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 https://api.routerplus.com/v1/images/generations \
  -H "Authorization: Bearer $TM_API_KEY" -H "content-type: application/json" \
  -d '{"model":"seedream-5.0-pro","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"])
r = client.images.generate(model="seedream-5.0-pro", prompt="a red dot",
  extra_body={"aspect_ratio": "1:1"})
png = 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 });
const r = await client.images.generate({ model: "seedream-5.0-pro", prompt: "a red dot", aspect_ratio: "1:1" });
const png = 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.
