## ExchangeAuthCodeForAPIKey

Exchange an authorization code from the PKCE flow for a user-controlled API key

### Example Usage

```go theme={null}
package main

import(
	"context"
	"os"
	openrouter "github.com/OpenRouterTeam/go-sdk"
	"github.com/OpenRouterTeam/go-sdk/models/operations"
	"github.com/OpenRouterTeam/go-sdk/optionalnullable"
	"log"
)

func main() {
    ctx := context.Background()

    s := openrouter.New(
        openrouter.WithSecurity(os.Getenv("OPENROUTER_API_KEY")),
    )

    res, err := s.OAuth.ExchangeAuthCodeForAPIKey(ctx, operations.ExchangeAuthCodeForAPIKeyRequest{
        Code: "auth_code_abc123def456",
        CodeChallengeMethod: optionalnullable.From(openrouter.Pointer(operations.ExchangeAuthCodeForAPIKeyCodeChallengeMethodS256)),
        CodeVerifier: openrouter.Pointer("dBjftJeZ4CVP-mB92K27uhbUJU1p1r_wW1gFWFOEjXk"),
    })
    if err != nil {
        log.Fatal(err)
    }
    if res != nil {
        // handle response
    }
}
```

## CreateAuthCode

Create an authorization code for the PKCE flow to generate a user-controlled API key

)

func main() {
    ctx := context.Background()

    s := openrouter.New(
        openrouter.WithSecurity(os.Getenv("OPENROUTER_API_KEY")),
    )

    res, err := s.OAuth.CreateAuthCode(ctx, operations.CreateAuthKeysCodeRequest{
