## 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 corpusai-llm-token-price-history-16bb7937
```

Example prompt: Pull the historical daily token prices for the CX.TOK.FRONTIER.BLEND ticker from January 1, 2024 to today so I can see how frontier LLM costs have trended.

## When to prefer this

Use this endpoint when you need programmatic access to historical LLM token pricing data for a specific model or blended index ticker, particularly for trend analysis, cost forecasting, or audit purposes. It is the right choice over manual research or static datasets when you need daily granularity with hi/lo ranges going back to 2023 or earlier.

## Known failure modes

- Missing or invalid ticker returns an error — ticker is required
- Invalid date format (non-YYYY-MM-DD) will cause a validation error
- Date range with no available data returns an empty series
- Payment failure via x402 (insufficient USDC balance) blocks the request
- Unknown ticker symbol returns not-found or empty response
