VCAP-AP2 Binding
If the AP2 Protocol is how agents agree and initiate payment intent, this binding is how those intents acquire concrete escrow and capture rules under VCAP — without hand-waving the gaps.
Definition
What it is
An IETF Internet-Draft that bridges AP2 flows to VCAP escrow, release conditions, and capture behavior.
Who it's for
Implementers wiring marketplace negotiation to settlement backends.
When to use
- You implement AP2 and need precise settlement mapping
- You are debugging mismatches between negotiation states and escrow states
- You want one chartable path from “accepted” to “funds released”
Numbers and limits
- Problem solved
- Keeps AP2 and VCAP aligned so releases are predictable
- Typical flow
- Intent → hold → verified delivery → capture
- Spec pairing
