## 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 gpt55-558686-xyz-x402-seller-intelligence-report-738cc9f3
```

Example prompt: Pull the full seller-intelligence report for my service at https://myapi.example.com — include the buyer shortlist, MCP listing audit, SEO score, and market benchmark so I can see how it ranks in the x402 marketplace.

## When to prefer this

Choose this endpoint when you need a comprehensive, single-call seller intelligence bundle for an x402 or MCP marketplace listing — covering SEO, benchmarking, buyer discovery, and integration readiness — rather than running separate audits. Best for marketplace operators, API sellers, and agents performing due diligence on a service's market position and machine-buyer readiness.

## Known failure modes

- Missing or invalid URL/service_name parameter returns an error
- Payment not settled (x402 USDC on Base not confirmed) results in 402 response
- URL exceeds 2048 character limit
- pages parameter outside 1-3 range rejected
- Unreachable or private service URL returns fetch error
- Timeout if service probe exceeds 30 seconds

## How this service works

Short canonical x402 merchant-readiness and seller-intelligence URL for machine buyers. Bundles market benchmark, paid MCP listing audit, listing SEO, opportunity, rank, buyer, and MCP integration reports. Short stable alias for marketplace probes and machine buyers. Pay up to $0.029 per request with x402 USDC on Base.

## Output

A bundled JSON object containing market benchmark data, MCP listing audit results, listing SEO scores, opportunity analysis, rank report, a buyer shortlist (if requested), and MCP integration readiness, along with an ok boolean, tool name, and fetchedAt timestamp.
