## 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 base-defi-yield-opportunity-risk-card-81e03612
```

Example prompt: Pull the full risk card for Base DeFi opportunity e0672197-9f3e-4414-bca5-e6b4c90aa469 — I want the risk score, main risks with evidence, yield sources, and expected return on $25,000 over 180 days.

## When to prefer this

Use this endpoint when you need a comprehensive, scored risk assessment for a single known Base DeFi yield opportunity before depositing, recommending, or comparing it. It is the richest single-call source of risk intelligence for a Base yield — covering risk score, yield breakdown, liquidity, dependencies, and recent incidents in one response. Prefer it over the sibling scoring-breakdown endpoint when you want a summarized card rather than a full factor-by-factor breakdown, and over the history endpoint when you need current state rather than time-series trends.

## Known failure modes

- 404 if the opportunity id is not found in the tracked set — caller should first fetch valid ids from /api/v1/opportunities
- 400 if path or query parameters are invalid (e.g. id format mismatch, capital out of range, duration out of range) — returned before any charge
- 503 if the underlying data pipeline is refreshing — transient, retry after a short delay
- Payment/402 failure if the x402 payment of $0.01 USDC is not completed — endpoint charges only on a 200 response

## How this service works

Full risk card for one Base yield opportunity: 0-100 risk score with the main risks and their evidence, yield sources, sustainable APY, expected return, liquidity, dependencies and recent risk events. Useful before depositing into, recommending or comparing a Base yield. The id comes from the free /api/v1/opportunities. Unknown ids answer 404 and invalid arguments 400 before any payment; 503 while data refreshes; charged only for a 200.

## Output

A JSON object containing: the opportunity id, timestamp of data, model version, risk score (0-100), opportunity score, confidence level, quoted APY, sustainable APY, yield sources broken down by APY share, major risk dimensions with supporting evidence, liquidity rating, protocol/asset/oracle dependencies, recent risk events (exploits, depegs, TVL drops), expected return figures based on supplied capital and duration, and a data freshness indicator.
