## 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 quantaflow-x402-api-gateway-cnbc-rapid-feed-2dc66e0c -d '<json body>'
```

Example prompt: Fetch the latest top business and market headlines from the CNBC rapid news feed — just give me the most recent stories.

## When to prefer this

Choose this endpoint when you need to access CNBC financial news or market data and are operating in a web3/crypto-native context where x402 micropayments are the preferred payment mechanism. It is especially useful for AI agents with on-chain USDC wallets that want pay-per-call access to financial news without a traditional API subscription. Prefer alternatives if you need bulk data, have a direct CNBC or RapidAPI subscription, or do not have an x402-compatible payment setup.

## Known failure modes

- Payment failure — insufficient USDC balance or x402 payment not accepted, resulting in 402 Payment Required
- Invalid path — the requested sub-path does not exist on the CNBC upstream, returning a 404
- Upstream unavailability — CNBC rapid service is down or rate-limiting, returning a 502 or 503
- Malformed query — invalid query parameters rejected by the upstream with a 400
- Missing required fields — omitting the path parameter may result in a gateway error
