<p dir="auto">I have updated the example URLs from above to only require start lat/lon and end lat/lon values as well as a profile.</p>
<ul dir="auto">
<li>Valhalla: <code class="notranslate">https://valhalla.openstreetmap.de/directions?profile=pedestrian&wps=120.8635823%2C24.1893169%2C120.8648163%2C24.1825192</code></li>
<li>OSRM: <code class="notranslate">https://routing.openstreetmap.de/?loc=24.189317%2C120.863582&loc=24.182519%2C120.864816&srv=2</code></li>
<li>GraphHopper: <code class="notranslate">https://graphhopper.com/maps/?point=24.18978%2C120.86377&point=24.18252%2C120.86482&profile=foot</code></li>
</ul>
<p dir="auto">For the profile values, I'd suggest the following mapping table:</p>
<markdown-accessiblity-table><table role="table">
<thead>
<tr>
<th> </th>
<th>Car</th>
<th>Bicycle</th>
<th>Foot</th>
</tr>
</thead>
<tbody>
<tr>
<td>Valhalla</td>
<td>car</td>
<td>bicycle</td>
<td>pedestrian</td>
</tr>
<tr>
<td>OSRM</td>
<td>0</td>
<td>1</td>
<td>2</td>
</tr>
<tr>
<td>GraphHopper</td>
<td>car</td>
<td>bike</td>
<td>foot</td>
</tr>
</tbody>
</table></markdown-accessiblity-table>
<p dir="auto">OSRM (FOSSGIS) is a bit special, since the values appear to be derived from the sequence in <a href="https://github.com/fossgis-routing-server/cbf-routing-profiles/blob/master/profiles.conf.example#L2">https://github.com/fossgis-routing-server/cbf-routing-profiles/blob/master/profiles.conf.example#L2</a> ... the profile values are valid for the FOSSGIS instance only.</p>
<p dir="auto">I think that's probably all we need to generate URLs similar to Nominatim.</p>
