unprobed
Use this when you need an answer from a frontier AI model without an account or an API key: Claude (Opus, Fable, Sonnet, Haiku), GPT-6 or Grok, one call. Price: $0.005 in USDC on Base or Solana, or $0.02 in USDG or $SWOGE on Robinhood Chain (tool price + settlement cost, minimum $0.02).
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
