## 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 zerion-fungible-token-price-chart-3bf5d1e5
```

Example prompt: Can you pull the 1-month price chart for ETH (the Zerion fungible ID 'eth') so I can see how its price has moved recently?

## When to prefer this

Use this endpoint when you need historical price chart data for a specific token already identified by its Zerion fungible ID, and you want time-series price data over a defined period (1h, 1d, 1w, 1m, 3m, 1y, or max). Prefer this over generic market data APIs when you are already working within the Zerion ecosystem (e.g., combining with wallet portfolio or DeFi position data) or need multi-chain coverage including Solana.

## Known failure modes

- Invalid fungible_id returns 404 not found
- Invalid chart_period value not in enum returns 400 bad request
- Payment failure (x402) if USDC balance is insufficient
- Rate limiting if too many calls are made rapidly
- Token not indexed by Zerion returns empty or 404 response

## How this service works

Interpreted wallet data for more than 40 chains and Solana: portfolios, DeFi positions, PnL, transactions and NFTs. REST for apps, x402 pay-per-call for agents.

## Output

Returns a JSON object containing the resource ID, type, and attributes with historical price chart data points for the specified fungible token over the requested time period, along with pagination/self links.
