We've just updated our pricing page to reflect our new pricing model.
Broadly speaking: the plans have been simplified. All plans now allow image download. We've removed the old unlimited plan, and replaced it with two higher tiers, both finite in the number of requests they offer. The free evaluation tier remains.
In addition we now mandate a limit to the number of requests that can be made per second. If you exceed this, OneMusicAPI will respond with a HTTP 429 (Too Many Requests) response. You are free to re-query at your convenience; but note that in the case of distributed clients without orchestration you may find yourself having to requery several times; in these cases we suggest use of a backoff algorithm.
Existing customers will see no change to their service or plans. They continue to not have a per-second limit. Where existing customers wish to change plans, they must change to one of our new ones, or get in touch.
