- [Reddit MCP: let an AI agent read and post on Reddit](https://scalebrowser.net/blog/reddit-mcp.md): Three ways an AI agent reads Reddit through MCP, what the Data API costs, and what a signed-in browser read in our run of 10 threads on 11 October 2026.
- [Reddit monitoring: 125 posts, 7 matches, 1 worth answering](https://scalebrowser.net/blog/reddit-monitoring.md): Which Reddit monitoring tools are left in 2026, how an AI agent watches five subreddits and reads each match, and what two rounds on 11 October 2026 found.
- [Suno API: behind a sign-in, so how do agents make songs?](https://scalebrowser.net/blog/suno-api.md): Suno shows an API sign-in page and no public docs. What unofficial wrappers do, and how an AI agent makes songs on the Suno website, measured on 11 October 2026.
- [X API pricing in 2026: 10,000 post reads now cost 50 USD](https://scalebrowser.net/blog/x-api-pricing.md): What the X API costs in 2026: 0.005 USD per post read, 0.015 to create one, a 3 million read cap, and what a logged-out browser agent reads for nothing.
- [X MCP: let an AI agent research and post on X](https://scalebrowser.net/blog/x-mcp.md): How an AI agent searches, reads and posts on X through an MCP server: the paid API at 0.005 USD per read, xAI's X Search, or a browser signed in to you.
- [Can an automated browser sign in with a passkey?](https://scalebrowser.net/blog/passkeys-automation.md): How an automated browser signs in with a passkey: what real machines answer, what Chrome's virtual authenticator gives away, and why the time has to vary.
- [PerimeterX press and hold: 2 presses, 1 call](https://scalebrowser.net/blog/perimeterx-press-and-hold.md): How the HUMAN (PerimeterX) press and hold works, why one long press fails, and how an AI agent passed it on Microsoft's sign-up in 3 runs on 4 August 2026.
- [How does Cloudflare bot management detect an agent?](https://scalebrowser.net/blog/cloudflare-bot-detection.md): What Cloudflare's bot management reads before it challenges a browser: the 1 to 99 score, JA4, JavaScript detections, behaviour, and what stealth plugins miss.
- [DataDome detection: 1 header turned a block into a login](https://scalebrowser.net/blog/datadome-detection.md): What DataDome reacted to on PayPal in 4 runs on 12 August 2026: one Accept-Language header decided captcha or login, while the block page blamed the IP.
- [Chromium fork for automation: 29 patches instead of a script](https://scalebrowser.net/blog/chromium-fork.md): Why hiding automation takes a patched Chromium rather than a script, and what a fork costs to keep: releases every two weeks, rebased patches, signing, rollback.
- [browser-use alternative: 1 identity per profile](https://scalebrowser.net/blog/browser-use-alternative.md): browser-use compared with a fixed identity per profile: what Browser Use Cloud randomises per session, what a profile keeps, and 5 USD per GB of proxy traffic.
- [Audio captcha: transcribed locally in 1.3 seconds](https://scalebrowser.net/blog/audio-captcha.md): How an AI agent answers the audio captcha of reCAPTCHA v2 on its own machine: a local Whisper tiny model, 1.3 seconds, no speech service and no model shipped.
