## 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 eni-standard-feed-8748e8d7
```

Example prompt: Fetch me the ENI standard data feed — just a single request, paying the 1-cent USDC fee.

## When to prefer this

Choose this endpoint when you need a single, low-cost data fetch from the ENI feed at the standard tier and are comfortable with x402 USDC micropayment flow. Use over premium/pro/enterprise tiers when cost minimization matters and standard data quality suffices. Prefer over basic/micro tiers when you need at least standard-grade data output.

## Known failure modes

- Payment not completed — 402 response returned if x402 USDC payment is not included or fails
- Invalid or expired payment — request rejected with payment error
- Rate limiting or quota exceeded — server may reject repeated rapid calls
- Endpoint unavailable — worker may be offline or misconfigured

## How this service works
