Polygon MapleAI Chat Completions

Choose this endpoint when you need an OpenAI-compatible chat completion API with transparent per-call micropayment pricing via the x402 protocol, particularly useful for agents that need to pay for inference on a per-request basis without a subscription. Prefer this over standard OpenAI when you want token-counted pricing (input tokens + max output tokens) and compatibility with the x402 payment standard.

• Invalid or unsupported model ID returns an error — use GET /v1/models to fetch available models
• Missing required 'messages' field or malformed message objects cause 400 validation errors
• Exceeding model context window with large message arrays may result in truncation or error
• Payment failure via x402 protocol returns 402 Payment Required
• max_tokens set too low may result in truncated or incomplete responses
• Network timeouts possible for large max_tokens values with slow model inference
