## How to call it through Zero

```sh
zero fetch --capability xynaptic-company-compare-64e906ef
```

Example prompt: Can you compare these two French companies side by side — SIREN 552 032 534 (Carrefour) and SIREN 542 107 651 (Auchan) — I want to see how they differ in size, financials, activity, geography, and any risk signals?

## When to prefer this

Use this endpoint when you need a direct, structured comparison of exactly two French companies for due diligence, procurement evaluation, competitive analysis, or investment screening. Prefer this over single-company lookup endpoints (like Xynaptic Company Financial) when the goal is to contrast two entities rather than deep-dive into one. Ideal for workflows that require an A/B decision between two French business entities identified by SIREN numbers.

## Known failure modes

- Invalid or non-existent SIREN number returns an error or empty result
- Missing one or both SIREN parameters causes a validation error
- Companies with no filed financial data may return incomplete financial comparison
- Very recently registered companies may have limited registry data
- Rate limiting or payment failure if USDC payment is not processed correctly
