## 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-trading-hub-developer-activity-feed-b777911c -d '<json body>'
```

Example prompt: Pull the latest developer activity from the Trading Hub so I can see what's been happening across the on-chain, forex, and stock market endpoints recently.

## When to prefer this

Use this endpoint when you need a consolidated view of recent developer or API activity across the Trading Hub's suite of 67 paid endpoints, particularly for monitoring usage, auditing calls, or understanding activity patterns across on-chain, forex, and stock market data services. Prefer this over individual trading data endpoints when your goal is observability or activity tracking rather than fetching a specific market price or signal.

- Missing or invalid x402 payment header results in 402 payment required response
- Insufficient USDC balance causes payment failure and no data returned
- Service unavailability on Vercel deployment returns 503
