# LLM Cost & Capacity Calc – Batch Discount Savings

> LLM Cost & Capacity Calc – Batch Discount Savings is a paid API for AI agents from llm-cost-calc.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-29).

Compares realtime vs. batch API cost for an LLM workload given token counts, prices, and a discount fraction, and returns how much money is saved by using batch mode.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability llm-cost-capacity-calc-batch-discount-savings-0daf5a01
```

Example prompt: How much would I save using batch mode instead of realtime for a job of 50,000 requests, each with 800 input tokens and 200 output tokens, at $5 per million input tokens and $15 per million output tokens, with a 50% batch discount?

## When to prefer this

Use this endpoint when you need a quick, structured comparison of batch vs. realtime LLM API costs for a defined workload — especially when you have your own per-million-token prices and want to quantify savings from a specific discount fraction. Prefer it over manual spreadsheet math or generic cost calculators when building automated pipelines that need to decide whether to queue work for batch or process immediately.

## Known failure modes

- Missing required query parameters (inputTokens, outputTokens, requests, inputPricePerMTok, outputPricePerMTok) returns an error
- Non-numeric or out-of-range values (e.g. requests > 1e9 or batchDiscount > 1) may return validation errors
- Service degradation indicated by degraded=true flag in response with partial results
- Payment failure via x402 protocol blocks access if USDC balance is insufficient

## How this service works

Compare realtime and batch API cost for a workload with your discount fraction, and the money saved by waiting.

## Output

Returns realtime total cost, batch total cost, savings amount, discount percent applied, cost per request for both modes, a verdict on whether batch is worth it, a human-readable summary, and optional reasons or disclaimers. May also include degraded/source/asOf metadata fields.
