We are developing an application, that needs to find the speed around a specific location... We were planning to use OverPass API to first the speed and tried to follow the article mentioned below.
Overpass api to find the speed limit for a co-ordinate?
The syntax of the around method is shown below.
http://www.overpass-api.de/api/xapi?*[maxspeed=*][around=2500,8.5580957,76.880541]
But we are not getting any results... Can anyone guide us if the syntax is correct?
The failure reason: around is not a supported predicate in XAPI (please, see the original manual, https://wiki.openstreetmap.org/wiki/Xapi). So you cannot use it in your queries.
Solution 1: You can replace around with supported bbox. For example, the query below works properly.
http://www.overpass-api.de/api/xapi?*[bbox=-0.489,51.28,-0.436,51.36][maxspeed=*]
You will receive ~300kB of data
Solution 2: If you still want around, please use Overpass QL/XML:
way(around:2500,8.5580957,76.880541)[maxspeed];out;. You can try it at http://www.overpass-api.de/query_form.htmlOverpass XML query:
<query type="way">
<around radius="2500" lat="8.5580957" lon="76.880541" />
<has-kv k="maxspeed" />
</query>

As for me, Overpass XML looks like more readable. Also XML is preferred because XSLT can transform it to any other regular format.
