> Earn Tools Web Extractor is a paid API for AI agents from earn-tools-backend.onrender.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Fetches a public static webpage and returns clean markdown, metadata, word count, and links for agent research and RAG pipelines.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 earn-tools-web-extractor-b6dea840 -d '<json body>'
```

Example prompt: Fetch the content of https://en.wikipedia.org/wiki/Large_language_model and convert it to clean markdown with links included, keeping it under 60000 characters.

## When to prefer this

Choose this endpoint when you need cheap, fast extraction of a single public static webpage into markdown for RAG ingestion, agent research, or summarization — particularly in pay-per-call autonomous agent pipelines using x402 micropayments. Prefer it over browser-automation tools when JavaScript rendering is not required and cost matters. At $0.003 per call it is suited for high-volume document ingestion workflows.

## Known failure modes

- Non-public or paywalled URLs return an error or empty content
- Dynamic JavaScript-rendered pages may return incomplete content since only static HTML is fetched
- URLs exceeding the max_chars limit will be truncated at the specified character ceiling
- Invalid or malformed URLs return a validation error
- Pages that block scrapers via robots.txt or IP filtering may fail silently or return partial content
- Network timeouts on slow or unreachable hosts

## How this service works

Low-cost x402 pay-per-call tools for autonomous buyers. Web extraction returns static public pages as clean markdown; every payable operation declares x-payment-info and a 402 response. Free betas: Agent Purchase Guard adds retry-safe purchase intent controls; Outcome Router accepts a desired result plus max budget and autonomously discovers fulfillment, tries zero-dollar proof-of-work first, and supports buyer-signed x402 paid execution where available.

Buyer-signed paid HYDRA execution
- Outcome request: POST https://earn-tools-backend.onrender.com/outcome-router
- Paid execution: POST https://earn-tools-backend.onrender.com/outcome-router/execute/{requestId}
- First execution call returns the relayed Agent402 Smart Order Router x402 PAYMENT-REQUIRED challenge.
- An x402-capable buyer wallet signs locally and retries with PAYMENT-SIGNATURE.
- HYDRA forwards the proof and returns the routed result.
- HYDRA never receives the buyer private key or uses owner working capital.
- Current beta platform fee: $0. Higher paid tiers are not auto-escalated.

## Output

Returns a JSON object with ok status, page title, final resolved URL, full markdown body, word count, extraction mode (static_html), and an untrustedContent flag warning that the page content is attacker-controllable.
