SingIt Ask
SingIt Ask: Ask a language model without an API key: any model listed at GET /v1/models (Claude, GPT, Gemini, Grok, DeepSeek, Qwen and more; default deepseek-v4.1-flash). OpenAI chat-completions request. Pays actual token cost + 30% + a settlement fee (0.001 USDC on Base, 0.002 on Solana), up to a ceiling that follows the model's price; nothing is charged without an answer.
