AI agents use purchase_single_patent to commit financial operations through Mirelia-Structured-Data-Marketplace — usually the final step of a payment, billing, or trading workflow. A call moves real money.

The sibling tool 'verify_crypto_payment_and_deliver' further confirms this is part of a payment flow.
