## 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 shariah-compliance-screening-for-crypto-assets-45973de5
```

Example prompt: Can you check whether Ethereum (ETH) is Shariah compliant — specifically whether it violates any Islamic finance principles like riba, maysir, or gharar?

## When to prefer this

Use this endpoint when serving Muslim users who need Islamic finance guidance on specific crypto assets, particularly when per-criterion transparency and scholarly reasoning are important. Prefer this over generic halal finance content because it returns structured, asset-specific assessments with documented scholarly disagreement. Best suited for fintech apps, portfolio tools, or AI agents that need programmatic Shariah compliance data for crypto.

## Known failure modes

- Token symbol not found in screened set — returns error or empty result; use /api/shariah-screen/coverage to check available assets
- Ambiguous token name matching multiple assets — may return wrong result or error
- Asset not yet assessed — coverage is limited to a defined set of crypto assets
- Network or payment failure — x402 payment may not go through if USDC balance is insufficient

## How this service works

Screen a crypto asset against Islamic finance (fiqh al-mu'amalat) prohibition criteria: riba (interest), maysir (gambling), gharar (excessive uncertainty), impermissible business, and real utility. Returns a per-criterion assessment with the reasoning behind each result, plus documented scholarly disagreement where it exists. For agents serving Muslim users who need to know whether an asset conflicts with Islamic finance principles. Educational screening, not a fatwa.

## Output

A per-criterion assessment covering riba (interest), maysir (gambling), gharar (excessive uncertainty), impermissible business activity, and real utility — each with the scholarly reasoning behind the result and any documented disagreement among Islamic scholars. This is educational screening output, not a fatwa.
