API Limits and Overage Pricing

Limits are enforced per workspace and plan.

• Plan prices (subscription amounts): Pricing
• Quotas and metered overage rates (this page): technical limits aligned with API enforcement
• Product behavior: Docs and guides — link here or to Pricing instead of duplicating numbers

​

File and storage limits

Storage overage uses the workspace’s monthly peak usage above its included allowance and applies only when metered overage is enabled. See Files & storage for how uploads, outputs, and WordPress isolated buckets count toward HDAM storage.

​

Media API limits

Media API requests count conversion, compression, async job creation, media tools, and workflow runs (POST /api/workflows/{id}/run). They share one monthly pool. Processed transfer is the total bytes read and written while handling those API requests (not Image CDN edge delivery or video streaming playback).

​

Image CDN

Origin deliveries are requests that reach Convertly to fetch or transform a source. Repeat hits served from edge cache do not count again. Generated output counts bytes produced only when Convertly renders a new persistent variant. Edge and persistent-cache hits do not count again. Edge delivery safety limits count every CDN response, including cache hits, plus the bytes delivered. They are not overage billing meters. The ceilings protect workspaces from hotlinking, automated redistribution, and denial-of-wallet traffic. Transform parameters are canonicalized before cache lookup. Out-of-range or differently formatted values that resolve to the same transform share one cache identity instead of creating duplicate variants. Custom domains start on Starter. Pro and Business can opt into overage billing and set a monthly Image CDN overage spending limit. The dashboard reports origin requests, newly generated output, total edge deliveries, and delivered data independently. See Custom domain and URL structure.

​

Video streaming

Source minutes bill once per minute of source video packaged, regardless of rendition count. Active stored minutes cap the source-video duration retained in Stream at one time, so hosted videos cannot accumulate indefinitely across billing cycles. Deleting a stream frees that capacity. Delivery minutes bill viewer watch time (a 10-minute video watched fully by 100 viewers uses 1,000 delivery minutes). All plans can generate up to 7 adaptive renditions through 2160p / HDR10 when the source contains those pixels. Convertly does not upscale a lower-resolution source into fake 4K. See Video streaming.

Forma AI

Forma AI units cover assistant and analysis calls, generative studio operations, and ML cutout previews launched from the file lightbox. Standard studio upscaling is free. CDN URL params such as upscale=ai bill through signed delivery, while POST /api/media/remove-background counts as a Media API operation instead. See Forma AI.

Workflows

Test runs in the dashboard do not send external webhooks and are for validation only.
