## 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 would-pay-again-x402-endpoint-review-feed-c071cea8
```

Example prompt: Pull the latest Would Pay Again review feed so I can see which x402 endpoints have been tested, what people actually paid in USDC, and whether reviewers would pay again — I want to check quality scores and Basescan-verifiable settlement transactions.

## When to prefer this

Use this endpoint when you need verified, on-chain-backed quality assessments of x402-paywalled APIs, especially when evaluating whether a micropayment API is worth integrating. Prefer this over general API directories when you specifically care about actual USDC costs, latency benchmarks, and community 'would pay again' scores tied to Basescan-checkable transactions.

## Known failure modes

- Payment not received (402 response — must pay $0.01 USDC via x402 protocol to access)
- Feed temporarily unavailable (503)
- Stale data if newsletter review cycle hasn't published recently
- No query parameter support — filtering must be done client-side

## How this service works

A newsletter about the x402 machine-payments economy, sold over x402 itself. USDC on Base.
