Built for every team

One gateway. Five ways to win.

Same product — different outcomes for engineering, finance, agencies, security, and ops.

For Engineering

Developers & platform teams

Ship fast without handing out the master key

Mint a virtual key per service, developer, or environment. Model allowlists, RPM limits, and expiry dates — without a secrets rotation fire drill.

Drop-in OpenAI & Anthropic SDK — change base_url + api_key only
Streaming, retries, and tool calls work unchanged
Revoke one key in one second across every gateway replica
Never commit sk-… again — leak a kc- key, kill just that key

For Finance & Ops

CFO, FP&A, and ops leads

Hard caps beat surprise invoices

Set monthly budgets per key before the spend happens. At 100%, requests stop with a clear 402 — not a five-figure bill at month-end.

Budget enforcement on every request, in milliseconds
Live spend vs cap on one screen
Automatic reset on the 1st (UTC) — predictable cycles
You still pay providers directly — KeyC never marks up tokens

For Agencies & consultancies

Client delivery & account teams

Every client gets their own key — and their own receipt

Ten clients on one OpenAI account used to mean one mystery invoice. Give each client a key, cap each budget, and read spend by key on the dashboard.

One virtual key per client or project
Live cost per key — ready for accounting handoff
Project ends? Set expiry — access dies automatically
Bill pass-through AI costs with proof, not spreadsheets

For Security & compliance

CISO, security engineers, GRC

Govern access without reading prompts

Real provider keys live encrypted in the vault. Virtual keys are hashed — shown once, never stored. We meter metadata only: tokens, model, latency, cost.

AES-256-GCM for provider keys; master key stays in your env
Full audit trail of key usage — no prompt content logged
Instant revocation propagates via Redis pub/sub
Built for teams that need control, not another data processor

Privacy model

Security-focused vault and compliance with KeyC

For DevOps & platform

SRE, platform, and on-call

Alerts at 80%. Blocks at 100%.

Budget thresholds hit Slack or email once — not as a pager storm. Gateway replicas stay hot; Postgres never sits on the request path.

Slack + email alerts on configurable thresholds
Cache-first auth — Redis and Postgres stay off the hot path when healthy
Redundant gateway replicas behind your edge
Health endpoint and enforcement you can put on-call
