How do I calculate the price of a sandbox?

import { Sandbox } from 'e2b'

const sandbox = await Sandbox.create()
const info = await sandbox.getInfo()

console.log(info.cpuCount)  // e.g. 2
console.log(info.memoryMB)  // e.g. 512

from e2b import Sandbox

sandbox = Sandbox()
info = sandbox.get_info()

print(info.cpu_count)  # e.g. 2
print(info.memory_mb)  # e.g. 512

import express from 'express'

const VCPU_RATE_PER_SECOND = 0.000014      // USD per vCPU per second
const RAM_RATE_PER_GIB_SECOND = 0.0000045  // USD per GiB per second

function sandboxCost({ vcpu_count, memory_mb, execution_time }) {
  const seconds = execution_time / 1000
  const ramGiB = memory_mb / 1024
  return (vcpu_count * VCPU_RATE_PER_SECOND + ramGiB * RAM_RATE_PER_GIB_SECOND) * seconds
}

const app = express()
app.use(express.json())

app.post('/webhook', (req, res) => {
  const event = req.body

  // Resources and duration are only on the terminating events
  if (event.type === 'sandbox.lifecycle.killed' || event.type === 'sandbox.lifecycle.paused') {
    const cost = sandboxCost(event.event_data.execution)
    console.log(`Sandbox ${event.sandbox_id} cost $${cost.toFixed(6)}`)
  }

  res.sendStatus(200)
})

app.listen(3000)

from flask import Flask, request

VCPU_RATE_PER_SECOND = 0.000014      # USD per vCPU per second
RAM_RATE_PER_GIB_SECOND = 0.0000045  # USD per GiB per second

def sandbox_cost(execution: dict) -> float:
    seconds = execution["execution_time"] / 1000
    ram_gib = execution["memory_mb"] / 1024
    return (
        execution["vcpu_count"] * VCPU_RATE_PER_SECOND
        + ram_gib * RAM_RATE_PER_GIB_SECOND
    ) * seconds

app = Flask(__name__)

@app.post("/webhook")
def webhook():
    event = request.get_json()

    # Resources and duration are only on the terminating events
    if event["type"] in ("sandbox.lifecycle.killed", "sandbox.lifecycle.paused"):
        cost = sandbox_cost(event["event_data"]["execution"])
        print(f"Sandbox {event['sandbox_id']} cost ${cost:.6f}")

    return "", 200
