You pay for uniqueness you do not ship
Most Riverflow 2.0 Pro outputs never leave staging—yet still hit the invoice.

Content Placeholders Without Burning Riverflow 2.0 Pro
Content drafts change faster than art direction. Using Riverflow 2.0 Pro for every placeholder turn burns budget on words that will rewrite tomorrow—especially when the theme is precision layout and typography-heavy mocks.
Where image API costs go off the rails
Storybook and docs should not generate
Component libraries need stable pictures, not live Riverflow 2.0 Pro samples on every build.
Marketing drafts churn images too early
Copy changes five times; Riverflow 2.0 Pro should not bill five hero generations for that.
Team keys multiply chaos
Shared Riverflow 2.0 Pro keys without quotas turn weekend hacks into multi-seat burn.
Scenario: Content placeholders with Riverflow 2.0 Pro
A marketing site, docs portal, or newsletter uses Riverflow 2.0 Pro to fill hero and card slots while copy is still fluid. Each editorial pass regenerates images “just in case.” Stakeholders review layout, not generative novelty—so unique synthesis is wasted. Swap non-final slots to Epochal catalog images: real, licensed, searchable, and flat-priced. When the headline freezes and the brand needs a one-of-a-kind frame, run Riverflow 2.0 Pro once, cache the winner, and stop the churn. Editors move faster because nobody is waiting on inference or arguing about credit burn mid-draft.
The fix: Epochal Stock at $50 USD/month (no per-image fee)
Epochal Stock Developer Image API is a single plan at $50 USD/month: full catalog access, 30 requests/minute per account, and unlimited original downloads with one concurrent transfer. There is no per-image fee and no free tier in v1. Use it wherever the picture does not need a unique Riverflow 2.0 Pro synthesis—prototypes, fixtures, placeholders—so generative spend stays reserved for finals. Authenticate server-side with a Bearer key only; never put keys in browser JavaScript.
- Price: $50 USD/month — single plan
- Per-image billing: none
- Rate limit: 30 requests/minute per account
- Downloads: unlimited originals, one concurrent transfer

FAQ
Are stock placeholders good enough before Riverflow 2.0 Pro finals?
For most drafts, yes. Stakeholders evaluate hierarchy and message first. Save Riverflow 2.0 Pro for the locked creative that must look model-native.
Is there a free Epochal tier for drafts?
No. v1 is a single paid plan at $50 USD/month with no free tier and no per-image credits.
How do downloads work for CMS pipelines?
Create a five-minute single-use download URL with your server Bearer key, then fetch the binary without the key. Unlimited originals serially; one concurrent transfer.
What if legal needs provenance for images near Riverflow 2.0 Pro experiments?
Catalog stock is easier to license and audit than endless one-off generations. Keep generative finals documented separately when you do use Riverflow 2.0 Pro.
