## 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 stratalize-fx-rate-benchmark-45d65af2
```

Example prompt: Can you pull the latest FX rate benchmark using USD as the base currency — I need the DXY broad trade-weighted index level, major pairs like EUR, JPY, GBP, CNY, and the weekly percent change, all with the cryptographic signature so I can verify the data?

## When to prefer this

Use this endpoint when you need cryptographically signed, independently verifiable FX rate benchmarks sourced from FRED for treasury, international exposure analysis, or macro pricing — especially when auditability and data provenance are required. Prefer over generic FX APIs when the ML-DSA-65 signature and FRED sourcing are important to downstream compliance or model integrity.

## Known failure modes

- Unsupported base currency (only USD, EUR, GBP accepted) returns validation error
- FRED data feed delay may cause stale rates during off-hours
- Payment failure ($0.02 USDC via x402) blocks data return
- Signature verification failure at trust.stratalize.com/verify if receipt is corrupted
