This endpoint allows you to get the full place hierarchies for: * a given coordinate * list of `place_id`. A place hierarchy is a list of place identifiers and types from the `planet` level down to the `level` specified in your query (note that `level` defaults to `locality` if not specified in your query). The response might include more than one hierarchy for a given coordinate. The reason for this is that we try to match the closest place's hierarchy but we also include the closest major city's hierarchy within a radius of 50km. This only applies if the `level` is below `region` and, if it exists, the major city's hierarchy is always the second item in the list. For instance, if you specify `?location.origin=47.615337,-122.203981`, which is a coordinate located in Bellevue, Washington, you get two hierarchies, one for Bellevue but also one for [Seattle](https://en.wikipedia.org/wiki/Seattle). ## Get Place Hierarchies > Return the administrative hierarchy chain for one or more places.\ > \ > Exactly one of \`location.place\_id\` or \`location.origin\` must be provided — supplying both\ > or neither returns \`400\`.\ > \ > \*\*By place ID\*\* (\`location.place\_id\`):\ > Returns stored hierarchies for the given place IDs.

GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.predicthq.com/api/places/get-place-hierarchies.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
