API de Teoría Musical
Matemáticas de teoría musical como API, en temperamento igual con A4 = 440 Hz y notación de tono científica (C4 = Do central = MIDI 60). El endpoint de notas convierte libremente entre un nombre de nota (A4, C#5, Eb3), un número de nota MIDI y una frecuencia — y cuando pasas una frecuencia, devuelve la nota más cercana y cuántos cents está desafinada. El endpoint de intervalos da la distancia entre dos notas en semitonos y cents, su nombre (quinta perfecta, tercera mayor, …) y la relación de frecuencia exacta. El endpoint de acordes devuelve las notas, números MIDI y frecuencias de un acorde a partir de una nota fundamental y una calidad (mayor, menor, disminuido, aumentado, suspendido, 6, 7, maj7, m7, dim7, m7b5, 9 y más). El endpoint de escalas devuelve las notas de una escala o modo a partir de una fundamental — mayor, las tres escalas menores, los siete modos eclesiásticos, las pentatónicas mayor y menor, blues, tono completo y cromática. La ortografía con sostenidos o bemoles es seleccionable. Todo se calcula local y determinísticamente, por lo que es instantáneo y privado. Ideal para aplicaciones y juegos musicales, sintetizadores y DAWs, entrenamiento auditivo y enseñanza de teoría, afinadores y herramientas MIDI. Cálculo local puro — sin clave, sin servicio de terceros, instantáneo. En vivo, nada se almacena. 5 endpoints. Esto es teoría musical; para buscar pistas y artistas usa una API de música y para el repertorio clásico usa una API de música clásica.

Music Theory API
Music-theory maths as an API, computed locally and deterministically over the twelve-tone chromatic scale. The interval endpoint gives the number of semitones and the interval name between two notes — C to G is seven semitones, a perfect fifth. The transpose endpoint shifts one or more notes up or down by a number of semitones, so C E G transposed up seven becomes G B D and a negative value transposes down. The chord endpoint returns the notes of a chord from a root and a type — major, minor, diminished, augmented, the sevenths (major7, minor7, dominant7, diminished7, half-diminished7), sixths, suspended, add9, ninth and power chords — so C major is C E G and C7 is C E G B♭. The scale endpoint returns the notes of a scale from a root and a mode — the major and three minor scales, the seven church modes, the major and minor pentatonics, blues, whole-tone and chromatic — so C major is C D E F G A B and A natural-minor is A B C D E F G. Notes use C, C#, D♭ … B, and accidental=flat spells with flats. Everything is computed locally and deterministically, so it is instant and private. Ideal for music-education, ear-training, songwriting, DAW-plugin, notation and instrument app developers, chord-and-scale tools, and practice software. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 4 endpoints. This is pitch-class theory; for the actual frequency of a note use a music-note API.

Nostr API
Live-Profil und Notizen für jedes Nostr-Konto, direkt aus dem offenen Nostr-Relay-Netzwerk gelesen – kein Key, kein Konto, nichts gecached. Nostr ist das dezentrale, zensurresistente soziale Protokoll ohne zentralen Server, daher fragt dieser Dienst mehrere öffentliche Relays parallel ab und führt die Ergebnisse zusammen und dedupliziert sie. Geben Sie einen öffentlichen Schlüssel an, entweder als 64-stelligen Hex-String oder als npub…-Key (er dekodiert bech32-npub-Keys für Sie), und der Profil-Endpunkt gibt die kind-0-Metadaten des Kontos zurück: Name, Anzeigename, Über/Bio, Bild, Banner, Website, NIP-05-verifizierte Kennung und Lightning-Adresse – fiatjafs Key wird zu Name "fiatjaf", NIP-05 [email protected] aufgelöst. Der Notizen-Endpunkt gibt die aktuellsten kind-1-Textnotizen des Kontos zurück – die Beiträge – neueste zuerst und über Relays dedupliziert, jeweils mit Inhalt, Zeitstempel, Notiz-ID sowie Erwähnungs- und Antwortzahlen. Der Relays-Endpunkt listet die abgefragten öffentlichen Relays auf. Dies ist die Profil-und-Beiträge-Schicht für jeden Nostr-Client, Bot, Indexer oder soziales Dashboard – live aus dem Relay-Netzwerk, nichts gespeichert. Unterscheidet sich von zentralisierten Plattform-Social-APIs – dies liest das offene Nostr-Protokoll direkt von seinen Relays. 4 Endpunkte.

Programming Languages API
The language definitions GitHub uses to recognise code (the open-source Linguist data) as an API — a clean reference for syntax highlighting, file-type detection, repository dashboards and developer tooling. For each of 800+ languages the API returns its type (programming, markup, data or prose), its brand colour (the hex GitHub paints it), the file extensions associated with it, common aliases, the GitHub language id and the editor (ace) mode. Look a language up by name or alias (golang resolves to Go), reverse-look-up which language(s) own a file extension (.py → Python; .h → C, C++, Objective-C), list the languages of a type, search, or list them all. Distinct from languages-api (ISO 639 human languages) — this is the programming-language reference. Served from memory — always fast.

MIME Types API
Die kanonische MIME-/Medientyp-Datenbank (die jshttp mime-db, die von Express und dem Großteil des Node-Ökosystems verwendet wird: IANA + Apache + nginx), aus dem Speicher bereitgestellt — kein Key. Lösen Sie einen Medientyp in seine Dateierweiterungen, Zeichensatz und Komprimierbarkeit auf; suchen Sie den/die Medientyp(en) für eine Dateierweiterung (z. B. png → image/png); und listen oder durchsuchen Sie Typen nach Quelle. 2.600+ Medientypen, 1.000+ mit Dateierweiterungen. Schlankes, vorhersagbares JSON. Ideal für Upload-Validierung, Content-Type-Auflösung, Dateityperkennung, Download-Handler und Entwicklerwerkzeuge.
