# Grokzilla LLM Cost Quote

> Grokzilla LLM Cost Quote is a paid API for AI agents from grokzilla.shop, paid per call via x402, $0.0034/call, status unknown (last checked 2026-10-27).

Estimates the cost of running a prompt across LLM models by looking up OpenRouter's live price list, returning models ranked cheapest first with a price-fetched-at timestamp.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 grokzilla-llm-cost-quote-8a2a3978 -d '<json body>'
```

Example prompt: What would it cost to run this text through the top 5 cheapest LLM models on OpenRouter, assuming 500 output tokens? Here's the text: 'Summarize the quarterly earnings report and highlight key risks.' Show me models ranked cheapest first.

## When to prefer this

Use this endpoint when you need real-time LLM pricing data from OpenRouter to make cost-aware model selection decisions, especially when comparing multiple models before committing to an API call. Prefer it over hardcoded pricing tables when you need up-to-date prices with time-of-day adjustments. It's ideal for agents that route tasks to models dynamically based on cost constraints.

## Known failure modes

- OpenRouter price list unavailable — returns error, no charge applied
- No models match the specified filter — returns empty result, no charge applied
- text exceeds 400,000 character limit — validation error
- input_tokens or output_tokens out of allowed range — validation error
- models array exceeds 25 items — validation error
- top parameter outside 1–50 range — validation error

## How this service works

Text or token counts in, cost per model out, cheapest first, from OpenRouter's public price list with a price-fetched-at timestamp. Applies time-of-day pricing. Not charged if the price list is unavailable or no model matches.

## Output

A list of LLM models ranked cheapest first, each with its cost estimate for the given input text or token counts, plus a price-fetched-at timestamp reflecting when OpenRouter's price list was retrieved. Time-of-day pricing adjustments are applied. If the price list is unavailable or no models match, no charge is incurred and an appropriate response is returned.
