## 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 edge-agents-market-data-freshness-check-e918f3c2
```

Example prompt: Can you run a market data freshness check on Edge Agents and tell me if the cross-market evidence we're using is current, high-confidence, and properly sourced before I take this into the board meeting?

## When to prefer this

Choose this endpoint when you need to verify the freshness and quality of cross-market data before relying on it for strategic decisions, board presentations, or autonomous agent workflows. It is particularly suited for decision intelligence pipelines where provenance, confidence scoring, and explicit limitations matter — not just raw data retrieval. Prefer this over generic market data APIs when you need signed provenance, bounded confidence assessments, and contradiction flagging rather than raw price feeds.

## Known failure modes

- Missing or malformed required parameters returns an error with no report
- Payment failure (non-payment of $0.01 USDC) results in HTTP 402 and no data returned
- Data unavailability for requested assets results in empty assets array with limitations noted in report
- Stale or uncrawlable sources may result in lower confidence scores rather than a hard error
- Response may include limitations array if coverage is incomplete for the requested scope

## How this service works

Machine-readable status and age checks for every live market, sentiment and validation source used by the Edge Agents market layer. Purpose: Let machine buyers verify whether current market evidence is fresh enough for downstream use. 5-minute freshness target; missing evidence is reported explicitly rather than invented.

## Output

A JSON report containing: overall data freshness status (e.g. 'strong'), confidence level (e.g. 'high'), data family classification (e.g. 'cross-market'), identified market intents (e.g. 'evidence', 'sentiment'), a human-readable findings summary, a list of asset evidence, the data policy (e.g. 'live'), source provenance with issuer URL and signed flag, generation timestamp, schema version, limitations disclosure, and a standard non-investment-advice disclaimer.
