## 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 optix402-buyer-activity-analytics-5930a6df
```

Example prompt: Pull the latest buyer activity from the Optix402 x402 marketplace intelligence feed so I can see who's been purchasing API calls and how active buyers are right now.

## When to prefer this

Choose this endpoint when you need real-time visibility into who is buying within the x402 micropayment ecosystem specifically — not general e-commerce or web2 payment analytics. Best suited for x402 network participants, API marketplace operators, or agents monitoring x402 ecosystem health and buyer-side demand signals.

## Known failure modes

- Empty activity array returned when no recent buyer activity exists
- 402 Payment Required if USDC micropayment is not properly attached
- Network timeout if the Vercel deployment is cold-starting
- Invalid or malformed response if upstream x402 data pipeline is unavailable
- Rate limiting or authentication errors if payment header is missing or incorrect
