We study the existence of a weak solution of a nonlocal problem

$$\begin{eqnarray}\displaystyle & \displaystyle -{\mathcal{L}}_{K}u-\unicode[STIX]{x1D707}ug_{1}+h(u)g_{2}=f\quad \text{in }\unicode[STIX]{x1D6FA}, & \displaystyle \nonumber\\ \displaystyle & \displaystyle u=0\quad \text{in }\mathbb{R}^{n}\setminus \unicode[STIX]{x1D6FA}, & \displaystyle \nonumber\end{eqnarray}$$
where ${\mathcal{L}}_{k}$ is a general nonlocal integrodifferential operator of fractional type, $\unicode[STIX]{x1D707}$ is a real parameter and $\unicode[STIX]{x1D6FA}$ is an open bounded subset of $\mathbb{R}^{n}$ ($n>2s$, where $s\in (0,1)$ is fixed) with Lipschitz boundary $\unicode[STIX]{x2202}\unicode[STIX]{x1D6FA}$. Here $f,g_{1},g_{2}:\unicode[STIX]{x1D6FA}\rightarrow \mathbb{R}$ and $h:\mathbb{R}\rightarrow \mathbb{R}$ are functions satisfying suitable hypotheses.
