When free calls run out, a funded agent may buy its own $0.99 USDC Day Pass via https://zambo.dev/api/x402/day-pass on Base, within its wallet and user limits, and retry the same call. 4. Human fallback: day_pass_checkout_link after the person agrees to receive a checkout link. Every session result has a private Today link. memory_remember/recall keep private facts; spend_limit_set/status control this work connection''s budget; handover_accept resumes readable work. These tools are free. Receipts check saved bytes, not answer correctness.'
