Browser Session

Loads a URL in a real headless browser with JavaScript executed, then returns the rendered HTML and page title, or a base64 screenshot.

Overview

Loads a URL in a real headless browser with JavaScript executed, then returns the rendered HTML and page title, or a base64 screenshot. For pages a plain HTTP fetch can't read because the content is built client-side. Use it as a headless browser render API, JavaScript page renderer, dynamic page renderer, full-page screenshot API, or to scrape JS-heavy sites and get the post-JavaScript DOM.

How to call it

Requests are paid per call over the x402 protocol. Call the endpoint, receive a 402 Payment Required quote, then repeat the request with the signed payment header. The SDKs do both steps for you.

# 1. Ask for a quote
curl -i -X POST https://api.jarvisclaw.ai/v1/marketplace/api/browser-session \
  -H 'Content-Type: application/json' \
  -d '{}'

# 2. Pay it (the SDK signs and retries for you)
curl -X POST https://api.jarvisclaw.ai/v1/marketplace/api/browser-session \
  -H 'Content-Type: application/json' \
  -H 'X-PAYMENT: <signed-payload>' \
  -d '{}'
