## 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-x402-seller-intelligence-bundle-a08ba08c
```

Example prompt: Can you run the full seller intelligence bundle for my service called 'Morning Bloom AI Assistant' — I want the market benchmark, listing SEO score, buyer shortlist, and MCP integration report, and include the buyer shortlist results?

## When to prefer this

Choose this endpoint when you need a comprehensive, all-in-one seller intelligence snapshot for a marketplace or MCP-listed service — especially when you want to avoid making multiple separate calls for benchmarking, SEO, rank, buyers, and MCP audit. Ideal for AI agents operating in the x402 micropayment ecosystem on Base that need machine-readable marketplace intelligence in a single paid request.

## Known failure modes

- Payment not settled — missing or malformed X-PAYMENT header returns 402 with payment instructions
- service_name or url parameter missing — returns 400 validation error
- Timeout exceeded (timeout_ms > 30000) — returns timeout error
- Downstream marketplace probe unavailable — returns partial report or 503
- Invalid USDC payment amount — payment rejected before report is generated

## How this service works
