## 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 x402-price-api-multi-endpoint-quote-788f0c0c
```

Example prompt: Before I run my multi-endpoint workflow on the x402 API, can you get me a quote for the total cost so I know how much USDC I'll need?

## When to prefer this

Use this endpoint when you need to preview or budget the total USDC cost of a multi-endpoint x402 API workflow before committing to payment. Prefer this over directly calling paid endpoints when cost confirmation is required, or when orchestrating agent workflows that need to verify spend limits.

## Known failure modes

- Missing required 'input' parameter returns a validation error
- Invalid HTTP method (non-GET) returns a 400 or schema validation error
- Endpoint unavailable returns 502 or timeout
- No endpoints specified in query results in a zero or error response
- Unexpected workflow configuration may return an unparseable result
