## 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 btc-realised-volatility-term-structure-a67b4885
```

Example prompt: Can you pull the current Bitcoin realised volatility term structure from Edge Agents — I need the confidence level and source provenance so I can include it in today's risk briefing?

## When to prefer this

Choose this endpoint when you need signed, provenance-tracked Bitcoin realised volatility term structure data with explicit confidence scoring and contradiction flagging — especially for institutional, audit-trail, or autonomous-agent workflows where data lineage matters. Prefer it over generic crypto data feeds when you need bounded, evidence-cited analysis rather than raw price or implied volatility figures.

## Known failure modes

- Payment not completed — 402 response if USDC payment via x402 protocol is missing or invalid
- Data unavailable — report may flag incomplete coverage if source data is stale or missing for certain tenors
- Low confidence result — quality.confidence may return 'low' if contradicting evidence is found
- Schema mismatch — clients expecting schema v1 responses may fail on v2 structure
- Rate or network errors — transient failures may return 5xx responses requiring retry

## How this service works

Annualised realised-volatility estimates over retained 1-hour, 24-hour and 7-day Bitcoin observation windows with minimum-history and coverage gates. Purpose: Compare short and longer Bitcoin realised-volatility horizons using retained point-in-time observations without substituting options implied volatility. 5-minute freshness target; missing evidence is reported explicitly rather than invented.

## Output

Returns a JSON object containing: quality status and confidence rating, a family/asset label (Bitcoin/BTC), an intent and summary analysis, evidence details including assets covered and sourcing policy, a generated timestamp, signed provenance from edge-agents.ai, schema version, and stated limitations about coverage and source freshness. The report is point-in-time and includes a disclaimer that it is general market research, not investment advice.
