Simple per-token pricing.

Prepaid credits · billed in USD · pay by card

You buy credits up front, allocate them to API keys, and every request draws down the key by its exact token count, plus any tool calls it made, billed to $0.000001. One key works with every model we serve. No subscriptions, no minimum commitment beyond the first top-up.

glm-5.3 is billed at 45% of Z.ai’s official GLM-5.3 price (struck through above) — 55% off. glm-5.3-fast is the same GLM-5.3 on a faster lane with priority scheduling. glm-5.2 is billed at Z.ai’s official rate. Pick the model per request with the model field ("model": "glm-5.3"), or ANTHROPIC_MODEL=glm-5.3 for Claude Code — details in the docs. Prices are USD per million tokens. A cache hit is an input token whose prefix was already processed in a recent request; it is billed at a fraction of a miss, so multi-turn conversations stay cheap. Reasoning tokens are billed as output.

Tool calls

Charged per completed search, at list price, on top of the request’s tokens; the results the model reads are billed as input tokens. Failed searches are free. The count is in usage.server_tool_use and in the console.

How credits work

• Top up your wallet by card: whole US dollars, from $5 to $1,000 per transaction. You are charged exactly the amount you enter.
• Create a key and choose how much credit to put on it. The key can spend up to that amount across any model.
• Adjust any time. Add credit to a key, reclaim what it hasn't used, or delete it — unused credit returns to your wallet. A key can spend slightly past its credit when requests run in parallel; that difference is charged to your wallet when the key is deleted.
• Track spend live in the console: per-key usage updates every 30 seconds, with a daily breakdown by tokens and cost.

Credits are prepaid and non-refundable except as set out in our Refund Policy. Need higher limits, invoicing, or a private deployment? Email contact@supernova-labs.ai.
