Can I pay this address? First 5 free. After free-5, buy looks_20 pack ($0.20) → X-Agent-Pass; look $0.10 is optional one-shot. No inbox. After Base EIP-3009 exact (CDP/AgentKit; no Solana key) or optional Solana USDC, call with invoice_id until token. Pass the Base payment object from payMeterPassBase / sign_exact.payment_template after you fill signature ({ x402Version, payload:{ authorization, signature }, accepted }) — not a raw signature string. Repeat until the result includes token — that is X-Agent-Pass. Then meter_scan with pass_token. Optional signature (tx sig only). We never take keys. No human account.
