## 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 optix402-alternatives-intelligence-api-ae4a55e2
```

## When to prefer this

Use this endpoint when you need to discover substitute or competing API services for a specific domain within the x402 pay-per-call ecosystem, particularly when evaluating vendor lock-in risk or exploring marketplace options. Prefer this over general web search when you need structured, x402-native competitive data.

## Known failure modes

- Domain not found in x402 ecosystem — returns empty alternatives array
- Malformed domain parameter — may return 400 or empty result
- Domain has no tracked competitors — alternatives array is empty
- Network timeout from Vercel serverless cold start
- Rate limiting or payment failure at $0.05 USDC per call
