API use cases
The strongest API use cases are batch product photo prompts, ad creative teardown, brand-safe prompt templates, image-to-video motion direction, and workflow integration for agencies or ecommerce teams.
API early access
Image to prompt API for commercial teams
An image to prompt API is useful when a team needs repeatable prompt generation from product catalogs, ad references, landing page visuals, or storyboard frames. PromptLens is preparing this around commercial prompt outputs rather than generic captions.
What the API should return
A commercial API response should include prompt text, negative prompt, output type, detected visual signals, campaign brief, safety notes, and model-specific formatting for image and video tools.
Current status
The public page currently exposes the browser-based tool. API access should be launched only with auth, usage limits, cost controls, logging, abuse protection, and clear pricing.

Commercial packaging usually combines low free quota, history/export, support pages, and paid plans.
Keep payment disabled until auth, mail, D1 migrations, analytics, support/refund, and entitlement smoke tests pass.

Broad image-to-prompt pages train users to expect multiple model-specific and structured outputs.
Keep nine outputs, JSON export, alt text, and campaign briefs, but anchor them to ecommerce, ads, and AI video workflows.

API intent is BOFU
Users searching for an API are usually evaluating cost, quota, auth, reliability, and integration effort.
Keep API as early access until auth, rate limits, usage logs, billing, and abuse controls are ready.
Batch is the first paid wedge
Teams rarely need one prompt; they need repeatable output from image sets, catalogs, ads, and storyboards.
Use batch variants, saved briefs, templates, and prompt format consistency as the API foundation.
Privacy copy must change
Browser-only tools can promise less data handling; API tools must explain upload, storage, retention, and deletion.
Keep the public fast path browser-first and update privacy/terms before server-side API image handling launches.
Comparison
Use this as a decision page, not a feature checklist. The key question is whether the reference image needs to become a repeatable commercial workflow.

FAQ
Is the PromptLens image to prompt API live?
Not yet. This page is an early-access demand page. The web tool is live; API should be opened after auth, rate limits, billing, and abuse controls are production-ready.
Who should request API access?
Teams processing many product photos, ad references, marketplace images, or video storyboards are the best fit.
Will the API upload images to PromptLens?
An API workflow requires server-side image handling. The privacy policy must be updated before API launch to explain storage, retention, and deletion behavior.
