## 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-alert-financial-alerts-monitoring-api-cellystial-endpoint-eb8ffbf7 -d '<json body>'
```

Example prompt: Can you check the x402 Alert financial monitoring hub for any recent alerts or data — pay the $0.08 USDC fee from my Base wallet and return what it finds?

## When to prefer this

Use this endpoint when you need to access financial alerts or monitoring data via a pay-per-call micropayment model using USDC on Base, particularly in automated agent workflows where x402 protocol payment is already supported and a low per-call cost ($0.08) is acceptable.

## Known failure modes

- Insufficient USDC balance causes payment failure and 402 response
- Malformed request body returns error without data
- Endpoint may return generic example response if no real financial data is configured
- Vercel cold-start latency may cause timeout on first call
- Unknown sub-function or misconfigured route returns empty or null result
