Extract

by Agent Web-Access in Search & web

x402 APIPassing, checked 8 min ago

Targeted web scrape: pass a CSS selector and get back only the matching elements from a fully JavaScript-rendered page. Each element returns its tag, text content and every HTML attribute. Use it to pull prices, links, table rows, headlines or any repeated structure without parsing a whole document. Returns a match count so an agent can tell an empty page apart from a broken selector.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.002.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://web.cyberwarex.com/extract?selector=h1&url=https%3A%2F%2Fexample.com'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - 'https://web.cyberwarex.com/extract?selector=h1&url=https%3A%2F%2Fexample.com' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
