Spark API access costs $50/mo for each MLS a developer can access. Multiple API keys for one MLS will incur only one $50/mo charge.

Access to each MLS will come with a high number of included requests. Monthly API request limits are determined by the number of accessible MLSs, Broker/Agent’s Own Data subscriptions, and MLS-created developer-accepted API keys. Developers pay a per-request fee once that limit is exceeded. Overage fees will apply only for very high monthly request volumes. Monthly usage and quotas are reviewable from the developer’s Spark Platform dashboard.

Broker/Agent’s Own Data API keys (PDAP) will not be charged at all, except in cases of extreme request volume.

API keys created by the MLS and accepted by a developer via email invitation are subject to a $50/mo fee. These are separate from all other regular data plan subscription charges and request volume counts.
