Endpoint
api.kadec0.xyz/v1/topic-search
Field and topic search for research papers. Give a broad field name or short phrase (like 'crispr' or 'exercise science') and get a coherent, taxonomy-grounded seed cluster: the field is resolved against the OpenAlex topics taxonomy, then the cluster returns the top-cited plus recent-influential works, each with title, authors, year, venue, citation count, and DOI. Solves the broad-term entry problem dense semantic search fails on. Keyless.
Score
The score is built from observations we collect ourselves: how the endpoint responds, what the envelope contains, how stable the price and the recipient are, who pays and how often. It is deterministic — the same input always produces the same result.
We do not publish the exact methodology yet. If you own this endpoint, write to us and we will show you, item by item, what drags the score down.

Is this your endpoint?
The score is built only from public observations. If something we recorded is wrong — say our prober hit you during maintenance — write to us. We will recheck and publish your reply next to the score.
We do not delete accurate observations. The prober makes at most one request per second per host and only asks for the payment challenge — it never pays and never takes content.
