## 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 sovereign-engine-page-extract-bada7673 -d '<json body>'
```

Example prompt: Can you extract the main content from this page for me: https://example.com/article/ai-trends-2025 — I need the article text and any key data points pulled out cleanly.

## When to prefer this

Choose this endpoint when you need to extract content from a specific web page URL in a pay-per-call, no-subscription model billed in USDC on Base via x402. It is particularly suited for AI agents that require occasional, on-demand web page extraction without committing to a monthly plan, and where crypto-native micropayment settlement is acceptable or preferred. Not ideal for JavaScript-heavy SPAs or pages requiring authentication.

## Known failure modes

- URL is inaccessible or blocked — data field may be empty with success: false
- Prompt does not contain a valid URL — extraction cannot proceed
- Network access is blocked within sandbox for non-whitelisted domains — returns empty data
- Page content is JavaScript-rendered and cannot be fetched via RSS/static fetch — partial or empty result
- x402 payment fails or USDC balance insufficient — call is rejected before execution
- Malformed prompt input — 400-level error response

## How this service works

Pay-per-call x402 execution primitives (USDC on Base). Code execution runs in isolated Cloudflare Dynamic Worker sandboxes (JavaScript + Python, network blocked). Web search backed by Bing RSS. Self-hosted facilitator.

## Output

A JSON object with a 'data' field containing the extracted page content, a 'success' boolean indicating whether extraction succeeded, and a 'receipt_id' UUID for the paid x402 transaction. Cost is $0.05 USDC per call settled on Base.
