## 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-silverbackdefi-app-2570c20e -d '<json body>'
```

Example prompt: What DeFi capabilities does SilverbackDeFi expose for AI agents — can you discover and list all the available endpoints including things like whale monitoring, swap routing, and technical analysis?

## When to prefer this

Use this endpoint when an AI agent needs to dynamically discover what SilverbackDeFi capabilities are available before calling specific endpoints, or when building an orchestration layer that needs to enumerate available DeFi tools at runtime.

## Known failure modes

- Payment not included or invalid — 402 response requiring USDC payment
- Malformed POST body — 400 bad request
- Service temporarily unavailable — 503 error
- Rate limiting if called excessively in short window

## Output
