Recharge credits for an OpenAI-compatible relay

NexRelay uses prepaid credits with separate input, output, and cached read token meters. This is an independent third-party gateway, not an official OpenAI service.

Starter

For prototypes, small tools, and light API usage.

Token meters

MeterUnit priceBilling note
Input tokens$1.00 / 1M creditsBilled from reported request usage.
Output tokens$1.00 / 1M creditsBilled from reported request usage.
Cached read tokens$0.10 / 1M creditsCache hits are billed at a lower weighted rate.

Deduction example

A request with 100,000 input tokens, 20,000 output tokens, and 50,000 cached read tokens deducts 125,000 credits, equal to $0.1250.

Formula: input credits + output credits + cached read credits x 0.1.

Billing rules

  • Each API request has one request id and can be billed at most once.
  • Balance is checked before the upstream request. Insufficient balance returns 402 and no upstream request is sent.
  • Successful requests are billed from actual input, output, and cached read token usage when upstream usage is available.
  • Upstream failures before a usable response are not billed. Partial successful streamed responses can be billed by reported usage.
  • Retries and abnormal traffic are logged; repeated failures or high retry rates may be rate-limited or reviewed.
