A marketing image API that matches how creative teams actually decide

Create a two-stage creative funnel

In stage one, the fast route produces genuinely different compositions rather than tiny variations. A strategist or designer selects the directions worth carrying forward. In stage two, the premium route refines only those candidates, followed by editing and final brand review.

This structure turns model tiers into a product decision. It also gives finance a clean unit model: draft cost per concept, promotion rate, premium cost per finalist, and total cost per approved asset. A single undifferentiated generate button hides all four.

Turn the campaign brief into structured prompt components

A useful brief separates non-negotiable message and brand rules from visual choices the model may explore. Store audience, channel, subject, required negative space, palette, prohibited motifs, and legal copy outside the free-form prompt. Your application then renders a controlled prompt from reviewed fields.

Do not ask the image model to be the final source of campaign text. Generate the visual field, then add typography with design tools or a deterministic rendering service. This improves accessibility, translation, legal review, and consistency across aspect ratios.

{
  "audience": "independent designers",
  "channel": "mobile landing page",
  "subject": "sculptural desk objects",
  "composition": "right-weighted with clear headline space",
  "palette": ["ink", "ivory", "cobalt"],
  "prohibited": ["logos", "embedded text", "weapons"]
}

Moderate for brand suitability in addition to platform safety

A platform classifier asks whether content is prohibited. A brand classifier asks whether content is appropriate for this audience, campaign, and region. The second layer may reject alcohol, political imagery, competitor marks, unsafe product use, or themes that are legal but off-brand.

Implement brand rules as a separate decision with its own labels. That keeps legal platform policy from becoming an unmaintainable bundle of customer preferences. The included moderation adapter can be extended to return both global-policy and tenant-policy categories.

• Global safety policy is never tenant-configurable
• Brand suitability can be stricter by tenant and campaign
• Every rejection needs a stable category for reporting
• Review regional and channel rules before publication

Connect generation data to the asset outcome

Counting generated images rewards waste. The useful funnel is generated, shortlisted, refined, edited, approved, published, and reused. Join RenderRoute request IDs to your asset system so provider cost and latency can be compared with acceptance and campaign performance.

Be careful about attributing downstream conversion to the model alone. Creative concept, copy, offer, media placement, and audience all interact. Use generation metadata to improve operations and controlled experiments to evaluate campaign impact.
