Dataset
Harpd Research Dataset
One record per published monthly research report: research family, the closed UTC month it covers, the report URL and the number of ranked products in scope. Every figure inside a report is derived from that month's closed rank snapshot; nothing is authored by hand.
Quick answer
What is the Harpd Research Dataset?
The Harpd Research Dataset indexes the 5 monthly research reports Harpd has published, the most recent covering 2026-08. Each record names the research family, the closed UTC month, the report URL and the number of ranked products in scope. Reports are generated from closed monthly rank snapshots — a period is written once, after it closes, and never edited — and the dataset is published as open JSON under CC BY 4.0.

What this dataset contains
One record per published monthly research report: research family, the closed UTC month it covers, the report URL and the number of ranked products in scope. Every figure inside a report is derived from that month's closed rank snapshot; nothing is authored by hand.
Scope. Published Harpd Research reports across all research families. The current release holds 5 reports and was last updated .
Harpd is an independent product discovery and ranking intelligence platform. Rank Points, where this dataset carries them, are promotional placement bought with Credits — they are not an editorial quality score, rating or review.
Fields
Every field the endpoint publishes. The list is generated from the dataset’s own schema, so a field cannot ship undocumented.
| Field | Description |
|---|---|
family | Research family slug (ai-tools-index, ai-market-index, …). |
familyTitle | Research family display title. |
monthKey | Closed UTC month the report covers (YYYY-MM). |
url | Canonical research report URL. |
listingCount | Ranked products the report covers. |
Sample record
The first record currently returned by /data/research.json. Shown so the row shape is verifiable without fetching the endpoint; the live files move, so treat this as a shape sample rather than a snapshot.
family | familyTitle | monthKey | listingCount |
|---|---|---|---|
| ai-agent-index | AI agent index | 2026-08 | 13 |
How it is generated
Every figure in a research report is derived from a closed monthly archive snapshot (/api/rank/archive/monthly/{key}), or from diffing the previous month's snapshot when the report discusses movement or new entrants. Nothing is authored by hand and no number is estimated. A page is only published when its period is closed and the family-scoped snapshot contains enough approved listings to be meaningful.
Update frequency
Monthly: a report is generated once its UTC month has closed and is never rewritten.
Each record carries its own date where the dataset provides one, so any value can be re-checked against the endpoint after the fact. The dataset’s lastUpdated field moves only when a record actually changes — never on a rebuild alone.
Access the data

No API key is required for any public dataset. Rate limits, caching and versioning for the documented endpoints are described in the API reference.
Methodology
How these numbers are produced is documented in full at harpd.com/rank/methodology/. A number in this dataset is citable only because that methodology exists and is public.
Licence
This dataset is released under CC BY 4.0. Attribution is required and no endorsement is implied. Reuse, redistribution and commercial use are permitted with attribution to Harpd.
Why it matters
Publishing this dataset as an open, machine-readable file lets researchers, developers and AI systems build on Harpd data without scraping the live site. Every record carries a data date and the whole dataset carries a CC BY 4.0 licence, so a number quoted from it is directly citable and reproducible.
Limitations
- Research measures closed monthly snapshots of the Harpd Rank board, not the live board; positions are final at month close.
- Claims in research must resolve to a registered dataset and methodology. A claim that does not is unsupported and will not be published as a fact.
- Harpd Rank Points are promotional placement, not an editorial quality score; research does not present them as a measurement of quality.
