Assessment: 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.

- Probe metrics: not measured yet (probes haven't run)
- Surface graded: The public REST API at https://api.hyperbrowser.ai (OpenAPI 3.0.1, 87 paths, 91 operations) with its Node and Python SDKs. The stdio MCP server is noted but stale
- Browser control: CDP over `wsEndpoint` for Playwright and Puppeteer, a WebDriver endpoint for Selenium, a computer action endpoint for mouse, keyboard and screenshots, and a live view URL
- Free tier: 5,000 credits ($5 at $0.001 a credit), 1 concurrent browser, 7 days of data retention, no card per the pricing page. Proxies and CAPTCHA solving need a paid plan
- Plans: Startup $30 a month with 30,000 credits and 25 concurrent browsers. Scale $100 with 100,000 credits and 100 concurrent. Enterprise custom with 1,000+ concurrent. Purchased credits expire after 12 months
- Rate limits: Concurrent browsers per plan, 1, 25, 100 and 1,000+. The pricing page says paid plans have no rate limits. No requests-per-minute numbers found. 429 documented on batch scrape and on x402 session capacity
- Machine payment: x402 version 2, exact scheme, USDC on Base (eip155:8453) and Solana, on sessions, Fetch and Search. Scrape, Crawl, Extract, agent tasks and sandboxes need an API key
- MCP server: Official, stdio, `npx hyperbrowser-mcp`, 10 tools, MIT. npm 1.0.25 of 13 April 2025, pinned to SDK ^0.48.1. Not in the official MCP registry
- SDKs: @hyperbrowser/sdk 1.1.0 (Node 20.20.2 or later) and hyperbrowser 1.10.0 on PyPI (Python 3.8 or later), both MIT. HyperAgent, the agent framework, is AGPL-3.0
- Regions: us-central, us-east, us-west and europe-west on all plans, asia-south on Enterprise and Select plans. Production data is hosted in the United States per the security page
- Recording: rrweb session recording is on by default, MP4 video recording is optional. Retention is 7 days on Free, 30 on Startup and Scale, 180+ on Enterprise
- Certifications: SOC 2 Type 1 report on request and annual third-party penetration tests per the trust centre and security page. The Enterprise plan card lists HIPAA and SOC 2
- Prices: Browser session $0.10 per browser-hour; Browser session by x402 $0.10 per browser-hour; Proxy traffic $10 per GB of traffic; Fetch $1 per 1,000 requests; Fetch with proxy $10 per 1,000 requests; Search $5 per 1,000 requests; Search with location $10 per 1,000 requests; Scrape $1 per 1,000 pages; Scrape with proxy $10 per 1,000 pages; HyperAgent or Browser Use step $0.02 per call; Sandbox vCPU $0.045 per vCPU-hour; Credit $0.001 per credit; Startup plan $30 per month (plan); Scale plan $100 per month (plan)

## Before you call it

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

## Connect

```bash
npm install @hyperbrowser/sdk
```

```bash
curl -X POST https://api.hyperbrowser.ai/api/session -H "x-api-key: YOUR_API_KEY" -H "Content-Type: application/json" -d '{"timeoutMinutes": 15}'
```

x402:

```bash
curl -i https://api.hyperbrowser.ai/x402/session -H "Content-Type: application/json" -d '{"timeoutMinutes": 5}'
```
