One API, major models
Use multiple providers and open models through one endpoint without rebuilding every call path.
How it works
Point calls through Defendr, then get a report you can act on.
Defendr keeps your model access workflow, then adds the part teams usually lack: objective failure detection, monthly loss evidence, and clear remedy status by mode.
What you get
The router basics, plus measured failure evidence.
Automatic failover
Move eligible requests to a healthy option when availability or capacity signals say the first path failed.
Monthly loss report
See failed calls grouped by failure type, event count, estimated cost, evidence, and remedy status.
Billing integrity signals
Compare observable usage, cache, and charge fields so billing anomalies are visible instead of buried.
Dashboards show activity. Defendr shows which billed calls broke, what evidence supports the finding, and what happens next.
The process
Three steps from call to remedy.
Send model calls through one path
Keep your model choice while attaching request, route, schema, timing, usage, and response evidence to each event.
Measure what is observable
Passive in path checks catch structural failures; active probes handle drift and baselines; some questions are flagged only when ground truth is available.
Review loss and remedy status
The report shows what failed, what it cost, the evidence behind it, and whether it is report only or eligible for Managed service credit.
Category contrast
Routing is not accountability.
A model gateway can make access easier. Defendr is focused on the evidence layer after the call: what broke, what it cost, and what remedy status applies.
| Category | What it usually answers |
|---|---|
| Routers | Which model should receive this request? |
| Observability tools | What happened in the trace, evaluation, or prompt workflow? |
| Cost tools | Where did spend go across teams, providers, and models? |
| Governance tools | Did the output meet policy, workflow, and review requirements? |
| Defendr | Which billed calls broke, what objective evidence supports that, what did they cost, and what remedy status applies? |
