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.

TinyFish

OpenAPI documents are published for five APIs, errors carry typed codes and request IDs, and Search and Fetch are free within daily allowances. The terms let Tiny Fish train its models on customer data, run creation takes no idempotency keys, and the status page shows an hour or more of downtime on several days for the Browser and Search APIs.

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

TinyFish

  1. Check result as well as status. A run can be COMPLETED while the goal failed, with result.status set to failure
  2. Don't retry POST /v1/automation/run blindly after a timeout. There are no idempotency keys, so list runs first to avoid duplicates
  3. Use /v1/automation/run-async or /run-sse when a run may need cancelling. Runs started with the synchronous endpoint can't be cancelled
  4. Allow 60 seconds for Browser session creation, connect Playwright to cdp_url (not base_url), and DELETE the session when done because billing is per minute
  5. Never put passwords in goal, which is logged. Pass use_vault: true with credential_item_ids, or use_profile: true for saved login state

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
