Sure I'm a newbie in Go and Echo, but in my opinion it's bad idea because of Echo is just simple router we can validate request (form) using 3rd party package like https://github.com/asaskevich/govalidator or something like that.

package main

import (
    "net/http"

    "github.com/asaskevich/govalidator"

    "github.com/labstack/echo"
    "github.com/labstack/echo/engine/standard"
)

type Form struct {
    Name  string `json:"name" valid:"optional,alphanum"`
    Email string `json:"email "valid:"required,email"`
    Card  string `json:"card" valid:"required,creditcard"`
    Code  string `json:"code" valid:"numeric,length(3|4)"`
}

func main() {
    router := echo.New()

    router.POST("/", formHandler)

    router.Run(standard.New(":8000"))
}

func formHandler(c echo.Context) error {
    form := Form{}

    if err := c.Bind(&form); err != nil {
        return c.String(http.StatusBadRequest, err.Error())
    }

    _, err := govalidator.ValidateStruct(form)

    if err != nil {
        return c.String(http.StatusBadRequest, err.Error())
    }

    return c.String(http.StatusOK, "Ok")
}
