This free tier gives a small but real monthly allowance: 100 MB of testing quota and API sandbox access, with no credit card required. Compared with the cheapest paid Micro plan at $5/month for 500 MB, the free account provides about 20% of that starter capacity, so its practical value is roughly $1/month.

  • 100 MB of testing quota for the free account.
  • Free API sandbox access with 100 MB of free quota for real optimizations.
  • No credit card required to sign up for the free account.
