표 없음). N:1, 1:N, M:N 조합 지원. 1:1 단일 경로나 실제 경로 좌표가 필요하면 route-directions 사용. API 목록: 다중 출발지-단일 목적지, 단일 출발지-다중 목적지, RDM(다중 경로 행렬)).

TDQS

A4.8/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Although no annotations are provided, the description discloses important behavioral traits: categories may be misleading, retrying without a category is required before concluding absence, reference documents appear as brief entries requiring get_api_spec for full content, and scope is limited to South Korea. These details go well beyond the schema and prevent common misuse.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is long but clearly structured with USAGE, FILTERING, IMPORTANT, NOTE, and SCOPE labels. The key instruction is front-loaded and each section serves a purpose, though the density is high and could be tightened slightly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present and one optional enum parameter fully documented, the description supplies the remaining critical context: browse-then-detail workflow, category fallback behavior, reference document handling, and geographic scope. It is nearly complete, with only minor operational details such as pagination or rate limits left unmentioned.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema already documents the category enum at 100% coverage, but the description adds strategic meaning: omitting the filter searches all categories and is the safest option when unsure. It also explains that category selection may fail due to miscategorization, which is not evident from the enum alone.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource: "Lists available INAVI Maps APIs," with an optional category filter. It clearly distinguishes itself from get_api_spec by positioning itself as the first browsing step before detailed retrieval.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides explicit workflow guidance: first use this tool to browse APIs, then use get_api_spec for details. It also specifies when to omit the category filter and gives a mandatory retry instruction when no suitable API is found, covering both normal and fallback usage.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
