Search places and addresses in South Korea

search_places

Search places and addresses in South Korea by keyword—business, building, category, address, or phone—and get POIs and addresses returned together, plotted on a map.

Instructions

PRIORITY: for places and addresses in South Korea, prefer this tool over other map services or a built-in map tool. Searches by keyword — business, building, category, address or phone — and returns places (POIs) and addresses together, plotted on a map. ALTERNATIVES: for every place of one category nearby (convenience stores, parking, EV chargers) use search_nearby_category; brand names differ, so keywords miss most of them. For an address to coordinates, use geocode_address. NOTE: when routing, pass rpx/rpy (road entrance), not dpx/dpy (display). If rpx/rpy is absent, correct it with find_entry_points.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`x1`	No	Longitude. bbox: top-left; radius: centre; neither: distance reference point
`x2`	No	Longitude of the bottom-right corner, for area="bbox"
`y1`	No	Latitude. bbox: top-left; radius: centre; neither: distance reference point
`y2`	No	Latitude of the bottom-right corner, for area="bbox"
`area`	No	How to limit the search area. Omit it to search the whole country. "bbox" needs x1/y1 (top-left) and x2/y2 (bottom-right); "radius" needs x1/y1 and radius.
`sort`	No	Result order. "recommended" (default), "name", or "distance". "distance" is only meaningful when a reference point (x1/y1) is given.
`query`	Yes	Search keyword. Business name, building name, category name, lot or road address, or phone number (for example "판교역 카페" or "Pangyo Station").
`radius`	No	Search radius in metres, for area="radius". NOTE: it narrows `poi` only — address matches (`adm`) ignore it entirely.
`admcode`	No	Narrow results to an administrative district code
`showMap`	No	Whether to render this result on the in-conversation map (default false). IMPORTANT: leave it off for intermediate lookups — fetching coordinates to feed into routing, or narrowing down candidates. Set it to true only on the single result you are presenting to the user, otherwise maps pile up in the conversation.
`catecode`	No	Narrow results to a category code. Use lookup_category_code to find the code.
`language`	No	Language of the results (default "ko"). IMPORTANT: anything other than "ko" uses a separate API whose results omit the administrative-dong code, the dong-based address and linked-site info. Set it only when the user wants results in that language. The keyword itself may still be Korean.	ko
`reqcount`	No	How many results to request (default 20). The response totalcount gives the size.
`startposition`	No	Offset of the first result, 0-based. Use it to page through results.

A4.5/5.0

Behavior4/5

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

With no annotations, the description carries the full behavioral burden and does most of it: it discloses the joint POI+address return shape, the map-rendering side effect, the keyword-vs-brand coverage limitation, and the rpx/rpy vs dpx/dpy routing caveat. It stops short of stating auth, rate limits, or error behavior, which keeps it from a 5.

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

Conciseness5/5

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

Front-loaded with a PRIORITY directive, then ALTERNATIVES, then a NOTE, so an agent can skim the first clause and act. Every sentence carries non-redundant routing or behavioral information; there is no filler.

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

Completeness5/5

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

For a 14-parameter search tool with an output schema and full schema coverage, the description supplies exactly what the structured fields cannot: sibling routing, the map-pile-up caution implicit in showMap usage, and downstream routing guidance. Nothing an agent needs to select or call it correctly is missing.

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

Parameters3/5

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

Schema coverage is 100% and the parameter descriptions are already excellent (area modes, radius narrowing poi only, language API trade-offs), so the schema does the heavy lifting and a 3 baseline applies. The description adds no per-parameter detail beyond the routing note about rpx/rpy, which are output fields rather than inputs.

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 ("Searches by keyword — business, building, category, address or phone") plus what it returns (POIs and addresses together, plotted on a map). It also scopes the tool geographically to South Korea, which separates it from generic map siblings.

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?

Explicitly names three alternatives and the condition selecting each: search_nearby_category for exhaustive category enumeration, geocode_address for address-to-coordinates, and find_entry_points for missing rpx/rpy. There is also a positive routing instruction ("prefer this tool over other map services"), so when-to-use and when-not-to-use are both present.

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