Verdicts

Hyperbrowser

Sessions, Fetch and Search can be bought by x402 at api.hyperbrowser.ai with USDC on Base or Solana and no account, and unit prices are public. The official MCP server was last published in April 2025, no request rate limits or SLA are published, and the privacy notice covers only the website.

Steel

The hosted API has a public OpenAPI document, per-unit prices, $30 of starting credit and x402 payment for scrape, screenshot and PDF calls. The status page records three API or session-creation incidents of more than an hour in 90 days, and the documented CDP connection puts the API key in the URL.

Before you call either

Hyperbrowser

  1. With a wallet and no key, POST to https://api.hyperbrowser.ai/x402/session and read the PAYMENT-REQUIRED header. Sessions are prepaid for 5 to 60 minutes with no refund
  2. Save the x402 creation response. It holds the only copy of the connection tokens, and managementToken is what stops the session
  3. Stop sessions explicitly in cleanup code. Browser time bills per second until the timeout
  4. Use Fetch at $0.001 a page for static pages and keep browser sessions for pages that need interaction
  5. Add &keepAlive=true to wsEndpoint to reconnect after a CDP disconnect. Treat that URL as a secret because it carries the session token

Steel

  1. Use POST /v1/scrape for pages you only need to read. It starts no session and costs $5 per 1,000 calls, or $0.01 a call by x402
  2. Release every session with POST /v1/sessions/{id}/release and set inactivityTimeout. Browser time bills by the minute, rounded up
  3. Build the CDP URL as wss://connect.steel.dev?apiKey=<key>&sessionId=<id> and keep it out of logs, because it carries the key
  4. Launch sessions end after 15 minutes at most, and timeout cannot be changed on a live session
  5. CAPTCHA solving and Steel's managed proxies on Launch need $10 of paid balance. Free credit does not count
