## 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 mondello-dev-x402-emdash-session-status-a370a061 -d '<json body>'
```

Example prompt: Can you check whether https://example.com is set up with x402 micropayments and what its EmDash session status is right now?

## When to prefer this

Use this endpoint when an AI agent needs to programmatically determine whether a specific website supports x402 micropayment gating or has an active EmDash plugin session, especially before attempting to access payment-gated content or integrate with EmDash-powered agent infrastructure on that site.

## Known failure modes

- Invalid or non-HTTPS URL returns validation error
- Site is unreachable or times out — network error response
- Site has no x402 or EmDash configuration — empty or null status fields
- Malformed siteUrl (relative path, missing protocol) — input schema validation failure
- Payment of $0.05 USDC not fulfilled — 402 Payment Required before response is returned

## How this service works
