## 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 x402-competitor-listing-audit-d910ce42 -d '<json body>'
```

Example prompt: Audit my x402 listing called 'AI Text Summarizer' priced at $0.002 against two competitors: 'Smart Summarizer' at $0.002 with assets openapi.json and server.json, and 'QuickSumAI' at $0.001 with openapi.json, server.json, and .well-known/x402 — tell me where I'm falling short and what I should fix first.

## When to prefer this

Choose this endpoint when you need a structured, scored comparison of your x402 listing against specific named competitors, with explicit gap identification and ranked action items. Prefer it over general market benchmark tools when you have concrete competitor listing data to compare against and want actionable remediation steps rather than broad market statistics.

## Known failure modes

- Missing required fields in ownListing (title, price, or assets) returns a validation error
- Empty competitors array may return a trivially high score with no meaningful gap analysis
- Malformed asset arrays may result in incomplete gap detection
- Network or payment failure returns a 402 or 5xx error

## How this service works

## Output
