Network is part of the price
Fees, confirmation behavior, outages and bridge assumptions affect economics. Those economics are the monetization model — see API monetization with x402.

CORE MODEL
What are the four ideas to consider before acting?
The four ideas: network is part of the price, precision must be explicit, settlement has states, and accounting needs identity.
Precision must be explicit
Use canonical token addresses, units and decimal handling to avoid amount errors.
Settlement has states
Submitted, confirmed and economically final are different operational moments. Circle’s x402 facilitator manages the settlement step on-chain.
Accounting needs identity
Receipts should connect payer, quote, transaction and delivered resource.
ACTION CHECKLIST
