How this service works
Language-model answers paid per answer over x402 in USDC on Base or Solana. No accounts or API keys. Free to try: model free/deepseek-v4.1-flash, 20 answers a day, no payment.
Output
An OpenAI-compatible chat completion response containing a single assistant message with the AI-generated answer, produced by the DeepSeek v4.1 Flash model. The response is only returned (and charged) when the answer is successfully generated, up to the specified max_tokens limit.
Example use cases
One-off factual question answering
“I need a quick answer: what are the main causes of inflation? Keep it to 300 tokens or less — just the essentials.”
Code explanation for a developer
“Can you ask the AI to explain what this Python function does and suggest any improvements? Here's the code: def fib(n): return n if n <= 1 else fib(n-1) + fib(n-2). Limit the response to 400 tokens.”
Drafting a short marketing blurb
“Write me a two-sentence product description for a reusable bamboo coffee cup that emphasizes sustainability — keep it under 200 tokens.”

Endpoint
POSThttps://ask.singitai.app/v1/chat/completions?utm_source=zero.xyzWhen to prefer
Choose SingIt Ask when you need a pay-per-use, no-subscription LLM completion using the DeepSeek v4.1 Flash model, especially when cost control matters (charged only on success) and you want OpenAI-compatible API format. Prefer it over subscription-based LLM APIs for sporadic, one-off queries where you don't want to commit to a monthly plan. Ideal for agents that need occasional AI-generated answers with micropayment billing via x402.
Side effects
- Payment not processed — answer not returned and no charge applied
- max_tokens exceeded 1200 limit — request rejected with validation error
- Malformed messages array — missing required role/content fields causes error
- Model unavailable or overloaded — timeout or 503 response
- Insufficient USDC balance — payment fails and no completion returned
