## How to call it through Zero

```sh
zero fetch --capability mycealiasignal-eth-funding-rate-history-aaad760c
```

Example prompt: Pull up the ETH/USD perpetual funding rate history for the last 18 days — I want to see per-exchange rates and get the signed attestation I can verify.

## When to prefer this

Use this endpoint when you need cryptographically attested ETH perpetual funding rate history over the past 18 days, especially when downstream consumers need to verify data provenance via Ed25519 signature. Prefer over generic market data APIs when attestation/auditability is required, or when comparing ETH funding rates across multiple named exchanges in a single call.

## Known failure modes

- Invalid exchange filter value returns error or empty dataset
- Payment failure (x402) if USDC not provided or insufficient
- Network timeout if exchange data sources are unavailable
- Signature verification failure if attestation key is rotated
- Empty result if no funding rate events in the window
