Latency budgets become money budgets
Slow Pruna p-image retries encourage parallel calls—and parallel charges.

Prototyping with Pruna p-image Without Torchling Credits
Prototyping is where Pruna p-image spend quietly starts. Agents and scaffolds regenerate heroes on every layout pass—even when the only goal is to prove a flow for production-speed app image loops.
Where image API costs go off the rails
Quality tiers tempt overspend
Defaulting to the highest Pruna p-image tier for every draft wastes premium capacity.
No cache means no ceiling
Without a stock layer, every page view path can re-trigger Pruna p-image.
Investors notice messy COGS
Unpredictable Pruna p-image lines make early unit economics look worse than they need to.
Scenario: Prototyping with Pruna p-image
A vibecoder wires Pruna p-image into a Next.js or Flutter scaffold so every screen looks “real.” Cursor agents retry failed layouts and re-prompt the same empty states. Within a day, exploratory calls outnumber shipped screens. For wireframes, fake dashboards, and “looks real enough” investor demos, a flat stock API is more predictable than Pruna p-image credits. Pin a small set of licensed images, reuse them across branches, and only call Pruna p-image when a unique concept is the point of the prototype.
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 Pruna p-image 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
- Best for: tests, prototypes, and placeholders instead of another Pruna p-image generation

FAQ
Should prototypes call Pruna p-image live?
Only for the few frames that must prove generative capability. Everything else should be stock or cached fixtures so Pruna p-image is not on the hot path.
What does Epochal cost for prototype work?
One plan: $50 USD/month, no free tier, no per-image fee, 30 requests/minute per account, unlimited original downloads with one concurrent transfer.
Can I keep keys in the browser during a demo?
No. Epochal requires a server-side Bearer key. Generate short-lived download URLs on the server; never ship secrets in client JavaScript.
When do I switch back to Pruna p-image?
When a screen needs a model-native look that stock cannot match—brand mashups, novel characters, or prompt R&D you intend to ship.
