## 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 eth-usd-rsi-14-and-macd-12-26-9-momentum-oracle-635d5eda

Example prompt: What are the current RSI(14) and MACD(12/26/9) momentum readings for ETH/USD based on Kraken daily and weekly closes, with the Ed25519-signed attestation?

## When to prefer this

Choose this endpoint when you need cryptographically attested (Ed25519-signed) ETH/USD RSI and MACD technical indicators computed from real Kraken exchange data with Wilder's smoothing, on both daily and weekly timeframes, and you require both completed-bar and forming-bar values. Prefer over unattested or self-reported indicator feeds when auditability and verifiability of the computation method matter.

## Known failure modes

- Payment not provided or invalid x402 payment header — returns 402 Payment Required
- Kraken data unavailable or delayed — may return stale or error response
- Network timeout — endpoint unreachable
- Malformed response if Kraken closes are insufficient to compute full RSI/MACD windows
