OpenRouter

OpenRouter is a unified gateway to 200+ models from OpenAI, Anthropic, Google, Meta, Mistral, DeepSeek, and most open-weight providers. One OpenAI-compatible endpoint, automatic upstream failover, and a single bill — Vendo handles auth and settlement against your balance per call.

Auth modes

Environment variables

These are the env vars Vendo injects into your deployment at boot when this integration is bound. Source values are resolved by resolveConnectionEnvVars in packages/integrations/lib/ from the connection record (credential, metadata) and deployment context (proxy URL, Vendo-issued API key).

Reading the credential at runtime

Vendo writes OPENROUTER_API_KEY (and any companion vars above) into your deployment's environment at boot — the official OpenRouter SDK auto-discovers it, so most code just instantiates the client with no extra wiring. vendo.token(slug) is the resolution-chain-aware alternative that reads the same value in Vendo mode and falls back to whatever you set in OSS mode; use whichever fits your style. See Two modes for the full resolution chain.

Proxy endpoint

Calls to OpenRouter are brokered through Vendo's proxy at:

https://openrouter-proxy.vendo.run

Point the official OpenRouter SDK at this base URL; Vendo authenticates, meters per call, and forwards upstream. Your code never sees the upstream credential.

Quickstart

import vendo

# Access every major LLM through one API. Routed via Vendo's pool — billed against your Vendo balance, no separate signup needed.
token = vendo.token("openrouter")

# Use `token` wherever you would have used the provider's API key —
# pass it to the official SDK or set it as the env var the SDK reads.
print(token)

import { Vendo } from "@vendodev/sdk";

const vendo = new Vendo();
// Access every major LLM through one API. Routed via Vendo's pool — billed against your Vendo balance, no separate signup needed.
const openrouterToken = await vendo.token("openrouter");

// Use `openrouterToken` wherever you would have used the provider's API
// key — pass it to the official SDK or read it as the env var the SDK expects.
console.log(openrouterToken);

import VendoSDK

let vendo = Vendo()
// Access every major LLM through one API. Routed via Vendo's pool — billed against your Vendo balance, no separate signup needed.
let token = try await vendo.token("openrouter")

// Use `token` wherever you would have used the provider's API key.
print(token)
