compare_people

Two to five people set out side by side, line by line — how they work, how they come across, where their careers have gone, how deep their experience runs, how visible they are, who they are connected to. You get a table you can read down a column for one person or across a row to see how they differ. Tell it what the comparison is for and the framing follows: people to pitch, partners to weigh, guests or speakers to prepare for. Not a consumer report: never for deciding whether to hire, admit, lend to or house anyone. It compares people you have already looked up; if fewer than two of them are on file it says so and charges nothing. If a name matches more than one person you get the candidates for that name, also free. Costs 15 credits per comparison, whatever the number of people.

Discovered
enrich_person

How to reach one person: their email address, phone number where there is one, and their profile links. Give a name — add their employer if the name is a common one — and you get back the person, their current role, and the ways to contact them. Use it when someone says "how do I get hold of her", "find his email", "I need to reach the person who runs marketing there". Do not use it to find out WHO to contact: this looks up somebody you can already name. If the name matches more than one person you get the list of candidates and nothing is charged; pick one and ask again. Nothing is charged when nobody matches either. Costs 5 credits when it finds them. If you name a company MentionFox holds a record for, the answer starts with the MentionFox check on it: red flags found, in how many sources, with a link to the full findings.

export_report

Turn something you already have into a file you can send someone: a web page, a print-ready page you can save as a PDF, or plain text. Nothing about MentionFox appears on it, and you can put your own name, logo and colours on it, so it goes to a client as your work. Use it for "send me that as a PDF", "I need this as a document for the client", "put our branding on it". This makes a fixed copy of what exists now — for something that keeps up to date as the information changes, share the live link instead. Costs 5 credits. Plans and credits: https://mentionfox.com/pricing

Discovered
find_buyers_now

Give the website of the business you sell for. MentionFox reads it to learn what you sell, then searches recent filed events for up to 10 companies with a reason to buy from you now: new funding filings, a new chief executive, finance chief, operations chief or general counsel, IPO filings, activist stakes of 5% or more, layoff filings and state layoff notices, crowdfunding raises and new Y Combinator companies. US companies only. Investment funds and real estate filings are left out. Every result carries the record it came from (record_url, for example the SEC filing or the state notice list), so you can check it yourself; the why_now line is written from that record, and fit is a short note on why the company matches what you sell. searched_feeds lists every feed searched with the date of its newest record. Fewer than 10 means fewer were found; the list is never padded. Costs 1 credit when companies come back; a search that finds none costs nothing. The same search is free to try at https://mentionfox.com/buyers. Plans and credits: https://mentionfox.com/pricing

get_dossier

Everything on file about one person, in sections: what they have done, who they work with, how they are spoken about, what they have written or said in public, and what has been in the news about them lately. Broader than a short brief and not written for any one purpose — this is the file, not the verdict. Use it for "tell me everything about her", "what am I walking into with this person", "is this creator worth working with", "background on him before the call". If you only need an email, ask for their contact details instead — that is far cheaper. If a short written assessment is what you want, ask for a brief. If the name matches more than one person you get the candidates and nothing is charged; nothing is charged when nobody matches.Costs 30 credits the first time, and nothing at all if you have looked this person up before. If you name a company MentionFox holds a record for, the answer starts with the MentionFox check on it: red flags found, in how many sources, with a link to the full findings.

Discovered
get_full_report

The long version: a full written report on one subject, section by section, ending with the sources it drew on. Where the short brief runs to a page, this runs to several thousand words. It is fixed at the moment it is made — it records what the record said on that day and is never edited afterwards, so what you show someone in six months is what you bought. If you want a fresher picture, you ask for a new one: it is written and paid for separately and the old one stays exactly as it was. Asking again for a subject you already have a report on hands you the one you already bought, free. Writing takes a few minutes; if it is still being written when the call comes back you get a link and can return to it. Costs 50 credits and needs the Pro plan. Subject types you can ask for: accelerator (50 credits), company (50 credits), counterparty (50 credits), crypto_coin (50 credits), donor (50 credits), executive (50 credits), expert_witness (50 credits), founder (50 credits), insurance_underwriting (50 credits), investor (50 credits), journalism_person (50 credits), journalist (50 credits), litigation_funder (50 credits), nft_collection (50 credits), pe_firm (50 credits), penny_stock (50 credits), physician (50 credits), pre_ipo_secondary (50 credits), publication (50 credits), source (50 credits), spac_sponsor (50 credits), specific_fund (50 credits), vc_firm (50 credits), wealth_advisor (50 credits). For a company, put its website in company (for example subject "Flock Safety", company "flocksafety.com") and the report starts on that company straight away; a website on its own as the subject works too. If you give only a name and more than one company goes by it, nothing is charged: you get a short list of the companies it could be, each with its website and a line on what it does, and you call again with the right website in company. Use this when someone says "I need the full write-up", "proper due diligence before we commit", "the long one".

