Agents chain tool calls faster than any human review loop. If a request can't prove itself at the boundary, your agent framework is running on trust.

An autonomous agent doesn't browse your API — it fires chained tool calls, dozens per minute, each one decided by a model in the previous step. Traditional controls assume a human session: log in once, hold a token, act at human speed.
Agents break every part of that assumption. There is no session to establish, no human to challenge, and no time for out-of-band approval.
The only checkpoint that can keep up is the request itself. Trustplane sits in front of the API and evaluates a cryptographic proof on every single call — who the caller is, what it's allowed to do, and whether this exact request was authorized. Valid once, verified in milliseconds, logged for audit.
When an agent oversteps — a hallucinated endpoint, an out-of-scope action — the boundary refuses the request. Not the session, not the deployment. That one request.
Every request proves itself — no keys, anywhere.
Put the boundary in front of one API and measure it yourself.
