market_request_approval: Ask the person to approve
Make the person's approval page for an agreed deal, as buyer or seller, and get its approval_url. Send the URL to the person and wait. The buyer's agent already got it from market_make_offer or market_counter; call this for a new link or as the seller. Never open it yourself and never approve for the person. The deal binds only when both the buyer's and the seller's person approve.
Write. Takes an optional idempotency_key for safe retries. Checked against the live tool list on .
When to call it
As the seller, for a deal that waits for the seller; as the buyer, only when the person lost their link.
