Why developers choose us

Why developers pick us

One API, every model

Switch between OpenAI models — gpt-5, gpt-5-mini, o-series — all through a single endpoint. No SDK juggling, no auth chaos. More providers next phase.

Payment flexibility built in

Bank transfer or USDT (BSC/TRON) — pick what works for you. No minimums, no commitments, no surprises.

One line of code to start

Already using OpenAI SDK? Change the base_url. That's it. Your existing code keeps working—now with multi-provider routing.

Live models

Live pricing across all models.

Real prices, real latency. Updated continuously.

Routing engine

Smart routing, automatic fallback.

Your request finds the best path. If one provider hiccups, we fail over instantly.

  • Automatic fallback.When a provider returns 429 or 5xx, we transparently retry on your next-best model.
  • Cost-aware routing.Pick the cheapest model that meets your quality bar — set a ceiling and we stay under it.
  • Latency caps.Bail out to a faster provider when p95 crosses your SLO.
  • Timeout retries.Network errors and timeouts retry with exponential backoff before surfacing to you.
ruleProvider failover
when upstream.status in (429, 5xx)
then retry on next model in chain
ruleCost ceiling
when model.type == 'chat'
then prefer model where $/1M ≤ $2.00
ruleLatency SLO
when p95(latency) > 2000ms
then route to faster family
ruleTransient errors
when timeout || network_error
then retry up to 3× with backoff

The request path

From your app to the right model in one hop.

Median overhead: under 15ms.

step 1
Client request

Your app posts to api.zionrouter.com with a Bearer key.

step 2
Router

Auth, rate limit, and model resolution in under 2ms.

step 3
Policy

Routing rules pick the provider and apply budget caps.

step 4
Upstream call

Request is forwarded to the chosen provider over a warm connection.

step 5
Streamed response

Tokens stream back to your client; usage is logged to your dashboard.

p95 router overhead: 12ms — added to upstream provider latency.

Drop-in SDK

Five seconds to switch.

If you're using OpenAI's SDK, here's all you change:

from openai import OpenAI

client = OpenAI(
    api_key="zr-...",
    base_url="https://api.zionrouter.com/v1",
)

resp = client.chat.completions.create(
    model="gpt-5-mini",
    messages=[{"role": "user", "content": "Hello"}],
)
print(resp.choices[0].message.content)
100% compatible with openai-python & openai-nodebase_url: https://api.zionrouter.com/v1
