MOZ has a few different pricing plans, which affects how customers interact with MOZ's API. You can see the difference here.
MOZ's API access is controlled through different rate plans. The free version provides you with 1 call per 10 seconds and up to 25,000 rows per month, with access scaling from there depending on your rate plan.
If you have the free plan through MOZ, you'll be able to access Link Metrics and URL Metrics endpoints through Grow. However, MOZ's API only allows paid versions to access the Anchor Text, Top Pages Metrics, and Index Metadata endpoints.
