Higgsfield AI Image Generation Skill

Overview

Generate images using Higgsfield AI's web UI (Nano Banana Pro model) via Playwright browser automation. The Higgsfield API credits are separate from web UI credits, so we use browser automation to leverage the user's web subscription.

Architecture

• API Endpoint: POST https://fnf.higgsfield.ai/jobs/nano-banana-2
• Auth: Cookie-based session from scripts/.hf-cookies.json
• Image CDN: URLs contain higgs.ai or d8j0ntlcm91z4.cloudfront.net
• Aspect Ratio: Uses UI default (3:4 at 1K); CSS object-fit: cover handles display ratios
• Format: Higgsfield returns WebP; script converts to JPEG via Pillow
