Every model at its list price.

The usage allowance is a monthly limit on requests routed to the nrouter/auto model for existing subscribers. It is not a credit balance and has no cash value. Unused allowance does not roll over and expires when the window resets. On Pay as you go, nrouter/auto is paid directly from credits at the served model's list price.

nrouter/auto is automatic routing: send it as the model and nRouter chooses an eligible model from the published chat models your organization allows, without you needing to specify a provider. Best for the task (the default) uses smart model selection when it is available; Lowest cost orders the models fit for the task by their list rate. The response names the model that answered in x-nr-model. It is available to Pay as you go customers and paid from credits at the served model's list price.

Yes. nRouter manages provider keys for you on credits, or you can bring your own OpenAI and Anthropic keys on the Bring your own keys plan ($20/mo, 50M tokens/mo included for text chat). Other models keep running on credits. Developers change nothing: use the same sk-nrouter key, endpoint, and SDK. Each response says who paid in the x-nr-funding-source header (byok or credits).

Pay as you go rate limits are 200 RPM, 200k TPM, and 5 concurrent requests. If you exhaust your credit balance, requests pause until you purchase more credits (credits never go negative). Existing subscribers with a usage allowance who reach an 8-hour window limit must wait for the window to reset or fund extra usage from credits.

Capacity is shared across all customers in your tier. During peak times, a request can wait or be asked to retry. Enterprise plans include dedicated capacity and custom SLAs.

Request logs are retained for up to 30 days, depending on your plan; prompt and response text are never stored. Platform audit logs are kept for 18 months, auth events for 12 months, and financial records for 7 years.

Credits are non-refundable once consumed by API usage. Unused credit balances may be refunded upon account closure, subject to our refund policy. Every refund request is reviewed by a person before it is issued.

Pay as you go carries a 0% platform fee: $100 of credits costs $100.00, and the $5 minimum purchase costs $5.00. You receive 100% of the credits you buy, and usage settles at the served model's list price.

We do. nRouter covers the card processing fee, so the $5 purchase charges your card $5.00 and adds $5.00 of credits. Payments are processed by Stripe: your card details go straight to Stripe and never reach nRouter's servers.

nRouter charges 0% token markup — you pay exact upstream model rates — plus a flat 0% platform fee on Pay as you go credits. OpenRouter publicly lists a 5.5% fee on credit purchases (as of October 2026). Both gateways pass through underlying model costs; the difference is the platform fee on top.
