## 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 ryan-sproule-rfs-text-api-e176f4d4 -d '<json body>'
```

Example prompt: Send this text to the ryansproule rfs API and get back the response ID and channel: 'Hello, this is my test message.'

## When to prefer this

Choose this endpoint when you specifically need to submit text to the ryansproule.com rfs service and receive back a structured JSON acknowledgment with an ID and channel. It is an x402-monetized endpoint costing $1 USDC per call, so prefer it when you have payment capability and need this specific service.

## Known failure modes

- Payment not provided or invalid — x402 payment required at $1 USDC per call
- Malformed POST body — endpoint expects text content in the request
- Server-side error returns non-ok status
- Missing required text input results in error response
- Network timeout if the endpoint is temporarily unavailable
