Practical next steps
- Read one primary vendor or standards document this week—not only summaries.
- Write a one-page policy for any agent that can move money (spend controls).
- Separate announced features from what your account can enable today.
- Log experiments; do not fund unconstrained wallets.
- Revisit this page when product status changes—timestamps matter in payments infrastructure.

How to compare providers without marketing fog
Score each option 1–5 on:
- Fee transparency (effective rate at your volume)

Run a sandbox purchase and a refund before production. Spreadsheet beats slide decks.
