## 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 code402-clean-markdown-scraper-5d82b740 -d '<json body>'
```

Example prompt: Can you fetch the content of https://example.com/blog/article and give me back a clean markdown version of the page, including all the headings?

## When to prefer this

Choose this endpoint when you need a fast, pay-per-call web-to-markdown conversion without running your own scraping infrastructure. It is particularly suitable for agents that occasionally need to fetch and process web content without committing to a subscription, since the first 3 calls per day are free and subsequent calls are $0.015 USDC each via gasless on-chain micropayment.

## Known failure modes

- URL is unreachable or returns non-200 status — likely returns an error object
- Page has no extractable text content (e.g. fully JavaScript-rendered SPA) — markdown may be empty or minimal
- Malformed or missing URL input — request rejected with validation error
- Payment not attached or insufficient — 402 Payment Required response
- Rate limit exceeded beyond 3 free calls/day without payment

## How this service works

Offline deterministic checks (no ML, no scraping) for business identifiers and rental due-diligence, paid per call via x402 (gasless EIP-3009 USDC on Base). Checksum-verifiable (IBAN, LEI, VAT, ABA, ISBN, SEDOL…) vs format-only (EIN, IFSC, SWIFT/BIC…) — every response returns a scope field. Non-custodial, signed receipts. First 3 calls/day free.

## Output

A JSON object containing the full page content as clean Markdown string, a numeric word count, and an array of headings extracted from the page.
