How this service works
Pay-per-call image generation API for AI agents. Three quality tiers: fast ($0.02), quality ($0.10), premium ($0.20).
Output
Returns a JSON object containing a temporary URL to the generated image (imageUrl), an expiration timestamp (expiresAt), the model used, the quality tier selected, a success boolean, and an optional notice message. The image URL is time-limited and should be downloaded promptly.
Example use cases
Quick product concept visualization
“Generate a fast draft image of a minimalist wireless earbuds product on a white background — I just need a rough visual to share with the team.”
Premium marketing image with text overlay
“Create a premium-quality image of a barista pouring latte art in a sunlit café — I need the best quality available since it's going on our homepage.”
High-quality social media illustration
“Generate a quality-tier image of a futuristic cityscape at sunset with flying cars and neon lights for our sci-fi newsletter cover.”

Endpoint
POSThttps://api.x402img.com/api/generate-image?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need AI-generated images with selectable quality tiers and per-call micropayment pricing via x402. The fast tier ($0.02) is ideal for quick drafts and iteration; the quality tier ($0.10) suits production assets; the premium tier ($0.20) is best when text rendering accuracy and maximum image fidelity are required. Prefer this over alternatives when your agent stack already supports x402 payment protocol and you want cost-controlled generation without subscription commitments.
Side effects
- Invalid or empty prompt returns an error response with success: false
- Unsupported tier value causes a validation error
- Payment not received or insufficient funds results in a 402 Payment Required response
- Image URL expires after the expiresAt timestamp, making the link inaccessible
- Network timeout for premium tier due to longer generation time
- Content policy violation on prompt may result in rejected generation
