How this service works
OpenAI-compatible chat completion, priced by counted input tokens + max output tokens at per-model rates
Output
Returns an OpenAI-compatible chat completion JSON object containing a unique completion ID, the model used, the assistant's reply message, the finish reason (e.g. 'stop'), and the choice index. The content field holds the generated text response.
Example use cases
One-off coding help with GPT-6
“Use MapleAI's GPT-6 Sol model to answer this for me — system: 'You are an expert software engineer', user: 'Explain the difference between async/await and promises in JavaScript with examples' — cap the reply at 800 tokens.”
Automated content drafting agent
“I'm building an agent that drafts product descriptions. Using MapleAI's GPT-5.6 Terra model, send: system: 'You are a marketing copywriter', user: 'Write a 3-sentence product description for a noise-cancelling travel pillow' — limit to 200 tokens.”
Comparing GPT model tiers on same prompt
“Send the same message to MapleAI's GPT-5.6 Sol and GPT-6 Luna models — system: 'You are a summarizer', user: 'Summarize the causes of World War I in 5 bullet points' — max 300 tokens each — so I can compare the outputs.”
Technical details
Endpoint
POSThttps://base.mapleai.shop/api/v1/chat/completions?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need OpenAI-compatible chat completions with no monthly subscription, paying only $0.01 USDC per call via the x402 protocol on Base. Ideal for infrequent or bursty workloads, agent pipelines needing crypto-native billing, or developers wanting to experiment with GPT-5.6 and GPT-6 model tiers without committing to a plan. Prefer over standard OpenAI API when you need USDC micropayment billing or want to avoid API key subscription overhead.
Side effects
- Payment failure: x402 payment not processed or insufficient USDC balance — request rejected before completion
- Invalid model ID: model string not found in /v1/models — returns error response
- Malformed messages array: missing required 'role' or 'content' fields — validation error
- max_tokens too low for the prompt context — truncated or empty response
- Rate limiting or capacity issues on MapleAI infrastructure — 503 or timeout
- Network failure on Base blockchain payment settlement — request not fulfilled
