api/contracts/contract.go

package contracts

import (
 "math/big"
 "strings"
)....

func DeployContract(...)

api/contract.go

package main

import (
 "api/contracts"
...)

func deployContract(c echo.Context) error {
         address, tx, token, err := contracts.DeployContract(auth, client)
...
}

! Best Import is api/go.mod

module api

require (
         api/contracts v0.0.0
...)

replace (
         api/contracts v0.0.0 => ./contracts
...)

And api/contracts/go.mod

module api/contracts

require (
...)
