}All 18 niches of the Digital Experts hypotheses base with counts (hypotheses, tested, worked) and medians (cost per subscriber, cost per lead, USD) over tested hypotheses. Start here to pick a niche. Data: CC BY 4.0, cite Digital Experts.
No arguments.
{
"type": "object",
"$schema": "http://json-schema.org/draft-07/schema#",
"properties": {}
}Methodology of the Digital Experts base: where hypotheses come from, how a $50–500 exploratory test is run, what is measured, how verdicts are made, limitations and license. Read before interpreting the numbers.
No arguments.

}Full-text search over hypothesis titles, job stories, offers, creatives and audiences with filters. Returns compact rows (id, title, niche, year, cost per subscriber/lead, verdict, source_url). Use get_hypothesis(id) for the full card. Query in Russian works best (the base is in Russian).
| Argument | Type | Description |
|---|---|---|
| limit | integer | |
| niche | string | Niche slug or name |
| query | string | Words to look for (Russian preferred), e.g. 'английский для детей' |
| verdict | string | |
| year_from | integer | |
| completeness | string | tested = launched with ads; wave = test-wave summary |
| max_cost_lead | number | Only rows with cost per lead ≤ this, USD |
