Make AI spend
accountable.
P402 turns every AI request into an economic event with owner, workflow, model, provider, tokens, cost, budget, policy result, outcome, and evidence status. Private by default, metadata-only metering.
No prompt storage required. Metadata-only mode is available from the first event.
AI spend arrives too late.
Provider invoices show totals after usage happens. They do not show which customer, feature, workflow, department, employee, model, or retry caused the cost. P402 records that ownership when the event happens.

Built on an open standard
P402 implements Google Cloud's open Agent-to-Agent (A2A) protocol.
The quotes below are public statements by partners of the A2A standard about the protocol itself, not endorsements of P402. Source: Google Cloud A2A launch announcements.
"Ask-AI is excited to collaborate with Google on the A2A protocol, shaping the future of AI interoperability."
"A standardized protocol like A2A will help agents successfully discover, coordinate, and reason with one another to enable richer forms of delegation."
"We’re enabling Articul8's ModelMesh to treat A2A as a first-class citizen, enabling secure, seamless communication between intelligent agents."
"We look forward to enabling Box agents to work with Google Cloud’s agent ecosystem using A2A... empowering organizations to better automate workflows."
"A2A has the potential to help customers break down silos and securely enable AI agents to work together across systems, teams, and applications."
"As a pioneer in enterprise multi-agent systems, Cognizant is committed and actively pursuing agent interoperability as a critical requirement."
"The open A2A protocol ensures seamless, trusted collaboration—even in air-gapped environments—so that businesses can innovate at scale."
"We're excited to see Google Cloud introduce the A2A protocol to streamline the development of sophisticated agentic systems."
"Salesforce is leading with A2A standard support to extend our open platform, enabling AI agents to work together seamlessly."
"ServiceNow and Google Cloud are collaborating to set a new industry standard for agent-to-agent interoperability."
"Establishing an industry standard for seamless agent-to-agent communication is a significant step towards a future in which AI agents and humans collaborate."
"Combining MongoDB with A2A lets businesses unlock new possibilities across industries to redefine the future of AI applications."
"PayPal supports Google Cloud’s A2A protocol, which represents a new way for developers and merchants to create next-generation commerce experiences."
A distribution loop tied to discovery.
Bazaar is the discovery layer for payable endpoints. Router adds runtime signals so buyers pick endpoints using real health and policy outcomes.
