The fourbyte package provides access to all the endpoints listed above.

Basic Function Signature Lookup

package main

import (
	"context"
	"fmt"
	"log"

	"github.com/0xhyim/fourbyte"
)

func main() {
	response, err := fourbyte.GetFunctionSignatures(context.Background(), fourbyte.WithHexSignature("0x1249c58b"))
	if err != nil {
		log.Fatal(err)
	}
	// "mint()"
	fmt.Println(response.Signatures[0].TextSignature)
}

Signature Lookup (following Next)

package main

import (
	"context"
	"fmt"
	"log"

	"github.com/0xhyim/fourbyte"
)

func main() {
	signatures := []fourbyte.Signature{}
	response, err := fourbyte.GetFunctionSignatures(context.Background(), fourbyte.WithTextSignature("WETH"))
	if err != nil {
		log.Fatal(err)
	}
	signatures = append(signatures, response.Signatures...)
	for response.Next != nil {
		response, err = response.Next.Follow(context.Background())
		if err != nil {
			log.Fatal(err)
		}
		signatures = append(signatures, response.Signatures...)
	}
	fmt.Println(signatures)
}
