## How to call it through Zero

```sh
zero fetch --capability eth-etf-flow-pulse-27bfd166
```

Example prompt: Pull the latest ETH ETF Flow Pulse report — I need current Ethereum ETF capital flow data with confidence levels and provenance so I can brief the investment committee on institutional liquidity trends.

## When to prefer this

Choose this endpoint when you need evidence-backed, provenance-signed ETH ETF capital flow analysis with explicit confidence scoring and stated limitations — particularly for use cases requiring auditability (board reporting, compliance, autonomous agent decision trails). Prefer this over generic crypto data APIs when you need bounded decisions with contradictions disclosed and sources attributed, not raw price feeds or unannotated market data.

## Known failure modes

- Payment not provided or invalid — endpoint requires $0.01 USDC via x402 protocol
- Data unavailable for the requested period — dataStatus field may reflect incomplete coverage
- Source freshness issues — report will explicitly state coverage gaps rather than infer
- Network timeout — retry with exponential backoff
- Invalid request format — malformed query parameters

## How this service works

Evidence-gated spot-Ethereum ETF share creation/redemption pulse from configured SEC public-record observations; missing filings remain unavailable. Purpose: Measure recognised spot-Ethereum ETF share-count creation/redemption without presenting it as dollar flow, AUM change or secondary-market turnover. 5-minute freshness target; missing evidence is reported explicitly rather than invented.

## Output

Returns a structured JSON report including: analysis summary with ETH ETF family and identified intents (e.g. liquidity, etf, evidence), quality status and confidence rating (e.g. strong/high), evidence assets and policy, provenance with issuer URL and signed flag, generatedAt timestamp, schema version, data status, known limitations, and a disclaimer clarifying the report is market research and not investment advice.
