## 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-altcoin-liquidity-quality-score-193889af
```

Example prompt: Can you pull the current altcoin liquidity quality score from Edge Agents and tell me whether liquidity is strong or weak across major altcoins like ETH, SOL, and XRP, along with the confidence level and any key evidence?

## When to prefer this

Choose this endpoint when you need a confidence-rated, provenance-signed liquidity quality assessment specifically for major altcoins (ETH, XRP, SOL, LINK, DOGE) with traceable evidence and explicit contradiction disclosure — rather than a raw price feed, order book snapshot, or generic market data API. It is best suited for decision-makers, autonomous agents, or risk workflows that require bounded, evidence-backed outputs with sourcing rather than raw numerical liquidity metrics.

## Known failure modes

- Payment not included or insufficient (HTTP 402) — request requires $0.01 USDC via x402 protocol
- Data unavailable for a specific asset — report will note coverage gaps in limitations array
- Stale or incomplete source data — dataStatus field may reflect 'incomplete' and limitations will describe freshness issues
- Malformed request parameters — API may return error if required fields are missing or incorrectly typed

## How this service works

Compares ETH, SOL, XRP, LINK and DOGE trading activity, source coverage and cross-source price agreement without claiming order-book depth. Purpose: Rank the observable quality of major-alt market evidence and trading activity, explicitly distinguishing it from executable liquidity. 5-minute freshness target; missing evidence is reported explicitly rather than invented.

## Output

A JSON object containing: a quality status (e.g. 'strong') and confidence level (e.g. 'high'); an analysis summary covering the altcoin family, intents, and narrative; an evidence block listing covered assets (ETH, XRP, SOL, LINK, DOGE), data policy, and sources; provenance metadata with issuer URL and signed flag; a generatedAt timestamp; schema version; data status; and a disclaimer clarifying the report is general market research, not investment advice.
