How this service works
Calculate the API cost of an LLM call: input and output tokens × published per-million prices for 15 current models (OpenAI, Anthropic, Google, DeepSeek, xAI, Meta). Batch multiplier included for monthly estimates. Use this when an agent needs to tokens × current per-model prices = USD.
Output
Returns the calculated USD cost for the specified LLM call, broken down by input token cost, output token cost, and total cost, based on current published per-million-token prices for the selected model. If multiple calls are specified, includes a total estimate.
Example use cases
Budget check before deploying agent
“I'm about to run my AI agent in production using gpt-4o — each call uses roughly 1500 input tokens and 400 output tokens. How much will a single call cost me?”
Monthly bill estimate for batch pipeline
“I'm running a nightly batch job that makes 50000 calls to gemini-2.5-flash each month, with about 800 input tokens and 200 output tokens per call. What's my estimated monthly API cost?”
Model cost comparison for budget planning
“What does one call to grok-3 cost if I use 2000 input tokens and 1000 output tokens? I'm trying to decide between models based on price.”

Endpoint
GEThttps://agentstoolshub.com/api/v1/dev/llm-cost-calculator?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, accurate USD cost estimate for a specific LLM model call using current published pricing. It covers 15 models across all major providers (OpenAI, Anthropic, Google, DeepSeek, xAI, Meta) in a single call, making it ideal for cost-aware agents, budget planning tools, or monthly spend estimators — without having to hardcode or maintain pricing tables yourself.
Side effects
- Missing required inputTokens parameter returns a validation error
- Unsupported or misspelled model name returns an enum validation error
- Negative or non-numeric token counts may cause a 400 bad request
- Network or upstream pricing data unavailability returns a 5xx error
