An AI agent used the site and saw 1 of 3 claimed features working.E32E34E35E35E32E33
AI / agents: 'The credit card for the AI stack… We negotiate partnerships with AI providers to get better pricing and ca: The site describes a credit card with rewards on AI-vendor spend and links to partner pages (for example, a Firecrawl page listing 2x usage limits). Getting the card or its partner perks needs sign-in and a card application, so I couldn't check them. The site has no AI or agent feature to try.E32E34E35
A working app / platform: 'ernd's use of information received from Google APIs will adhere to the Google API Services Us: The app at app.ernd.io loads a sign-in page with 'Continue with Google' and email sign-in-link options, and the page made a GET request to /api/me. Anything past sign-in, including Google API data use, needs a login.E35
Extra observation: rewards estimator on the homepage: I moved the monthly AI bill slider from 5 to 8. The displayed monthly bill changed from $10,000 to $30,000, and the yearly estimate changed from ~$4,800 to ~$14,400.E32E33

An AI agent (claude-opus-5-5) used the site in our sandbox for 4 steps and saw 1 of 3 claimed features working. It can't connect a wallet, pay, sign or log in, so those features count as "couldn't test". What it reports is what it observed, not a verdict.

Limits
We only see what your browser sees: code and requests on a first visit, without logging in or accepting cookie banners. What the servers do with data is invisible from outside.
Site code is usually minified (compressed), so names are partly lost and some code may be only partly analysed.
Some trackers only load after you accept cookies or log in, so the real list can be longer.
We visited from a server in the United States. Sites load different trackers and cookie banners in different countries (visitors in the EU usually get a consent banner first).
The tech check compares the site's own words with what its public page loads. Work done on servers, in private code or in separate apps isn't visible here, so 'nothing found' means not visible on the public page, not that it doesn't exist.
This text was written from fixed templates because no AI writer was available. It uses exactly the same evidence.
The code reader hit its size budget on parts of 2 large bundle file(s); those parts weren't fully analysed.
Facts, not judgements: this page describes what the code and traffic show, not anyone's intent. Not financial advice. Case id xczaRx2w.

1 of 3 · What it does
Know the coin before you buy it
Paste any coin address, wallet or X post. We scan it in seconds, free, no sign-up.
Every coin gets a green, yellow or red light and a score out of 100, and every point links to its source.
2 of 3 · How to read a check
Three questions, then the money
Is the tech real? Is the dev legit? Fair launch? Each has its own score and its top reasons.
Who's behind it: the dev's linked wallets, crews that buy launches together, and the launch block by who paid for it.
Money taken out: what the dev and launch-block wallets sold or pulled in the first 24 hours.
3 of 3 · Stay on it
Track coins and wallets
Press Track on any coin or wallet. You'll get a browser notification when the dev sells, liquidity is pulled, the price moves hard, or a tracked wallet trades.
No account: it's tied to this browser. See everything you track under Tracking.
