I tested my main email account, and it found the wrong country, and in that country the wrong person (wrong name).Then I tested the email address of my boss, where it found a few fields of the company (address and business type), but not the person.Then I tried a complete bogus address and still got a "success" but without meaningful data:{ "success": true, "email": "hjd28ebsgis63kdnrzdg@gmail.com", "enrichment_data": { "entity_type": "person", "name": "Hjd", "age": null, "age_source": null, "gender": "other", "gender_source": "inferred", "city": null, "state": null, "country": null, "country_code": null, "occupation": null, "occupation_category": null, "role_seniority": null, "company": null, "company_category": null, "business_email": null, "personal_email": "hjd28ebsgis63kdnrzdg@gmail.com", "personal_phone": null, "work_phone": null, "high_school": null, "university": null, "instagram_handle": null, "instagram_followers": null, "tiktok_handle": null, "tiktok_followers": null, "twitter_handle": null, "twitter_followers": null, "youtube_handle": null, "youtube_followers": null, "linkedin_handle": null, "linkedin_followers": null, "interests": null, "interests_category": null }, "enriched_at": "2025-11-27T07:46:44.878Z", "credits_used": 0, "credits_remaining": 97, "cached": false, "request_id": "d5254e79-6f25-4fbf-b021-24539c97b636", "timestamp": "2025-11-27T07:46:44.878Z" }This tool could be useful, but right now, it isn't. Its like a LLM from 2024: looks impressive on the surface, but is not usable for daily work.

 Some work to do on precision and recall. Thanks for testing it out. Hah yes 2024 llm sounds right.I’m interested in what you think you’d use it for if you don’t mind sharing, and what you would benchmark it against.

 I would use this to determine how likely a given email address will receive my mail. I build websites, where people create accounts and an awful lot of them provide unroutable email addresses. This is annoying for me and for the users. If I could give them a warning like "this email address looks like it isnt usable, are you sure?".

 Yes the coverage is not going to be near 100% so you’d get a lot of anger with this use case. There are some libs that will check via smtp if they are likely reachable, and some services. Is “verify your email” and option ie sending an email on signup as part of the signup flow an option?

I tested with a fairly old (10+ year) gmail account and every field other than the full name came back as null which is surprising, will try a few more tests and see how i go, but that wasnt the expected result :)
- hazzadous72 days ago
  Let me know how you get on with the testing. And if you have a use case let me know and i can look at optimising for it

Cool. I was actually just searching for something like this that was quick to get started. Do you support social url for data query?
- hazzadous74 days ago
  Thanks Ryan! It only supports query by email at the moment but if you can explain the social url use case and the atteibutes you’d want to retrieve I’ll see what’s possible.

It worked well when I looked up the email associated with my resume website. Not as much for less public people I know.
- hazzadous72 days ago
  Yes this is open source intel based so does struggle on that. Do you have a specific use case in mind?
N_Lens72 days ago
Same experience as others here - shows nulls on most fields even for my commonly used, public facing email addresses.
- hazzadous72 days ago
  Hmm surprising you’re not getting anything for public emails. Hit rates can be low but not expected in those cases. Are you using anything else currently for the same task

You may want to think about allowing the hash of the email to be sent so that PII isn't being transported.
- hazzadous72 days ago
  It’s doing real time research so might be a bit tricky with a hash. Can you see a way around that?

hit the curl. ~800ms TTFB.if this is truly "real-time" and not a cached graph, how do you handle rate limiting and CAPTCHAs at scale? Even with "public" data, on-demand scraping usually requires massive residential proxy rotation which eats that $0.03 margin alive.
- hazzadous74 days ago
 thanks for giving it a go!if you tried the curl command then yes this is indeed fast. the example curl command is hardcoded, john.smith@example.com is used with a static response for the purposes of allowing users to test the shape of the api without needing to be authed. low time to first test was my aim.keen to hear if you have a use case for something like this?

Tried it on two addresses, everything was null. All it did was infer I was male from my name.
- hazzadous72 days ago
  Hah some high value info right there. Thanks for trying it out.

Too slow and most of the fields are null, doesnt work basically
- hazzadous72 days ago
  Do you have an idea of what would be fast enough and what use case you’d need it for. Definitely not peak recall right now for sure.
hazzadous72 days ago
let me know what use cases you have. i can update a tweak accordingly if it makes sense. anything goes. almost anything. nothing illegal.thanks for the feedback

what would be the difference of this vs using an API like Apollo?
- hazzadous72 days ago
  Pretty similar except maybe you’ll get lots more nulls judging by the other comments! Cheaper but nulls. Will need to work on the recall a bit. But also potentially based on use case feedback maybe look at other niches and features
