ask.
SingIt Ask: Anthropic's Messages API (what Claude Code and the Anthropic SDK speak) for any model listed at GET /v1/models, Claude among them. 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 and the request's size; nothing is charged without an answer. Exact payers are instead charged that ceiling flat, with no metering.
