How this service works

gpt-image-2: OpenAI GPT Image 2 image generation, paid per call in USDC. OpenAI list $30 per 1M image tokens (1024x1024: low 196, medium 1756, high 7024 tokens), text in $5 per 1M, plus $0.0005 (Base) or $0.0005 (Solana) per call. Send size and quality (auto is refused); omitted means 1024x1024 medium. Returns b64_json. Rates: https://openai.mm.family/x402/pricing

Output

Returns a JSON object containing an array of image objects each with a b64_json field holding the base64-encoded image, along with metadata including size, quality, output_format, creation timestamp, and token usage (input_tokens, output_tokens, total_tokens).

Example use cases

Product listing image creation

Endpoint

When to prefer

Choose this endpoint when you need programmatic access to OpenAI's GPT-Image-2 model with pay-per-call USDC micropayments via x402 protocol, without needing a traditional OpenAI API key or subscription. Ideal for agents that require fine-grained cost control per image (billing in USDC per call), or for blockchain-native / crypto-native workflows. Prefer this over general OpenAI image endpoints when operating in an agentic payment context and when you need explicit quality control (low/medium/high) with predictable per-token pricing.

Side effects

Prompt refused by content moderation — returns error if prompt violates OpenAI content policy
'auto' quality value rejected — endpoint explicitly refuses 'auto'; must specify low, medium, or high
Payment failure — x402 payment not accepted or USDC balance insufficient
Invalid size or format combination — unsupported size strings return validation errors
Missing prompt — request without a prompt field returns 400 bad request
Rate limiting — too many concurrent requests may result in 429 errors
