## 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 johto-data-api-web-page-reader-v1-read-1d74a314
```

Example prompt: Can you fetch the content of https://techcrunch.com/2024/01/15/openai-news/ and give me the full article text as markdown, up to 50000 characters?

## When to prefer this

Choose this endpoint when you need to fetch and read the readable text content of a single web page as Markdown, especially when you want clean, LLM-friendly output with token estimates and a content hash. Preferred over general crawlers when you want pay-per-success pricing (no charge on failure), micropayment via USDC on Base (x402), and don't need multi-page or recursive crawling (use /v1/crawl for that). Ideal for research agents, content pipelines, and monitoring workflows that need ad-hoc page reads.

## Known failure modes

- URL is unreachable or returns a non-200 status — not charged, no content returned
- Invalid or malformed URL — request rejected
- Page requires JavaScript rendering — content may be incomplete or missing
- max_chars out of range (must be 1–100000) — validation error
- Rate limiting or bot detection by the target site — fetch fails, no charge
- Providing multiple URLs or a comma-separated list — only one URL is accepted per call

## How this service works

Valuable data. Quality leads. Paid per call in USDC on Base via x402. Not charged if the fetch fails or nothing matches. Prices per call (USDC): /v1/jp-invoice-check $0.002; /v1/sec-13f $0.003; /v1/sec-8k $0.003; /v1/sanctions-screen $0.0025; /v1/tenders $0.011; /v1/uk-tenders $0.003; /v1/fr-tenders $0.006; /v1/au-contracts $0.0035; /v1/wallet-risk $0.0025; /v1/kyb $0.0029; /v1/read $0.0019; /v1/crawl $0.0045; /v1/jobs $0.01; /v1/domain-profile $0.003.

## Output

Returns a JSON object with: the fetched URL, page title, HTTP status code (e.g. 200), full page content converted to Markdown (up to max_chars), a content hash for deduplication/caching, and estimated token counts (for the returned content and the full original). Row count is 1 on success.
