- Buyer agents create tokens and send them to seller services to prove the buyer’s identity (kya and kya+pay tokens) and / or make payment for goods, services, and / or tools (pay and kya+pay tokens).
- Each token is made by a specific buyer agent for a specific seller service.
- Seller services specify how they want to receive the tokens in their API spec. E.g. seller services could use a custom HTTP header, add them as an argument to request bodies, or specify something else.