get_my_recent_research

What you have already looked up. Free: nothing is charged. Lists the people you have researched, the write-ups you have had made, and the calls you have run here recently — yours only, nobody else's. Worth calling before you pay for something: if you looked this person up last month, you already have it. Use it for "have I checked this person before", "what did I look at last week", "show me what I have". Nothing is looked up and nothing is charged. Plans and credits: https://mentionfox.com/pricing

Discovered
get_snapshot

A short brief on one subject: for a company, its red flags with sources (lawsuits, bankruptcy and SEC filings, executive departures, layoffs), who runs it and who funded it; for a person or a publication, who they are and what the record shows. It is written from what is on the record and returned as text plus a link to a formatted page you can share. Say who the subject is and what kind of subject they are, because the brief is written for the kind: what matters about a founder is not what matters about a doctor. What comes back is about a page: who they are, what the record shows, what stands out, and what to be careful of. Ask for the same subject twice and the second time is free — you are handed the brief already written, unchanged, rather than paying for it again. Nothing is charged when there is no such subject or too little on the record to say anything useful. Subject types you can ask for, and what each costs: company (5 credits), counterparty (5 credits), crypto_coin (5 credits), donor (5 credits), executive (5 credits), expert_witness (5 credits), founder (5 credits), insurance_underwriting (5 credits), investor (5 credits), journalism_person (5 credits), journalist (5 credits), litigation_funder (5 credits), nft_collection (5 credits), pe_firm (5 credits), penny_stock (5 credits), physician (10 credits), pre_ipo_secondary (5 credits), publication (5 credits), source (5 credits), spac_sponsor (5 credits), specific_fund (5 credits), vc_firm (5 credits), wealth_advisor (5 credits). Use this when someone says "who is this", "what should I know before I meet them", "quick read on this firm". For the long version, use get_full_report.

scan_for_mentions

What people said about something in the last day. Name a brand, a product, a topic or a person and this comes back with the posts, comments, articles and videos that mention it — each one with where it was said, a link to it, and whether it read as positive, negative or neither. It also marks the ones that sound like somebody about to buy, so this is the tool for "who is asking for something like ours". Use it for "what are people saying about us today", "did anyone pick up the launch", "anything new on this topic this week". It looks across 55 places by default and you can narrow that. It does not build a picture of a person — for that, ask for a brief. Costs 3 credits for each place it looks, so a default run of five places is about 15.

source_check

Someone says they are a doctor, a lawyer, a broker, a professor, a director of a company. This checks those particular claims against the official lists that would record them. Paste whatever you have — the pitch email, a name, a link — and the claims are read out of it. You get one of four answers: verified, partly verified, could not verify, or contradicted by the record. Under it: each claim that was confirmed, where it was confirmed and a link to the entry; each claim that was not, saying exactly which list was searched and came back empty; and a plain list of what was not checked at all, so a gap looks like a gap instead of a clean bill of health. It will never tell you somebody is fake. There is no such answer, because failing to find someone on a list is not evidence they are lying — plenty of real people are not on the list that would cover them, and "could not verify" means one search, on one day, in one place. What comes back is fixed at the moment it was made and never edited; checking again later produces a new one and leaves the first alone. Use it for "is this person who they say they are", "check this expert before I quote them", "should I trust this pitch", "is this doctor actually registered". Costs 25 credits and takes a few seconds.
