## 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 apex-x402-bazaar-rank-check-ae2b9f17
```

Example prompt: Check where my x402 endpoint at https://myapi.example.com/api/data ranks in Coinbase Bazaar when agents search for 'weather data, realtime api, forecast' — and tell me what I need to fix to rank higher.

## When to prefer this

Use this endpoint when you are an x402 API seller wanting to understand your discoverability in Coinbase Bazaar search, benchmark against competitors, and get specific fixes for your listing. Prefer this over generic SEO tools because it is purpose-built for the x402/Bazaar ecosystem and returns Bazaar-specific signals like 30-day payer counts and x402-relevant tag recommendations.

## Known failure modes

- URL not publicly reachable or not a valid x402 endpoint — returns error or no rank data
- Endpoint not listed in Bazaar at all — returns unranked with no position data
- Query string contains more than 3 comma-separated terms — may return error or only process first 3
- Bazaar search index temporarily unavailable — may return empty or stale results
- Invalid URL format (not starting with http/https) — rejected by schema validation

## How this service works

Bazaar SEO for x402 sellers: where your endpoint ranks in Coinbase Bazaar search and what to fix. Where does your x402 endpoint come up when an agent searches Coinbase's Bazaar? Pass ?url= and optionally &query= (up to 3; left out, your own tags are searched). For each search: your rank in the top 20, the sellers above you with their price, tags and 30-day payers, the median price, and the concrete fixes (serviceName, tags, the words your description opens with).

## Output

For each queried search term: your endpoint's rank in the top 20 results (or not found), a list of sellers ranked above you with their name, price, tags, and 30-day payer count, the median price across results, and concrete actionable fixes covering service name, tags, and description opening words.
