Based on the information in the knowledge sources, Airbyte Cloud charges $15 per million rows for APIs and custom sources. The documentation does not explicitly state whether this is a flat fee for up to 1 million rows (i.e., $15 minimum per sync) or if the pricing is prorated for partial millions (e.g., $3.75 for 0.25M rows). However, the table and language used (“$15 per million rows”) strongly suggest that the pricing is prorated based on the actual number of rows synced. For example, syncing 0.25M rows would likely cost $3.75. If you need absolute confirmation, it is recommended to reach out to Airbyte Sales or Support for clarification, as the documentation does not explicitly confirm the prorating mechanism for partial usage[Manage credits – What are credits?](
