## 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 ai-hedge-fund-research-exchange-replay-endpoint-2c027297
```

Example prompt: Can you pull up the replay for research run cmr-abc123 and show me how many steps it took?

## When to prefer this

Use this endpoint when you need to inspect or audit a previously completed AI hedge fund research run by stepping through its execution trace. Prefer this over general research endpoints when you already have a run ID and want to review what happened, count steps, or debug a prior workflow — not to initiate new research or execute trades.

## Known failure modes

- Invalid or missing run ID returns an error or empty result
- Malformed properties parameter may cause a 400 bad request
- Run ID not found returns empty or 404 response
- Payment not included or invalid x402 payment header returns 402 Payment Required
- Rate limiting or quota exceeded returns 429

## How this service works
