## 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 vape-token-chart-daily-price-series-logo-d76d0014
```

Example prompt: Can you pull up the last 30-day daily price chart for the token at contract address 0x4200000000000000000000000000000000000006 on Base, including its logo, so I can see how volatile it's been?

## When to prefer this

Use this endpoint when you need historical daily price data for a specific token contract to render sparklines, compute volatility metrics, or display a price chart with the token's logo. Prefer this over token_intel when the primary need is historical price series rather than a current snapshot or full token dossier.

## Known failure modes

- Invalid or unrecognized token contract address returns an error or empty data
- Unsupported chain slug returns an error
- Span value out of supported range may return partial or empty series
- Payment not completed (x402) results in 402 response blocking data
- Network or upstream data provider unavailability causes 5xx error

## How this service works

VAPE token_chart — Daily price series for a token (default 30d), plus the token's real logo — feeds sparklines and a rule-based volatility read.

## Output

Returns a daily price time series covering the requested span (default 30 days), the token's real logo image reference, and a rule-based volatility read derived from the price data — suitable for rendering sparklines or computing price volatility summaries.
