What it does

Everything between your app and the model.

The request path

Watch a request move through the gateway.

Authentication, paywall, rate limits, routing and BYOK decryption — every guardrail on the way to the model, with automatic fallback when a provider fails.

One call in. Every guardrail. The right model out.

Getting started

Live in four steps.

1

Add your provider keys

Paste the OpenAI, Anthropic or Gemini keys you already have. They are envelope-encrypted the instant they land.

2

Create a gateway key

Generate a vk_live_… key for your app. Your provider keys never leave VaultAPI.

3

Point one base URL

Change your SDK's base URL. Every request now flows through auth, routing, fallbacks and logging — no rewrites.

4

Watch and tune

Read per-request logs and spend, then add routing rules to move cheap-enough prompts to cheaper models.

BYOK security

Your keys. Encrypted before they ever rest.

VaultAPI is bring-your-own-key by design. Every provider secret is envelope-encrypted the moment it arrives and decrypted in memory only for the instant a request needs it — so a database leak reveals nothing.

01

You paste a provider key

master key

sk-… never leaves the request body in plaintext — it is wrapped the moment it lands.

02

Envelope-encrypted at rest

wrapped DEK

A per-key DEK is sealed with AES-256-GCM under a versioned master key.

03

Decrypted in memory only

provider key

Unwrapped for the exact instant a request needs it — never logged, never written to disk.
