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.\n\n## Before you call either\n\n### Browserbase\n\n1. Use x402.browserbase.com when you have a wallet and no key. Terminate the session to get unused minutes refunded\n2. Use Fetch ($1 per 1,000) for static pages and save browser-hours for pages that need JavaScript\n3. Close sessions explicitly. Each session bills at least one minute, and idle ones keep billing\n4. Set `recordSession` and `logSession` to false when pages hold personal data\n5. On 429, wait `retry-after` seconds before creating another session\n\n### Hyperbrowser\n\n1. 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\n2. Save the x402 creation response. It holds the only copy of the connection tokens, and `managementToken` is what stops the session\n3. Stop sessions explicitly in cleanup code. Browser time bills per second until the timeout\n4. Use Fetch at $0.001 a page for static pages and keep browser sessions for pages that need interaction\n5. Add `\u0026keepAlive=true` to `wsEndpoint` to reconnect after a CDP disconnect. Treat that URL as a secret because it carries the session token\n\n## Questions\n\n### Which is better for AI agents, Browserbase or Hyperbrowser?\n\nBrowserbase scores 76.2 (BB) on agent readiness against Hyperbrowser's 66.9 (B), and leads in 5 of 7 scored categories.\n\n### Do Browserbase and Hyperbrowser need an API key?\n\nBrowserbase needs an API key. Hyperbrowser takes an API key or an OAuth sign-in. An agent can also pay Browserbase per call over x402, with no account. An agent can also pay Hyperbrowser per call over x402, with no account.\n\n### Can an agent call Browserbase and Hyperbrowser without installing anything?\n\nYes. Browserbase has a hosted endpoint at https://api.browserbase.com/v1 and Hyperbrowser at https://api.hyperbrowser.ai.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/browserbase-vs-hyperbrowser.json, and with the fewest tokens: https://www.anchorterminal.com/compare/browserbase-vs-hyperbrowser.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"browserbase\", \"b\": \"hyperbrowser\"}`.
