## 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 eth-btc-rotation-signal-f10a7b81
```

Example prompt: Pull the live ETH/BTC rotation signal from Edge Agents right now — I want to know whether momentum and macro evidence favor rotating into ETH, and how confident the signal is.

## When to prefer this

Choose this endpoint when an AI agent or decision-maker needs a live, evidence-backed ETH/BTC rotation signal with explicit provenance, confidence scoring, and stated limitations rather than a raw price feed or unverified market opinion. It is especially valuable for autonomous agents that must justify allocation decisions with sourced, bounded intelligence rather than heuristics.

## Known failure modes

- Payment not received or USDC balance insufficient — endpoint returns HTTP 402 and no signal data
- Live data unavailable — report may indicate incomplete coverage or stale sources in the limitations field
- API timeout or upstream data provider failure — no JSON returned
- Malformed request — endpoint may return an error if required parameters are missing or malformed

## How this service works

Ethereum relative performance versus Bitcoin across live 24-hour and retained 1-hour/24-hour/7-day windows. Purpose: Detect ETH/BTC leadership changes while preserving insufficient-history states and avoiding trade instructions. 5-minute freshness target; missing evidence is reported explicitly rather than invented.

## Output

A structured JSON report containing: signal quality status and confidence level, an analysis object with the asset family, momentum intents (e.g. 'momentum', 'rotation', 'evidence'), and a live findings summary, evidence metadata listing covered assets and policy, a signed provenance record from edge-agents.ai, a generatedAt timestamp, schema version, coverage limitations, and a disclaimer clarifying this is market research and not investment advice.
