I’m trying to get a number inside a url
https://pokeapi.co/api/v2/ability/35/ This number may vary from 1 4 digits ago. I want to catch the number 35 but with my current regex I’m catching the 2 + 35 (235) follow the regex I’m using:
/[^\d]/g
This url has no other variation

You can use the function split for that purpose.
This function will split the string into an array, given a certain separator.
var url = 'https://pokeapi.co/api/v2/ability/35/';
var pathArray = url.split('/');
console.log(pathArray[6]);

The regex below identifies all strings composed by digits of 0 to 9 1 to 4 characters long, surrounded by bars (/).
/(?<=\/)\d{1,4}(?=\/)/g
In this way, the digits of alphanumeric parts, such as the 2 of v2.

Depending on the language there are more appropriate functions for url handling

Does the number need to have two digits? Or does it need to be between bars? Well, from your statement (number inside string), it seems correct to take 2 and 35.

Could [Edit] and put the tool or language you are using? And if it is a language (seems to be Javascript, but please confirm), also put the code you used, because
[^\d]takes everything that nay is digit, see: https://regex101.com/r/GZ0TYq/1 - that being said, is the tip of the comment above: all languages have some form of URL manipulation, which is much better than using regex– hkotsubo
It would also be interesting to put all the rules: the number is always at the end of the URL? How many digits? Can they have other digits (besides v2) in other parts? Is it to get them too? etc...

Yes I am using javascript. And the number I need is only the 35 I can even treat that data to take the 2 from the beginning but I wanted to save lines of code. 35 can range from 1 numbers there are up to a 4 digits.

In case I only need the final number there is no number beyond the end and v2
