## 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 x402route-vercel-app-db4e9421 -d '<json body>'
```

Example prompt: I need to fetch real-time crypto price data — find me the best x402 endpoint for that task using balanced mode, so I get a good mix of price and quality.

## When to prefer this

Use this endpoint when an AI agent needs to dynamically discover and select the most appropriate paid x402 crypto data endpoint rather than hardcoding a specific provider. Ideal when cost, uptime, or quality optimization across multiple x402 providers is desired.

## Known failure modes

- No matching x402 endpoints found for the given task — returns empty or null recommendation
- Invalid routing mode specified — returns validation error
- Service unavailable or timeout on Vercel deployment — returns 5xx error
- Task description too vague to route accurately — returns low-confidence or generic result
