The AI gateway market is booming. Bifrost, LiteLLM, Portkey, and others are racing to solve the same problem: how do you efficiently route LLM calls across multiple providers?
It's a real problem. When you're building AI applications, you don't want to be locked into a single provider. You want failover when OpenAI goes down. You want load balancing across API keys. You want semantic caching to reduce costs.
These gateways solve that beautifully. They're fast, reliable, and well-engineered.
But they solve the wrong problem for the agent economy.
The Routing Mindset
Routing gateways think about the world in terms of requests:
- Which provider should handle this request?
- How do we minimize latency?
- How do we maximize uptime?
- How do we cache similar requests?
These are infrastructure questions. They're about reliability and performance. And they assume a human is ultimately in control — making decisions about which applications to build, which APIs to call, and how much to spend.
The Agent Reality
Agents don't work that way.
An agent with access to an MCP tool server can decide — autonomously — to make thousands of API calls. It can spawn sub-agents, each with their own tool access. It can run overnight while you sleep.
The questions that matter in this world are different:
- How much is this agent allowed to spend?
- Which tools can it use, and at what cost?
- When should it stop — even if the task isn't complete?
- Who pays when the bill arrives?
These aren't routing questions. They're governance questions.
The Gap in the Stack
Here's the security stack most enterprises have today:
Routing gateways live in the infrastructure layer. They make sure requests get to the right place efficiently. But they don't answer the economic question.
That's the gap. And it's the gap that will cause six-figure surprises when agents start running autonomously at scale.
What Governance Looks Like
Economic governance for AI agents isn't just "budget tracking." It's enforcement:
Hard Budget Caps
When an agent hits its budget, requests are blocked. Not logged. Not alerted. Blocked. The CFO knows exactly what will be spent — not what was spent.
Per-Tool Cost Attribution
In MCP, agents call tools by name. Governance means knowing that Agent X spent $47 on the search_database tool and $12 on send_email. Not just "Agent X made 1,000 requests."
Delegation Without Escalation
When Agent A spawns Agent B, it should be able to give B a subset of its budget — not the master key. Macaroon-based credentials enable this; API keys don't.
Routing + Governance
This isn't an either/or situation. Routing gateways and economic gateways solve different problems. You might use both:
The economic gateway enforces budgets and tracks attribution. The routing gateway optimizes which provider handles each call. Different layers, different concerns.
The Question to Ask
When evaluating your AI infrastructure, ask this:
"If my agent makes 10,000 calls tonight while I'm asleep, who decides when it stops?"
If the answer is "when it finishes the task" or "when the API rate limits kick in," you have a routing gateway.
If the answer is "when it hits its $50 budget cap," you have governance.
The agent economy needs both. But right now, almost everyone has routing. Almost no one has governance.
That's the gap we're building SatGate to fill.
