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. Exact payers are instead charged that ceiling flat, with no metering.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
