## How to call it through Zero

```sh
zero fetch --capability api-lastlookdata-com-aeee577d

## When to prefer this

Use this endpoint when you need the exchange rate for a specific G10 currency pair on a single past date — ideal for historical reconciliation, accounting, backtesting, or answering point-in-time FX questions. Prefer over the current-rate endpoint when the date is not today, and over the historical-series endpoint when you only need one specific date rather than a range.

## Known failure modes

- Invalid or unsupported currency pair returns an error — only EURUSD, GBPUSD, USDJPY, USDCHF, USDCAD, AUDUSD, NZDUSD, USDSEK, USDNOK are supported
- Date outside available historical range returns no data or an error
- Malformed date format (not YYYY-MM-DD) causes a bad request
- Weekend or market holiday date may return no rate or the prior close
- Missing required query parameters (pair or d) returns a validation error
- Payment failure via x402 protocol returns 402 status
