ceven

Graphhopper

Calculates optimal travel paths and delivery clusters for your fleet, converts addresses to coordinates, and maps reachable zones based on time or distance.

Why use Ceven?

  1. AI native Graphhopper integration

    • Describe the outcome and Ceven picks the right Graphhopper calls, fills the parameters, and checks the result.
    • Structured, agent friendly tool schemas so each call runs reliably instead of by guesswork.
    • Rich coverage for reading, writing, and querying your Graphhopper data, across all 13 of its actions.

  2. Managed auth

    • Built in OAuth with automatic token refresh and rotation.
    • One place to manage, scope, and revoke Graphhopper access.
    • Per user and per environment credentials instead of shared keys.

  3. Agent optimized design

    • Actions are tuned from real success and error rates so reliability climbs over time.
    • Full execution logs so you always know what ran in Graphhopper, when, and on whose behalf.
    • The agent pauses and asks when Graphhopper is unclear instead of plowing ahead.

  4. Enterprise grade security

    • Fine grained access so you control which agents and people can reach Graphhopper.
    • Least privilege by default, read scopes first and only the writes a workflow needs.
    • A full audit trail of every Graphhopper action to support review and sign off.

Supported tools

Every action Ceven's agents can run on Graphhopper, and when to use it.

Calculate Route
Use this when you need to find the fastest or shortest path between two or more points for a specific vehicle type.
Solve VRP
Initiate vehicle routing problem optimization to assign multiple stops to a fleet while minimizing total travel time.
Geocode Address
Convert a text address into latitude and longitude coordinates or perform reverse lookups for a specific point.
Get Isochrone
Compute a polygon representing all areas reachable from a point within a set time or distance limit.
Calculate Matrix
Pull a batch of distances and travel times between multiple origins and destinations in one request.
Cluster Capacity
Assign a set of customers into clusters to minimize total distance while respecting vehicle or worker capacity.
List Custom Profiles
Pull a list of all user defined routing profiles to ensure the agent uses the correct vehicle constraints.
Upload GPX
Upload a GPX file to get a public URL for use in routing requests that require a hosted file key.
Get Route Details
Pull granular turn by turn instructions and geometry for a previously calculated route.
Verify Coordinate
Check if a given latitude and longitude pair falls within a routable road network.
Update Routing Profile
Modify the parameters of a custom routing profile to change speed or road preference settings.
Clear Route Cache
Force the system to ignore cached routing results and calculate a fresh path based on latest map data.
Capacity Clustering
Tool to solve capacity clustering problem. Use when assigning a set of customers to clusters to minimize total distance synchronously.
GraphHopper Geocoding
Tool to perform forward or reverse geocoding. Use when converting between textual addresses and latitude/longitude coordinates.
Get Custom Profiles
Tool to retrieve a list of all user defined routing profiles. Use when you need to list custom profiles.
POST Route
Tool to calculate complex routes via POST /route. Use when you need advanced route planning with custom parameters.
Upload GPX File
Tool to upload a GPX file to a public file hosting endpoint. Returns a public URL which can be used where a 's3key' is required.
GraphHopper VRP POST
Tool to initiate VRP optimization. Use when you need to solve vehicle routing problems synchronously.

Frequently asked questions

Ceven stores your GraphHopper API key in an encrypted vault. When a workflow triggers a routing request, the agent retrieves the key and injects it into the request header. This ensures that all requests are billed to your specific account and respect your chosen plan limits. You can update or rotate your key at any time within the Ceven integration settings without needing to rewrite your active workflows. We never share this key with other users or external services, keeping your routing credits secure and private.
Yes. You can create custom profiles in your GraphHopper dashboard for different vehicle types like heavy trucks or bicycles. Once created, use the List Custom Profiles action to find the profile ID. You then pass this ID into the Route or VRP actions. This ensures the agent does not route a semi truck down a narrow residential street or a pedestrian onto a highway. The agent automatically maps the profile to the request to ensure the calculated travel times are accurate for that specific vehicle.
If GraphHopper cannot find a precise match for an address, the agent is programmed to attempt a fuzzy search. If that also fails, the workflow enters a retry loop or flags the record for human review depending on how you configured the error path. You can set the agent to use the closest known point on the road network as a fallback. This prevents the entire routing sequence from crashing just because one customer provided a typo in their street address during the checkout process.
Yes. GraphHopper imposes a limit on the size of the distance matrix based on your subscription tier. For example, free or lower tiers have a strict maximum for the number of origins and destinations in a single POST request. If your workflow exceeds this limit, the Ceven agent automatically splits the request into smaller chunks and aggregates the results back into a single table for you. This allows you to process large batches of locations without manually managing the API constraints or hitting 413 request entity too large errors.
The isochrones are highly accurate because they use real road network data rather than simple radius circles. They account for one way streets, speed limits, and known barriers. To get the best results, specify the vehicle profile and the time of day if your plan supports traffic data. The agent returns these as GeoJSON polygons which you can then push directly into a map tool or use to trigger a workflow when a new lead falls within your primary service zone.
Ceven can take a local GPX file from your storage, upload it via the GraphHopper Upload GPX tool, and then use the resulting public URL to calculate a route that follows that specific path. This is useful for tourism apps or delivery routes that must follow a very specific scenic or regulated path. The agent manages the lifecycle of the upload and ensures the routing engine has the correct reference key before attempting to calculate the travel time or distance for that specific track.
Yes. When the agent calls the VRP POST endpoint, it can include time window constraints for every stop. This means you can tell the agent that a customer must receive their package between 9 AM and 11 AM. The optimizer will then rearrange the stop sequence to satisfy these constraints while still minimizing the total distance. If a solution is mathematically impossible, the agent will notify you which specific stop is causing the conflict so you can manually adjust the window.
