Pricing

Billed per token: input and output are priced separately and settled on the upstream's reported usage.

Rates
Input 1.2132Credits/K·Output 6.066Credits/K
  • Input tokens that hit the prompt cache are billed at 121.32 Credits / 1M — cheaper than full-price input.
  • When a turn's prompt exceeds 272,000 tokens, input, cache-hit and output all switch to the long-context rates (input 2,426.4 Credits / 1M). That is the upstream's whole-turn surcharge for very long requests, passed straight through.
  • Failed requests (upstream 4xx / 5xx) are not billed.
  • All your API keys share one balance; when it runs out the API returns HTTP 402 `quota_exceeded`.
