headline_variants
shallowio.github.hermoso-ai/hermoso · Verify this server
Turn ONE finished static ad into several copies that differ ONLY in the headline, for an A/B test: same picture, product, layout, colours and every other line. Pass `image`, and either `headlines` (your own, up to 10) or `count` (default 5, max 10) to have distinct angles written for you in the saved brand's voice (never inventing numbers, prices, ratings or claims the ad or brand does not state); `brief` steers what to test. The ad's text is read first (3 credits), then one image edit per headline; each output is proofread and flagged (textCheck) if the rendered words do not match, never silently re-rendered. The whole batch is priced before anything runs. Returns each headline, its angle and its image URL.
