## 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-portfolio-time-series-by-address-11186725 -d '<json body>'
```

Example prompt: Pull the time-series portfolio history for Ethereum wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 from Arkham — I want to see how its holdings across Ethereum mainnet and Arbitrum changed over November 2024.

## When to prefer this

Use this endpoint when you need time-series historical portfolio data for a specific blockchain wallet address, including per-token balances and USD valuations across multiple chains. Prefer this over simple balance lookups when trend analysis, historical snapshots, or time-windowed portfolio performance is needed. Arkham is especially valuable when the wallet belongs to a known entity or institution indexed in Arkham's intelligence graph.

## Known failure modes

- Invalid or unrecognized wallet address returns empty or error response
- Insufficient USDC balance for x402 payment results in payment failure and no data returned
- Address with no on-chain history returns empty time-series object
- Unsupported network or chain parameter returns partial or null data
- Rate limiting or API key issues result in 401/429 errors

## How this service works

Get Arkham daily portfolio time series for an address token. $0.40 per call.

## Output

A JSON object keyed by ISO 8601 timestamps, each containing a breakdown by blockchain network and token: includes asset ID, token name, symbol, current price in USD, token balance, and total USD value. Covers multiple chains (e.g. Ethereum mainnet, Arbitrum One) in a single response.
