Listen Notes

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 5 API contracts indexed on the APIs.io network, including Insights API, Playlist API, Podcaster API, and 2 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 39 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/.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Data Marketplaces (data providers on cloud data platforms)	standard	29.3	-	-
Podcasting 2.0 (open podcast namespace, measurement, hosting)	standard	29.3	-	-

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.

Standards implemented 2

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
