A retry loop looks like traffic, not a bug
Nothing about a stuck agent looping on the same call trips a typical uptime or error-rate alert-it just looks busy.
By risk
The bill that shows up before the incident report does.
A stuck retry loop looks like normal traffic right up until the invoice arrives. A compromised key can turn your own gateway into someone else's compute. Cost incidents rarely trip a security alert-until you build one.
Why it matters
Cost incidents hide in plain sight
Compromised keys become someone else's compute
A leaked credential doesn't need to breach your data to cost you money-it just needs to make calls under your account.
Cost incidents rarely trip a security alert
Spend anomalies live in finance's dashboard, not security's, so nobody's watching for them in real time by default.
What Lineation does
A cost incident, handled like a security incident
Real-time spend-rate monitoring
Every agent and key has a baseline spend rate; deviation is visible immediately, not at month end.
Hard caps at the gateway
Limits are enforced before a call completes, not after it's already billed.
Automatic circuit-breaker
Anomalous call volume trips a breaker automatically, stopping the bleeding without waiting for a human.
On-call alerting
Anomalies route straight to on-call with the exact agent, key, and workflow responsible.
How it works
Five steps from anomaly to contained
Baseline spend rate
Normal velocity per agent and per provider becomes the reference point.
Detect anomalous velocity
Loops, retries, and credential misuse show up as deviation from baseline immediately.
Trip the circuit-breaker
The next call is stopped before it executes, not after it's billed.
Alert on-call
The exact agent, key, and workflow are surfaced immediately, not buried in a monthly report.
Review and reset
Limits are restored manually once root cause is confirmed, avoiding a silent repeat.
FAQ
Common questions
How is this different from a provider's billing alert?
Provider alerts fire after a threshold is crossed on aggregate spend. Gateway-level monitoring detects anomalous velocity per agent in real time and can trip a breaker before the next call.
Can a circuit-breaker take down a legitimate workflow?
Thresholds are calibrated against each agent's own baseline spend rate, so normal high-volume workflows aren't flagged.
Does this catch a compromised API key used outside our systems?
Yes-traffic that doesn't match the agent's normal pattern, volume, or origin is flagged as an anomaly and can trigger an automatic cap.
How quickly can spend be capped?
The circuit-breaker evaluates at the gateway before each call completes, so containment happens in the request path itself.
Do caps apply per agent, team, or org-wide?
Caps are configurable at any of those levels, so a runaway agent can be stopped without capping everyone else.
What happens after a circuit-breaker trips?
On-call is alerted with the exact agent, key, and workflow. Limits reset manually once root cause is confirmed.
