How to read Gemini API pricing

Gemini API cost is not only the listed token price for a model. Input-output token split, context size, caching behavior, tool calls, retries, and error rate shape the real cost.

API key security

A Gemini API key, or any LLM API key, should not be written into frontend code, mobile apps, or public repositories. Read it server-side and pair it with budget and rate limits.

  • Store API keys in environment variables or a secret manager.
  • Track per-user spending limits and rate limits separately.
  • Do not log Authorization headers or raw keys.
  • Prepare fast revoke and rotation if a key leaks.

A practical cost formula

Total cost is not only the token price of successful answers. System prompts, user input, retrieval context, model output, tool results, retries, and failed attempts should be counted together.

Separate LLMTR credit margin from model price

In LLMTR, model prices remain catalog values. The platform margin is not added to token prices; it is applied as 8% on credit top-ups.

Calculate Gemini API cost

Estimate Gemini API usage by separating model price, token usage, retries, and platform credit handling.

  1. Choose model and task. Select the Gemini model and task type; separate chat, agent, and multimodal workloads.
  2. Collect token sources. List system prompt, user input, retrieval context, tool output, and model answer separately.
  3. Add retry rate. Include requests retried due to timeouts, provider errors, or quality failures.
  4. Show credit margin separately. Keep model price unchanged and show LLMTR's 8% platform margin as a credit top-up payment item.

Frequently asked questions

Is a Gemini API key free?

Free-tier or trial terms can change. Check official pricing and quota documentation before production planning, and handle key security separately.

Does LLMTR add margin to Gemini model prices?

No. Model usage prices remain catalog values; the 8% platform margin applies to credit top-ups.
