## 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 three-ws-wallet-connect-health-check-8f710ffe -d '<json body>'
```

Example prompt: Run a health check on the three.ws wallet-connect endpoint to see if it's up, whether sessions are being created successfully, and what the current latency looks like.

## When to prefer this

Use this endpoint when you need to verify that the three.ws x402 wallet-connect infrastructure is operational before initiating agent chat sessions with micropayments, or when diagnosing payment or session-creation failures on embedded 3D agents.

## Known failure modes

- Non-health mode values in 'mode' enum may be rejected
- Service unavailability may return non-200 status or timeout
- nonce_valid: false indicates authentication/nonce infrastructure issues
- session_created: false signals session layer failures
- slow: true indicates degraded performance without full outage
- x402 payment of $0.001 USDC required; insufficient funds will block the call

## How this service works

Make a 3D AI agent from a selfie in 60 seconds. Drop one HTML tag to embed it on any website. Agents think on IBM watsonx.ai (Granite); optionally charge per chat with built-in micropayments.

## Output

Returns a JSON object with mode ('health'), a boolean 'slow' flag, the domain ('three.ws'), a nullable 'reason' field, a 'checked_at' ISO timestamp, latency in milliseconds, a 'nonce_valid' boolean, and a 'session_created' boolean indicating full infrastructure readiness.
