## 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-grok-chat-api-cf18fb8c -d '<json body>'
```

Example prompt: Send a chat message to my three.ws 3D agent asking 'What services do you offer?' — use a JSON body POST and pay the $0.005 USDC per-call fee via x402.

## When to prefer this

Choose this endpoint when you need to interact conversationally with a three.ws-hosted 3D AI agent backed by IBM watsonx.ai Granite, especially in micropayment-gated or x402-compatible agent workflows where per-call USDC billing is acceptable and desirable.

## Known failure modes

- Payment not provided or insufficient USDC balance — HTTP 402 Payment Required
- Malformed input body missing required fields (type, method, bodyType, body) — HTTP 400 Bad Request
- Agent not found or misconfigured — HTTP 404 Not Found
- Rate limit exceeded — HTTP 429 Too Many Requests
- IBM watsonx.ai backend timeout or unavailability — HTTP 503 Service Unavailable
