## 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`):

Example prompt: What are the current input and output token prices for claude-sonnet-5 on modelprices.xyz — I need the per-million-token rates to estimate my API costs.

## When to prefer this

Use this endpoint when you need precise, normalized per-token pricing for a single known LLM model ID and want a lightweight single-model lookup rather than a full pricing table. Prefer this over scraping provider websites or using the comparison table endpoint when you already know the model ID and just need its current rates programmatically.

## Known failure modes

- Unknown or misspelled model ID returns no match or 404
- Model exists but pricing data not yet available for new releases
- Stale data if called within same hour as a provider repricing event
- Ambiguous model IDs (e.g. 'claude-3' without version) may not resolve correctly
- Network timeout or payment failure (x402 $0.002 USDC) blocks the response

## How this service works

Per-token prices, capability limits, and a price-change feed for 2,000+ LLMs across 70+ providers, normalized into single JSON tables and refreshed hourly.

## Output

A JSON object containing the model's canonical ID, provider name, input price per million tokens, output price per million tokens, cache read price per million tokens, and a timestamp indicating when the data was last refreshed (hourly cadence).
