Listen Notes runs the largest podcast search engine and database, and exposes it as the Listen API - a simple, no-nonsense podcast search, directory, and insights REST API. It lets developers full-text search millions of podcasts and episodes by people, places, and topics; fetch podcast and episode metadata; browse best-podcasts charts, curated lists, and genres; retrieve podcast/episode recommendations; power typeahead autocomplete; and pull audience demographics and publisher-domain insights. The API is served at https://listen-api.listennotes.com/api/v2 and authenticated with an X-ListenAPI-Key header, with FREE, PRO, and ENTERPRISE plans billed on a request basis.
Listen Notes publishes 6 API contracts indexed on the APIs.io network, including Insights API, Playlist API, Podcaster API, and 3 more. Tagged areas include Podcasts, Podcast Search, Podcast Directory, Search, and Audio.
The Listen Notes catalog on APIs.io includes 1 event-driven AsyncAPI specification, 1 JSON-LD context, and 1 Spectral governance ruleset.
Listen Notes’ developer surface includes support, pricing, engineering blog, authentication, documentation, and 34 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Horizontal (data, software, accessibility, platform) regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it
carries 10 points of the composite. It is scored from the published contracts
themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already
holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in
front of it, and the first time that check is skipped a duplicate record is created.
Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet,
not penalised by it.
The six quality facets above are damped to 75 points between them,
because the conditional facet above carries the other
25. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 75% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/listennotes: open an issue to ask a question, or submit a pull request to add artifacts.

Registered MCP server and declares compatibility are report only — not weighted.
Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
