Spring boot call external API with external YAML API definition

Question

I am trying to find way, how to call external API based on YAML definition:

• I have (Spring boot, external) API-1, generated with OpenAPI plugin, which has it's YAML file.
• I have (Spring boot) API-2, which calls API-1. But all I have is YAML definition of API-1.

We know external API can be called with:

@Bean
public WebClient remoteApiBean() {
    return WebClient.create("http://example.com/api");
}

And e.g. Service implementation:

@Autowired
public MyService(WebClient remoteApiBean) {
    this.remoteApiBean = remoteApiBean;
}

And requesting resource

this.remoteApiBean.get()
            .uri("/request")
            .retrieve()
            .bodyToMono(ModelDTO.class)
            .block(REQUEST_TIMEOUT);

API and model info are stored inside of API-1 YAML config. My question is, if it is possible to use API-1 YAML definition as a resource for API-2. Generate code above and also generate DTOs. I think, there MUST be any plugin which generate this, but I am unable to find it, because there are very similar issues with Spring Boot yaml external configurations and google result are bad according this searching.
