What the company actually does

Why this matters. Everything else in this course is a detail of this one sentence. If you cannot say what the company does in a breath, every later answer you give will be approximately right and quietly wrong. Foundation: Which exchanges run the world's trading?

We sell the record of what markets did, as an API. Prices, the numbers companies publish about themselves, the calendar of what is coming, and the context around all three. Someone else builds the app; we are the raw material underneath it.

The legal name is Unicorn Data Services, registered in Lyon, France. The product trades under the EODHD brand. Both matter: a client asking who they are contracting with is asking a real question, and the answer is not the brand.

The shelf, in one glance

Thirteen families of data, which the next unit walks through properly. The shape of it: prices at every resolution from thirty years of daily history down to a live stream, the numbers companies report, the calendar of earnings and dividends, the wider economy, and everything that is neither price nor filing — options, currencies, commodities, crypto, news and its sentiment.

The coverage figures

60+ exchanges · 150,000+ tickers · 20,000+ ETFs · 600+ indices · 1,100+ forex pairs, with an end-of-day archive reaching back 30+ years — the archive's depth, not a floor under every ticker, since an instrument's history begins at its listing.

Know them, and know they are a floor rather than a boast. The useful move when someone asks "do you have X" is not to recite the five numbers, it is to check. This course ends with a lesson on exactly how to check.

What sits around the data

The data alone would be unusable, so three things sit around it: documentation that says what each endpoint returns, an academy of use-case articles that says what to do with it, and a marketplace where partners sell datasets we did not build. All three come back later in this course.

Try it now

1. Say what the company does in one sentence, out loud, without using the word "data" twice.
2. Now make the product happen once, so the sentence stops being abstract. The smallest complete request we sell is /eod/AAPL.US?from=2026-08-01&fmt=json — one path, one symbol, one date bound. Every row that comes back is a day of a market, and that is the whole business in one response.

3. Change the ticker to a company a client of yours cares about. The Terminal opens on Apple; type the other symbol, with its exchange suffix, into its search. If it answers with a price history, you have just checked coverage the only way that is ever reliable.

4. Read the coverage claim the same way, against the source rather than from memory. /exchanges-list returns every venue we carry, with its Code, Name, Country and Currency. Its first row is below, then its last seven. The list had 70 rows on 2026-09-01 and still 70 on 2026-09-28, of which 65 are venues and five are the virtual codes MONEY, EUFUND, GBOND, CC and FOREX. That 65 is what the "60+" above is a floor under — the row count is higher than the venue count, which is exactly why the headline is not seventy-something. Now you have seen it rather than repeated it.
