Agents are moving from chat to action
McKinsey reports 23% of surveyed organizations are scaling an agentic AI system somewhere in the enterprise, with another 39% experimenting. That creates a new control point: tool and payment decisions.
Global product wedge - agent spend control
Stop AI agents from paying the wrong tool.
Ontario Agent Payment Firewall is a pre-payment policy gate for AI agents, MCP tools, and x402-paid APIs. It verifies endpoint readiness, checks price/network/report evidence, and returns allow, review, or deny before a wallet signs.
Why this can become the global product, not just an x402 page
MCP makes tool access standard
Anthropic describes MCP as a standard for connecting AI assistants to the systems where data lives. Once tools are standardized, buyers need standardized policy gates.
Payments are becoming agent-readable
Google AP2 and Stripe ACP both point toward agents initiating commerce. Ontario should own the pre-payment firewall before the agent signs or delegates spend.
The API surface already exists

The business is not the free API alone. The business is implementation, policy design, monitoring, and evidence packs for teams that are about to let agents invoke tools or payments.

Managed policy monitor
$2,000/mo
Monitor report freshness, policy drift, payment metadata changes, and alert before agents continue spending.

Request the implementation packet
Send one agent workflow, MCP server, or paid API endpoint. Ontario will return a scope decision and, if useful, a fixed-price implementation packet.
Trust boundary
- Ontario does not sign wallet payloads for the user.
- Ontario does not guarantee endpoint safety, legal compliance, service quality, or future behavior.
- Ontario provides observable readiness evidence and policy output that agents, wallets, and humans can enforce.
- Private keys, seed phrases, and production wallet custody should never be sent to Ontario.
