Change the route.
Keep the request.

Two changes to get started.

Anyroute accepts the familiar chat-completions request. Replace the base URL and key; requests, streaming, tools, provider preferences and usage fields work unchanged. Keys are self-custodial: POST /api/v1/keys (no account) returns a key and the hash to deposit USDG to.

// Change two lines: the base URL and the key.
const client = new OpenAI({
  baseURL: process.env.ANYROUTE_BASE_URL, // "<your router>/api/v1"
  apiKey: process.env.ANYROUTE_API_KEY,   // "sk-ar-v1-…"
});

const generation = await client.chat.completions.create({
  model: "meta-llama/llama-3.3-70b-instruct",
  messages: [{ role: "user", content: "Hello, Anyroute." }],
});

Make the route explicit.

The provider object supports order, allow_fallbacks, only, ignore, data_collection, zdr, quantizations, sort, max_price, require_parameters and preferred latency or throughput. Model suffixes :nitro, :floor, :free and :private work too. models[] lists fallback models. The private flag is an Anyroute extension: it selects only providers with a fresh TEE attestation. By default providers are weighted by 1/price² × 30-day uptime × canary quality, and a provider with two failures in 30 seconds is skipped.

  "model": "meta-llama/llama-3.3-70b-instruct",
  "models": [
    "qwen/qwen3-32b"
  ],
  "messages": [
    {
      "role": "user",

}

One settlement unit. More ways to pay.

Providers are paid their list price minus a 2% settlement fee; creator royalties appear as a separate cost line. Stock Token swaps are slippage-bounded and never exceed your daily cap. Prices are per token and come from each provider.

The response is only the beginning.

Every generation returns normalized usage and an Ed25519-signed receipt with hashes of the request and response (never their content). Receipts are anchored in hourly merkle batches on Robinhood Chain, and the signing keys are published on-chain. Signed is not the same as anchored: the dashboard and /api/v1/receipts/verify report each separately.

Endpoint map

Limits and guarantees.

Each call holds its worst-case cost before routing and settles the metered usage after, so a key never goes past its balance or budget. Keys have a per-minute request limit, and optional token-per-minute limits; n and best_of are capped at 16. If every provider fails, nothing is charged. A cancelled stream is billed only for what was generated.

The router stores key hashes, balances and receipt metadata. It never stores prompts or responses; the optional response cache is encrypted, per-workspace and expires. Provider data policies are listed per provider.
