Radio Browser

Radio Browser is a free, community-driven directory of internet radio stations. The project publishes a public REST API exposing the full catalog of stations along with category aggregates (countries, states, languages, tags, codecs), click counting, voting, and station submission. Mirrors are discovered through a round-robin DNS pool (all.api.radio-browser.info) and the canonical server software (radiobrowser-api-rust) is released under AGPL-3.0, so anyone can self-host an additional mirror.

agent aware

Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.

Kin Score

API Evangelist profiles Radio Browser the way a machine reads it — 40 machine-readable artifacts across 4 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.

Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Radio Browser scores 46.6/100 (developing), with a separate agent-readiness read of 39/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Radio Browser

Each block below is one kind of artifact we hold for Radio Browser. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

APIs 4

Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Individual APIs this provider publishes, each with its own machine-readable definition.

Radio Browser Categories API

Aggregated counts of countries, languages, tags, codecs, and states.

Radio Browser Interactions API

Click counting, voting, and station submission.

Radio Browser Service API

Server stats, mirror discovery, and configuration.

Radio Browser Stations API

Browse, search, and list radio stations.

Open Collections 1

Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.

Open, tool-agnostic API collections (OpenAPI-derived and Bruno).

OPEN COLLECTION

Pricing Plans 1

Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.

Published pricing tiers and plan structures.

Rate Limits 1

Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.

Documented rate limits and quota policies.

Features 8

The notable capabilities this provider advertises, captured as structured features so they can be searched and compared instead of read one landing page at a time.

Notable capabilities this provider offers.

Round-Robin Mirror Pool

Servers discovered via DNS resolution of all.api.radio-browser.info; clients pick a healthy mirror and fall back as needed.

Multiple Response Formats

JSON, XML, CSV, M3U, PLS, XSPF, and TTL output for nearly every read endpoint.

Faceted Browse

List stations by country, country code, state, language, tag, or codec with station counts per facet.

Continuous Stream Health Checks

Stations are automatically pinged to verify their stream is reachable; results power lastcheckok and broken-station endpoints.

Community Curation

Anyone can submit a station via POST /json/add; clicks and votes feed station popularity rankings.

Open Source Server (AGPL-3.0)

The radiobrowser-api-rust server is open source; operators can self-host an additional mirror.

Geo Coordinates

Stations carry optional geo_lat/geo_long for map-based discovery.

Prometheus Metrics

Each mirror exposes /metrics in Prometheus exposition format for operational observability.

Semantic Vocabularies 1

JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.

JSON Schema 3

Standalone JSON Schema definitions describe the data models behind the API. We profile them so the shapes are validatable on their own — useful long after a single request is forgotten.

Examples 3

Real request and response payloads are what turn a spec from abstract into obvious — and they're one of the twelve things an agent needs to call an API correctly on the first try.

Example request and response payloads for these APIs.

Security Posture 1

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

Agentic Access 1

An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
