No. APIXO’s product-facing title remains “Suno V5,” but the suno route currently exposes V5_5, V5, V4_5, V4_5ALL, V4_5PLUS, and V4. It is best described as a multi-version Suno music API.
Text to MusicVocal / InstrumentalMulti-Version API
Suno on APIXO is a multi-version music-generation route for creating vocal or instrumental tracks from a short concept or custom lyrics. Select V5.5, V5, or a V4.x backend, shape the musical direction with structured controls, and receive up to two MP3 variants with cover artwork per accepted generation.

Capabilities
Flexible song creation across multiple Suno generations
Complete Song Generation
Build a full musical concept from text rather than assembling separate vocals, instruments, and arrangements. Results can vary in structure, duration, lyric delivery, and mix.
Selectable Model Versions
APIXO exposes V5_5, V5, V4_5, V4_5ALL, V4_5PLUS, and V4, allowing applications to select a backend instead of treating the route as V5-only.
Custom Lyrics Structure
Custom mode accepts supplied lyrics alongside a title and style description. Section labels such as [Verse], [Chorus], and [Bridge] can organize the requested song structure.
Vocal or Instrumental Output
The same route supports songs with generated vocals or instrumental-only music. Instrumental generation is available through the required instrumental setting in either creation workflow.
Style and Experimentation Controls
Custom mode provides style adherence, weirdness, negative tags, audio weighting, and a best-effort vocal-timbre preference for shaping different interpretations of the same musical brief.
Two Creative Variants
One accepted generation can return two track objects, each containing an MP3 URL and cover-image URL, so teams can evaluate alternative arrangements or performances from one request.
Creation Workflows
Start with a concept or supply the song structure
Prompt-Only Song Generation
Set `customMode` to `false` and provide a `prompt` of 1–500 characters describing the intended song. Suno develops the lyrics and musical arrangement when vocals are enabled, or creates music without vocals when `instrumental` is `true`.
Prompt Only
Custom Lyrics and Style Generation
Set customMode to true, then provide a title, style, and lyrics when generating vocals. Custom mode also unlocks negative tags, style adherence, experimentation, audio weighting, and vocal-timbre controls.

Notes & FAQ
Operational guidance for APIXO’s Suno route
Integration Notes
01
The product page is titled “Suno V5,” but the live route is multi-version and currently includes V5_5 as its newest selectable backend.
02
Suno released v5 on September 23, 2025 and v5.5 on March 26, 2026; v5.5-specific improvements apply only when V5_5 is selected.
03
APIXO documents V4 custom lyrics up to 3,000 characters and V4.5, V5, and V5.5-family custom lyrics up to 5,000 characters.
04
Custom styles support up to 200 characters on V4 and 1,000 on later selectable backends; APIXO documents titles up to 80 characters and negative tags up to 200 characters.
05
Typical generation takes 60–90 seconds; APIXO recommends the first poll after 45 seconds and subsequent polling every 5–10 seconds.
06
APIXO’s detailed route documentation uses `prompt` as the required text field in both simple and custom modes. The model-page form currently displays `songDescription` for prompt-only creation, but integrations should follow the detailed documentation unless the API reference is updated.
Frequently Asked Questions
styleWeight, weirdnessConstraint, and audioWeight accept values from 0 to 1. Style weight increases adherence to the style description, higher weirdness encourages experimentation, and audio weight balances audio fidelity with lyrical control. APIXO does not publish route-wide defaults.
APIXO states that an accepted generation can return two variants and shows one resultUrls array containing two track objects. Applications should still parse the returned array rather than assume both tracks always complete successfully.
APIXO’s detailed route documentation lists $0.12 per generation, including the returned variants, rather than $0.12 for each track. It explicitly lists that rate for V5 and V5.5; separate older-backend rates and partial-result billing are not publicly itemized.
No uploaded-audio, extend, cover, remix, remaster, voice-cloning, or editing workflow is documented. Results provide MP3 and cover-image URLs, with lyrics returned when available; WAV, stems, MIDI, video, and editable project files are not exposed.
