## 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 deltasignal-alpha-opportunities-audit-27836523
```

Example prompt: Pull me the DeltaSignal alpha opportunities audit for source date 2026-05-13, filtered to operating companies only, and include the row-level details — I want to see the rank delta summary and issuer type breakdown.

## When to prefer this

Use this endpoint when you need a high-level audit of alpha opportunity rankings across issuer types — particularly when you want to identify which issuers experienced the largest rank shifts or demotions on a given date. Prefer this over individual issuer signal endpoints when you need a population-level summary rather than a single-issuer deep dive.

## Known failure modes

- Invalid issuer_type enum value returns a validation error
- source_date in wrong format or future date may return empty or error response
- limit parameter set too high may return truncated results
- Missing required input object causes schema validation failure
- Service unavailable due to upstream data pipeline delays

## How this service works

Explain alpha board issuer-type, identity, quality, and board-rank gates.

## Output

Returns a JSON object containing the source_date, default_filter applied, a rank_delta_summary with max_rank_delta and rows_with_demotion counts, and an issuer_type_summary breaking down counts by operating_company, etf_trust, fund_vehicle, and foreign_issuer.
