How this service works
x402-native paid API tools for DeFi yields, protocol TVL, AI pricing, paid MCP calls, and web scraping.
Output
A JSON object containing the extracted content matched by the provided CSS selector on the target URL — typically text, HTML, or attribute values from the selected element(s). The response structure is flexible and may include the raw extracted string and metadata about the match.
Example use cases
Extract DeFi yield from protocol page
“Pull the current APY rate from https://app.aave.com/markets using the selector '.apy-value' so I can compare it with other protocols.”
Monitor token price on exchange site
“Scrape the current price of ETH from https://coinmarketcap.com/currencies/ethereum/ using the selector '.priceValue' — I want to know what it says right now.”
Extract article headline for research
“Get the headline text from https://decrypt.co/latest using the selector 'h1.article-title' and return up to 500 characters.”
Technical details
Endpoint
POSThttps://api.400860.xyz/v1/scrape/extractWhen to prefer
Choose this endpoint when you need to extract a specific element from a public webpage by CSS selector and want to pay per-call with no subscription. It is well-suited for agent workflows that need lightweight, targeted extraction rather than full-page crawls, especially in DeFi or Web3 contexts where x402 micropayment rails are already in use.
Side effects
- Selector matches nothing on the page — returns empty result or error
- Target URL is unreachable or returns a non-200 status — request fails
- JavaScript-rendered content not accessible — static scraper may miss dynamic elements
- maxLength truncates content unexpectedly if set too low
- Rate limiting or bot protection on target site blocks the fetch
- Invalid CSS selector syntax causes a parsing error
