## 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 coin-railz-portfolio-optimization-3bf58c6d -d '<json body>'
```

Example prompt: Run a portfolio optimization for my AI agent 'AlphaBot' (agent ID: agent-7x9k2) across Ethereum and Base networks and give me the recommended allocation.

## When to prefer this

Use this endpoint when an AI agent needs automated, on-demand crypto portfolio rebalancing or allocation recommendations across one or more blockchain networks, paid per-call via x402 micropayment protocol. Prefer this over manual rebalancing or off-chain tools when operating within an autonomous agent workflow that already uses x402 for payments.

## Known failure modes

- Missing required agentId returns validation error
- Invalid or unknown network identifiers may cause partial results or errors
- Payment failure (insufficient USDC) returns 402 Payment Required
- Service may return generic success without detailed allocation data if optimization logic is incomplete
- Timeout or server error returns non-200 status with error message
