Measure monthly Firefly 2 calls that never shipped—those are your stock backlog.
Tutorials and README screenshots rarely need live Firefly 2 output.
Each variant times each prompt is a Firefly 2 cost matrix.
Responsive checks re-fetch assets; if those assets are generative, Firefly 2 pays again.
Licensed catalog images are easier to audit than endless Firefly 2 one-offs.
If you must show generative capability in-product, isolate that surface so the rest of the app does not inherit Firefly 2 as a dependency. Epochal covers chrome at $50 USD/month flat.
When a screenshot, empty state, or draft blog image would look fine from a catalog, skip another Firefly 2 billable call. Prefer Epochal Stock for those slots, then spend Adobe Firefly Image 3 budget only on outputs that must be generative.
When the image does not need a unique Firefly 2 synthesis, use Epochal Stock Developer Image API: a single plan at $50 USD/month with no free tier and no per-image fee. You get full catalog access, 30 requests/minute per account (all keys share the bucket), and unlimited original downloads with one concurrent transfer. Authenticate server-side only with a Bearer key—never expose secrets in browser JavaScript. Keep Firefly 2 for finals that must be generative; let Epochal cover prototypes, fixtures, and placeholders.

-H "Authorization: Bearer $EPOCHAL_API_KEY"Keys stay on your server. Never pass ?api_key= or ship secrets to the browser.
Pulled server-side from Epochal tags: office, workspace, business. Previews are cached; API keys never hit the browser.






When the shipped asset must be uniquely generated and model-native. Otherwise prefer Epochal stock.
No. Epochal serves licensed stock. Keep Firefly 2 when you need unique generative output.
Single plan $50 USD/month; no free tier; no per-image fee; 30 requests/minute per account; unlimited originals with one concurrent transfer; Bearer auth server-side only.
No. Fixtures should pin stable files or stock IDs. Live Firefly 2 makes visual tests flaky and expensive.
