How this service works
Clean web reads and structured intelligence feeds for AI agents. Free plan included — 1,000 credits a month, no credit card required. Eighteen live Signals. Pay by card on a monthly plan, or per-call in USDC by crypto wallet.
Output
Returns a JSON object with a 'data' field containing structured extraction results matching any provided schema (e.g. product name, price), and a 'source' object with the original URL, final redirected URL, size of the markdown in bytes, and whether the result was served from cache.
Example use cases
Extract product listings from competitor sites
“Check out these product URLs from our competitors and extract the product name, price, and availability status for each one as structured data so I can compare them against our catalog.”
Convert research articles to agent-readable format
“I need you to read through several research paper URLs and convert them to clean markdown format, then pull out the abstract, authors, publication date, and key findings into a structured JSON so we can organize them by topic.”
Monitor e-commerce pages for pricing changes
“Go through this list of product page URLs and extract the current price, discount percentage, and stock status from each one as structured fields so I can track how our competitor pricing is changing over time.”
Technical details
Endpoint
POSThttps://skim402.com/api/v2/extract?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to read or extract structured data from any arbitrary web URL without setting up API keys or subscriptions. Ideal for pay-per-use agent workflows where the agent autonomously pays $0.015 USDC per call via x402 on Base. Best when you want both clean markdown (for LLM consumption) and optional schema-driven structured extraction in a single call.
Side effects
- URL is unreachable or returns non-200 status — extraction fails with an error
- Paywalled or bot-blocked pages may return incomplete or no content
- Payment not received or insufficient USDC — x402 payment required error returned
- Invalid or malformed URL input — validation error returned
- Schema mismatch — structured extraction may return nulls if page doesn't contain expected fields
