## 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 inferrail-web-read-3a9952a1
```

Example prompt: Can you read the page at https://example.com/article and give me the full content as clean text? I only want to pay if it actually loads.

## When to prefer this

Choose this endpoint when an agent needs to read the human-readable text of a single public web page and convert it to clean markdown, especially in cost-sensitive agentic workflows where you only want to pay for successfully delivered pages. The idempotent retry mechanism (same url + request_id = no double charge) makes it safe for unreliable networks. Prefer this over general-purpose scraping services when operating on the x402/Base payment rail or when per-page micropayment billing is preferred over subscription scraping APIs.

## Known failure modes

- Target site returns a 4xx or 5xx error — not charged, error status returned
- Target site blocks automated access or returns a CAPTCHA — not charged
- URL is malformed or exceeds 2048 characters — validation error returned
- Network timeout reaching target site — not charged
- Payment failure via x402 — request not fulfilled

## How this service works

Paid services for AI agents over x402 on Base and MPP on Tempo. Inferrail Web Read: one public web page as clean markdown, $0.002 per delivered page, refusals and target-site errors never charged, a retry never pays twice. Inferrail Hosted: one dollar budget shared by every agent and process using a workspace key (250 governed runs a month free, then $0.001/run in x402 credits).

## Output

Returns a JSON object containing the original URL, the final URL after redirects, the page title, the full page content rendered as clean markdown, a word count, a SHA256 hash of the content for deduplication, the fetch timestamp, and a receipt with the price paid, your request_id echo, and a payment reference. Refusals and target-site errors are not charged.
