Drop-in

Change the base URL. Keep everything else.

Requests are passed through untouched — thinking, cache_control, tools, images, safety settings, streaming. No translation layer, no silently swapped models. Your official SDK just works.

import Anthropic from "@anthropic-ai/sdk";

const client = new Anthropic({
  baseURL: "https://lovelyrouter.com",
  apiKey: process.env.LOVELY_KEY,
});

const msg = await client.messages.create({
  model: "claude-sonnet-4.6",

  messages: [{ role: "user", content: "Hello, lovely." }],
});

Cache-aware sticky routing

Every conversation is fingerprinted and pinned to the upstream that served it, so cached prefixes are read at cache prices — not re-written on a different host.

Transparent channel groups

Official API, AWS Bedrock, Vertex, Azure, vendor-official China APIs. Bind a key to a group and it never leaves it. Every response names the channel that served it.

Metered to the token

Input, output, cache reads, cache writes and reasoning tokens — billed separately at published prices and reconciled against what the upstream reports.

Native SDKs, zero rewrites

Anthropic, OpenAI and Gemini dialects served natively. Parameters pass through verbatim; the model you ask for is the model you get.

Live latency & reliability

P95 time-to-first-token, tokens/sec, success rate, cache hit rate and error mix per group — for your traffic and on the public status page.

Automatic failover

Retryable upstream errors fail over within the same group before a single byte is streamed. A per-route circuit breaker keeps dead channels out of rotation.

Channels, not black boxes

You always know where it ran.
