{"ok":true,"host":"api.imgzen.dev","status":"ready","manifest":{"positioning":"ImgZen is a pay-per-request image generation host serving agents that need to produce images from text prompts without managing model infrastructure. It exposes multiple model tiers under a consistent API surface, allowing agents to trade off cost against capability. The host is distinct in its native x402 micropayment integration on Base, making it suitable for autonomous agents that handle on-chain payments.","host_overview":"api.imgzen.dev is a text-to-image generation API offering four model endpoints — NanoBanana, NanoBanana 2, Nano Banana Pro, and GPT-Image-2 — each returning a CDN-hosted image URL. All endpoints are billed per-request via x402 payments in USDC on Base (ranging from ~$0.02 to $0.20). No image editing, inpainting, or video generation is supported.","routing_guidance":"Use api.imgzen.dev when an agent needs to generate new images from text prompts and can pay per-request in USDC on Base via x402. Choose generate-image-nano-banana for the lowest cost (~$0.02), generate-image-nano-banana-2 for mid-tier quality ($0.10), generate-nano-banana-pro-image for the highest NanoBanana quality ($0.20), or generate-image-gpt-image-2 when GPT-Image-2 output or reference-image grounding is required. Do not use this host for image editing, inpainting, upscaling, or video generation — those capabilities are absent entirely. Do not use it for batch generation workflows that cannot handle per-request x402 payment flows. If free or subscription-based image generation is needed, this host is not appropriate.","capability_clusters":[{"skill_names":["generate-image-nano-banana","generate-image-nano-banana-2","generate-nano-banana-pro-image","generate-image-gpt-image-2"],"cluster_name":"Text-to-Image Generation","cluster_summary":"All four skills generate new images from text prompts and return CDN-hosted URLs.
