## 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 arkham-token-price-history-411062af -d '<json body>'
```

Example prompt: Pull the Arkham price history for USDC over the last 24 hours — I need the USD price, market cap, and 24h volume at each data point.

## When to prefer this

Choose this endpoint when you need structured historical time-series market data (price, market cap, volume) for a specific crypto token, particularly when Arkham's wallet intelligence data provenance or on-chain tracking is important. Prefer this over generic market data APIs (CoinGecko, CoinMarketCap) when you need Arkham's specific dataset or when integrating with other Arkham wallet/entity intelligence endpoints for a unified data pipeline.

## Known failure modes

- Invalid or unrecognized token symbol/address returns an error or empty array
- Time range too broad may result in truncated or paginated results
- Insufficient USDC balance for x402 payment causes payment failure and request rejection
- Malformed POST body (missing required token or time range fields) returns a 400-level error
- Token with no trading history in the requested range returns an empty array

## How this service works

Get Arkham token price history by pricing ID or chain/address. $0.20 per call.

## Output

Returns a JSON array of time-series data points, each containing a USD price (float), ISO 8601 timestamp, market cap in USD, and 24-hour trading volume in USD. Data points are spaced at varying intervals depending on query parameters.
