Works with every model — bring your keys, or let us run it

Use any AI model. Don't pay for the ones that break.

The reliability & accountability layer for your AI spend. We catch failures, show you what they cost, and make sure you don't pay for them. Bring your own keys, or let us run the whole thing.

Core capabilities

Everything you'd expect — plus the part that's missing

One API for every major model, automatic failover, a unified usage view, and live cost, latency, and health decisions. The difference: every failed call is measured, priced, and surfaced in a monthly loss report.

One API, every major model

OpenAI, Anthropic, Google, and open models — all through a single unified endpoint.

Automatic failover

When a provider is down or rate-limited, requests go to the next healthy option automatically, in real time.

One usage view

Usage tracking and a single activity statement across all providers, no matter how many you use simultaneously.

Smart model selection

Choose by cost, latency, and live provider health so every request lands on the best available option.

Convenience is table stakes. Dashboards show activity. Defendr shows what broke, what it cost, and what you can recover.

Two ways in

Bring your own keys, or let us run it.

Either way you get one API, automatic failover, and the monthly loss report from day one. The difference is how far we take accountability.

Mode 1 · Start here

Bring your own keys

Platform fee

Parity pricing

Keep your own provider accounts and pay providers directly. Our platform fee is on par with any model router — so switching is low-friction. Your keys, your provider bill, your data.

  • One API, every major model, automatic failover
  • Monthly loss report — every broken call logged, categorized, and priced so you see exactly what failures cost you
  • Audit trail, drift watch, and billing anomaly flags included
Mode 2 · The upgrade

Let us run it

Managed

Prepaid

Use our managed accounts — prepay us, and we handle the provider relationships. When calls break, we credit you back. "Don't pay for bad calls" becomes fully real: the losses the report identified are recoverable.

  • Everything in BYOK mode, plus a real failure cushion
  • Credits back on broken calls — recover what the loss report showed you were losing
  • No separate provider accounts to manage — one prepaid relationship covers everything

The reliability layer

The part that's been missing

Getting calls to a model is table stakes. Defendr catches failures — measuring them, pricing them, and showing you exactly what they're costing you.

Monthly loss report

We instrument every call and send you a monthly breakdown — timeouts, empty output, hard refusals, and billing anomalies, each categorized and priced. You see exactly what failures are costing you, not just that they happened.

We make spend verifiable

We flag billing anomalies, redundant calls, and cheaper-model opportunities — and share the resulting savings with you. Your bill becomes verifiable.

A clean audit trail

A tamper-proof record of every call — inputs, outputs, latency, tokens — so compliance reviews and auditors have the data they need, already organized.

Drift watch

We flag when a provider silently degrades or swaps a model, measured against a fixed reference benchmark. You find out immediately — not when a prompt stops working in production.

Your keys, your data — built with security and compliance in mind. SOC 2 is on the roadmap.

How it works

Plug in, see what's breaking, and stop paying for it.

Bring your own provider API keys — you pay providers directly, and we sit in path. Or let us run the whole thing, with nothing for you to set up.

1

Start with your own keys

Bring your provider API keys and continue paying providers directly. Start with the same spend pattern you already know: no new accounts, no lock-in, no new token pricing model to learn.

2

See what failures cost you

We instrument every call in-path and send a monthly loss report — every timeout, empty response, and billing anomaly logged, categorized, and priced, so you see exactly what failures cost you.

3

Or let us run it — and get it back

Move to Managed, prepay us, and use our provider accounts — then we credit you back on broken calls. The report showed what you were losing; the cushion helps you recover it.

Aligned incentives

A partnership, not a tax

Basic model access gives you convenience. We add visibility, reliability, and a path to real loss recovery.

We make money when your AI works — we share the savings we find you, and in Managed we credit you back when it breaks. Our incentive is your reliability, not your token count.

Capability

One API, every model

Both — one API to every model, with parity platform pricing.

Automatic failover

Both. We move around failures in real time.

Monthly loss report

Us only — either way. Every broken call logged, categorized, and priced.

Failure cushion

Us only — Managed mode. We credit you back on broken calls.

Tamper-proof audit trail & drift watch

Us only — either way. A verifiable record of every call, and an early warning when the model quietly changes behind its version label.

FAQ

Questions, answered

Which models and providers can I use?
OpenAI, Anthropic, Google, and open models — all through one API. Add or switch models without new accounts or new code.
Do I have to change my code?
No. We sit in path — point your existing SDK or HTTP calls at us and keep the request format you already use. Bring your own keys, or let us run it.
What counts as a “broken call”?
Provider downtime and timeouts, empty or truncated output, invalid or failed structured output, refusals of legitimate requests, and billing or cache anomalies. Each one is detected, categorized, and priced on your monthly loss report.
Isn’t this just model access with dashboards?
You get the familiar basics — every model, automatic failover, one usage view, parity pricing. The difference is what happens when a call fails: we catch it, show you what it cost, and (in Managed) credit it back.
How do credits work in Managed?
In Managed, credits are bounded service credits on broken calls. In BYOK, you keep paying providers directly; the monthly loss report shows what failed and what it cost.
Is my data secure?
Your keys, your data. We build with security and compliance in mind, and a tamper-proof audit trail of every call is included. SOC 2 is on the roadmap.

What we're building

The reliability & accountability layer for AI spend.

Bring your own keys to see and price failures from day one. Move to Managed when you're ready to get credits back on broken calls.
