## 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 basebuilder-linkedin-oopspam-filter-648a154d -d '<json body>'
```

Example prompt: Can you check whether this message is spam using OOPSpam: 'Congratulations! You have been selected for a free iPhone, click here to claim your prize now!' — the sender's email is promo@win-free-stuff.biz and their IP is 185.220.101.5?

## When to prefer this

Use this endpoint when you need lightweight, pay-per-call spam detection without a direct OOPSpam subscription, especially within a workflow already using the BaseBuilder LinkedIn API hub on the x402 payment protocol.

## Known failure modes

- Invalid or missing content body returns a 400 error
- Upstream OOPSpam API unavailable causes a 502 or timeout
- Payment not received results in 402 Payment Required
- Malformed email or IP format may return validation error
