How this service works

Keyless GPT-5 Mini chat completions for $0.005 USDC per call through x402.

Output

Returns a standard OpenAI-compatible chat completion JSON object containing the assistant's reply message, finish reason (e.g. 'stop'), token usage breakdown (prompt, completion, total), a completion ID, model name, and creation timestamp.

Example use cases

Keyless LLM for autonomous agent

“I need my agent to answer user questions using GPT-5 Mini without managing API keys — just pay $0.005 USDC per call via x402. Send it the user's question as a user message and return the assistant's reply.”

On-demand content summarization

“Summarize this support ticket in 2 sentences using GPT-5 Mini: 'Customer reports that the checkout button on mobile doesn't respond after tapping. Reproducible on iOS Safari 17. No error shown.' — pay per call, no account needed.”

Automated Q&A for a chatbot pipeline

“Build a pipeline that takes a system prompt saying 'You are a helpful cooking assistant' and a user question like 'What can I make with chicken, lemon, and capers?', then calls GPT-5 Mini for a reply — limit the response to 200 tokens and pay via x402 micropayment.”

When to prefer

Choose this endpoint when you need GPT-5 Mini chat completions without managing API keys or subscriptions, paying only $0.005 USDC per call via the x402 micropayment protocol. It is ideal for autonomous agents, serverless pipelines, or low-volume use cases where per-call billing is preferable to monthly commitments. Prefer this over traditional OpenAI API access when operating in trustless or keyless environments where USDC micropayments are the payment primitive.

Side effects

Payment failure: x402 payment not included or USDC balance insufficient — returns 402 Payment Required
Invalid model: model field not set to 'gpt-5-mini' — returns 400 validation error
Message limit exceeded: more than 24 messages or content over 4000 chars — returns 400 validation error
Token limit exceeded: max_tokens or max_completion_tokens above 512 — returns 400 validation error
Empty messages array: minItems:1 not satisfied — returns 400 validation error
Service unavailability: inference backend unreachable — returns 502 or 503
