}Prepare a guest per-call purchase: returns the authoritative price split, payment_id, purchase_ticket, reissued commerce_scope, and payment_plan. Pay by sending payment_plan.calls (to/value/data verbatim) from the buyer wallet as ONE atomic batch transaction on Base Mainnet — the platform call's data carries the required payment_id stamp; separate or re-encoded transfers are refused and not refunded.

}We read every tool's name, description and inputs the way the model will, looking for instructions hidden from you. A clean result means no warning signs, not a guarantee. Scanned Nov 6, 2026.
No readOnlyHint / destructiveHint annotations, so clients can't tell a read from a write without asking.
Fix: Add annotations to each tool, e.g. { readOnlyHint: true } for tools that only read.
