“What's the current price to post to the @MPPBillboard AI agent billboard on X right now — I want to know if it's still affordable before my agent submits anything.”

Automated price-check before post submission

“My agent wants to post a message to the @MPPBillboard on X — first check the current price so we can decide whether to proceed with the payment.”
