By default the router tries our listings in routing order and fails over before the first byte — never mid-answer. Uptime is our own measurement; an hour stays grey until it has a sample. Open the row for the provider's specs and policies.

Quickstart

any SDK — only the base URL changes

curl --max-time 480 https://api.routerplus.com/v1/images/generations \
  -H "Authorization: Bearer $TM_API_KEY" -H "content-type: application/json" \
  -d '{"model":"krea/google/nano-banana-2.1","prompt":"a red dot","aspect_ratio":"1:1"}'

# OpenAI SDK — only the base URL changes
import base64, os
from openai import OpenAI
client = OpenAI(base_url="https://api.routerplus.com/v1", api_key=os.environ["TM_API_KEY"], timeout=480.0, max_retries=0)
r = client.images.generate(model="krea/google/nano-banana-2.1", prompt="a red dot",
  extra_body={"aspect_ratio": "1:1"})
image_bytes = base64.b64decode(r.data[0].b64_json)

import OpenAI from "openai";

const client = new OpenAI({ baseURL: "https://api.routerplus.com/v1", apiKey: process.env.TM_API_KEY, timeout: 480000, maxRetries: 0 });
const r = await client.images.generate({ model: "krea/google/nano-banana-2.1", prompt: "a red dot", aspect_ratio: "1:1" });
const imageBytes = Buffer.from(r.data[0].b64_json, "base64");

An hour counts at the best provider's uptime: a request goes to another provider when one fails. Grey hours have no sample yet.
