## 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 swaphunt-macro-event-history-bb4e3ce0
```

Example prompt: Pull the historical macro events for the US over the last 90 days — I want to see which ones came in above or below forecast so I can study how markets reacted to surprises like CPI and NFP.

## When to prefer this

Use this endpoint when you need historical macroeconomic event data with actual vs. estimate comparisons for backtesting event-driven trading strategies or studying market reactions to economic surprises. Prefer this over forward-looking endpoints when you need past release data with surprise values rather than upcoming scheduled events.

## Known failure modes

- Invalid date format returns 400 — must use ISO YYYY-MM-DD
- Unknown country code returns empty results or 400
- days parameter out of supported range may return partial data or error
- Payment not processed (x402 flow failure) returns 402
- No events in specified range returns empty array

## How this service works

Historical macro events with actual vs estimate values (e.g. CPI came in above/below forecast). Use to study how markets reacted to surprises and to backtest event-driven strategies.

## Output

A list of historical macroeconomic events with their scheduled dates, country, event name (e.g. CPI, NFP, FOMC), the consensus estimate, the actual reported value, and the surprise direction/magnitude. Useful for identifying market-moving surprises and building backtests.
