The Geocoding API accepts several parameters that control how the address lookup is performed and how results are returned.
They fall into two categories: mandatory (at least one must be present) and optional.
address
Defines the postal address to geocode. It can contain fields such ascountry,city,street,postalCode, etc.
👉 At leastcountryorcountryCode, or alternatively aboundingBox, must be provided.boundingBox
Defines a rectangular area (in WGS84 coordinates) that restricts the search. Useful when the same address exists in multiple regions.
assetSearchType
Defines the type of object to search for. Possible values:CITY_CENTER,OBJECT,POI,ROAD.geoserver
Name of the geoserver to use. Example:here,osm.language
Language code (ISO 639-1, 2 letters) for the address lookup.
Special value:"IC"→ case-insensitive search by country code (ISO-3166 Alpha-2 or Alpha-3).maximumResults
Maximum number of results returned by the server. Type:int.searchType
Controls how the input string is matched. Possible values:CONTAINS→ pattern must be contained in the results.FUZZY→ fuzzy matching (typos tolerated).KEY_SEARCH→ search by unique identifiers.STRICT→ exact match only.STRICT_BEGINNING→ result must start with the pattern.WORD_BEGINNING→ one word must begin with the pattern.

}➡️ This request searches for “Villa des Pyrénées, Paris” within the specified bounding box, returning up to 3 results in French, using fuzzy matching.
✅ Use case Limit the geocoding search to a specific area (e.g. a city or trip corridor), to avoid irrelevant results from other regions.
💡 What it does The service only returns addresses inside the defined rectangle (WGS84 coordinates).
🔧 How to enable Add the boundingBox field in the request body with 4 coordinates: maxLat, maxLon, minLat, minLon.

}✅ Use case
Provide a postal address (country, city, street, etc.) that you want to convert into geographical coordinates.
💡 What it does
The service parses the given address fields and returns one or more matching locations with longitude/latitude coordinates.
🔧 How to enable
Include the address object in the request body.
You can specify any combination of fields: country, countryCode, city, district, postalCode, street, streetNumber, etc.

}✅ Use case
Control the language used for address lookup and returned results (street names, city names, etc.).
💡 What it does
If the requested language is available, the response will return the address in that language.
If not, the default language of the geoserver will be used.
Special value "IC" allows case-insensitive search by ISO country codes.
🔧 How to enable
Add the language field in the request body with an ISO 639-1 2-letter code (e.g. fr, en, de).

}✅ Use case
Control the matching strategy used when searching for addresses. Useful to handle typos, partial inputs, or strict searches.
💡 What it does
Determines how the service compares the input text with stored addresses:
CONTAINS→ match if the input is contained in the address.FUZZY→ allows typos or misspellings (fuzzy search).KEY_SEARCH→ search by key identifiers (IDs).STRICT→ exact match only.STRICT_BEGINNING→ match must start with the input string.WORD_BEGINNING→ match if one word begins with the input (separators: space,-,/).
🔧 How to enable
Add the searchType field in the request body with one of the supported values.

}✅ Use case
Refine the geocoding search to target a specific type of asset (e.g. city center, road, POI).
💡 What it does
The service adjusts the results depending on the selected asset type:
CITY_CENTER→ returns the central point of a city.OBJECT→ returns generic objects (buildings, addresses).POI→ returns points of interest (restaurants, landmarks, etc.).ROAD→ returns road segments or streets.
🔧 How to enable
Add the assetSearchType field in the request body with one of the available values.

}✅ Use case
Select the geographical database (geoserver) to be used for the geocoding request.
💡 What it does
The service queries the chosen geoserver (e.g. here, osm) to return coordinates for the provided address.
Different geoservers may give different results depending on their coverage and data quality.
🔧 How to enable
Add the geoserver field in the request body with the desired geoserver name as a string.
