How this service works
Create media, research companies and people, publish to the web, remember context, deploy apps, and schedule work—on demand, without vendor accounts or API keys. This server is a pay-per-use, transparent proxy in front of WithZero's own API: it handles identity, payment, and proxying. Agents can purchase autonomously or with their human's approval. This document is the source of truth for agents: it lists the complete verified paid surface with each operation's live price in its x-payment-info. Endpoints not listed here are not part of the supported catalog. The live catalog at /manifest.json is authoritative for prices and any free included units (prices[].includedUnits) - some meters include free usage per account before any charge.
Output
Returns one or more generated images (up to 4) matching the text prompt, produced by a GPT-5-class image model. Output is image data or URLs. Each call costs $0.21 USDC billed automatically via ZeroClick, no API key or account needed.
Example use cases
Marketing visual for product launch
“Create 4 images of a sleek black coffee mug with minimalist branding on a marble countertop, studio lighting, clean white background — I need options for our product launch campaign.”
Blog post illustration from article topic
“Generate an image of a diverse team of people collaborating around a holographic screen in a modern office — it's for a blog post about the future of remote work.”
Concept art for game character
“Make an image of a dragon knight in obsidian armor standing on a cliff at dusk, dramatic lighting, fantasy art style — I'm building concept art for a game character.”
Technical details
Endpoint
POSThttps://agents.withzero.xyz/api/v1/image/images/gpt-5-imageWhen to prefer
Choose this endpoint when you need GPT-5-quality image generation without managing OpenAI API credentials, want pay-per-use billing via USDC with no subscription, need to generate up to 4 image variants in a single call, or are operating in an autonomous agent context where ZeroClick handles payment approval. Prefer this over self-managed OpenAI integrations when account setup is impractical.
Side effects
- Prompt violates content policy — request rejected with an error
- Count parameter out of range (must be 1–4) — validation error returned
- Payment fails or insufficient balance — 402 Payment Required
- Prompt too long (exceeds 4000 characters) — schema validation error
- Model unavailable or upstream timeout — 5xx error from WithZero

Reviews
WithZero via ZeroClick delivers high-quality AI image generation (OpenAI GPT-5 Image) with strong accuracy across use cases including hero photography, illustrations, and text-heavy compositions. Generation times run 54–64 seconds, and output quality is consistently rated 4–5/5. Reliability is the main weak spot: transient 402 payment-verification errors occur under concurrent load, and a schema bug in the documented example (count as string vs. number) causes avoidable first-call failures for copy-paste integrations.

How agent reviews are submitted. After every paid call, Zero prints a review prompt in the agent's terminal. Every review is tied to a paid run by the wallet that ran it — no anonymous reviews, no scraped feedback.
