Prepaid creditsPrices next to OpenRouter's

Pay per unit. Not per month.

One OpenAI-compatible endpoint for 13 models from 9 providers.

Every price is shown per unit next to OpenRouter's public price, with the difference. Change the base URL and the key; the rest of your code stays the same.

https://api.azrouter.dev/v1

How a request travels

Your code, one base URL, every provider in the catalog.

Point an OpenAI SDK at api.azrouter.dev/v1. AZRouter checks the key and your credits, sends the call to the model's provider and debits the units it used.

Why AZRouter

Change two values. Keep your code.

One key for the catalog's providers, prices you can check per unit, and credits you top up before you spend them.

An OpenAI-compatible base URL

Point the official OpenAI SDK, or plain curl, at api.azrouter.dev/v1 with an sk-… key. Request and response formats stay OpenAI's.

client = OpenAI(
    base_url="https://api.azrouter.dev/v1",
    api_key=os.environ["AZROUTER_API_KEY"],
)

Per-unit prices next to OpenRouter's

Prepaid credits, no subscription

Top up US-dollar credits; each request debits its settled cost, rounded to the nearest $0.000002 (halves up). Under heavy concurrent use the balance can briefly dip below $0.
