## How to call it through Zero

```sh
zero fetch --capability edge-agents-evidence-quality-score-9bcf86f3
```

Example prompt: Can you run an evidence quality score on the momentum and cross-market signals around US tech equities right now — I need to know if the evidence is strong enough to bring to the board, including any contradictions and where the data comes from?

## When to prefer this

Choose this endpoint when you need a machine-readable, provenance-signed confidence score on the quality of market or macro evidence before committing to a strategic or financial decision. It is particularly valuable when decision accountability is high (board, CFO, autonomous agent pipelines) and you need explicit contradiction flags, source coverage statements, and a signed audit trail rather than a raw data dump. Prefer this over generic search or retrieval endpoints when evidence trustworthiness — not just availability — is the primary concern.

## Known failure modes

- Missing or malformed required query parameters — returns error indicating required fields
- No relevant evidence found for the specified topic — returns empty assets array with limitations noted
- Evidence coverage is insufficient — report still returned but limitations field explicitly states gaps
- Service unavailable or payment not processed — returns HTTP 402 if payment header is missing or 5xx on backend failure
- Stale evidence scenario — generatedAt timestamp and limitations array will flag freshness issues rather than silently returning stale data

## How this service works

Scores live market evidence coverage, source availability, cross-source validation and retained trend-window availability. Purpose: Give downstream agents an inspectable quality gate before they rely on Edge Agents market evidence. 5-minute freshness target; missing evidence is reported explicitly rather than invented.

## Output

A JSON object containing an evidence quality status (e.g. 'strong'), a confidence level (e.g. 'high'), an evidence family classification (e.g. 'cross-market'), intent tags (e.g. ['momentum', 'evidence']), a plain-language analysis summary, a list of referenced asset evidence (if any), data completeness status, provenance details including issuer URL and signing status, generation timestamp, schema version, stated limitations, and a standard disclaimer that the output is general market research rather than investment advice.
