Suno doesn't publish an official API, so every way to call it programmatically runs through a third party. We checked the third-party names most commonly cited for Suno access directly this session, and it turns out they resolve to two companies, not three or four, and only one of the two still offers Suno at all.
The honest finding: the two provider networks checked here are really just two companies, and only one still offers Suno
PiAPI and GoAPI are the same company operating under two brand names. Neither currently offers Suno access. PiAPI's music lineup covers Udio (branded as its "Song API"), DiffRhythm, MMAudio, and Ace Step, but Suno isn't among them. GoAPI's own live page states directly: "The Suno API (unofficial) integration on GoAPI is no longer available," and points visitors to a third-party site instead.
Kie.ai and sunoapi.org are also the same company operating under two brand names (confirmed this session by shared blog content and shared CDN assets under file.aiquickdraw.com), and this is the pair that's still live for Suno access today, alongside Apiframe.
So of the four names circulating as "Suno API providers," there are really only two distinct companies behind them, and one of the two has already exited Suno entirely.
Quick comparison
| Provider | Per-generation cost | Model versions | Follow-up actions |
|---|---|---|---|
| Apiframe (pay-as-you-go) | $0.11 | V4, V4_5, V4_5ALL, V4_5PLUS, V5, V5_5 | Extend, cover, add vocals, stems (11 credits each) |
| Apiframe (Growth-plan effective) | ~$0.042 | Same as above | Same as above |
| Kie.ai / sunoapi.org | $0.06 | V3.5, V4, V4.5, V4.5PLUS, V5 (per Kie.ai's own model page) | Extend, cover, add vocals, stems, replace section, mashup, and more |
| PiAPI / GoAPI (one company) | No Suno API offered | Discontinued | N/A |
Apiframe
Suno on Apiframe runs through the same API key and billing as every other model on the platform, images, video, and music together, rather than a Suno-specific account. Every action (generate, extend, cover, add vocals, stems) costs a flat 11 credits, $0.11 at the pay-as-you-go top-up rate ($0.01/credit), or about $0.042 at the Growth-plan effective rate ($0.00383/credit, from a $199/mo plan with 52,000 credits). Each generate request returns 2 tracks, so the effective per-track cost works out to roughly $0.055 or $0.021 depending on plan tier. Six model versions are available through a single parameter rather than separate model IDs, covered in full in the Suno Versions Explained piece. Full parameter reference is in the Suno API Guide and the docs.
Kie.ai / sunoapi.org
Kie.ai and sunoapi.org share infrastructure (confirmed by shared blog content and shared CDN assets this session) but present themselves as separate products. Between the two, sunoapi.org publishes clearer credit pricing: $5 for 1,000 credits ($0.005/credit) at its base tier, scaling to $1,250 for 275,000 credits (roughly $0.00455/credit) at its highest published tier with a 10% bonus. Kie.ai's own interactive Suno tool page shows credit costs for several follow-up actions (upload-and-extend at 12 credits, stem separation at 10, replace section at 5, music video creation at 4, timestamped lyrics at 0.5, WAV conversion at 0.4), assuming the same per-credit rate as its sunoapi.org sibling, though this wasn't independently confirmed on Kie.ai's own pricing page, which did not render static pricing content when checked this session. Kie.ai's model page lists model versions V3.5 through V5, plus a wider set of follow-up actions than we found documented elsewhere, including persona generation, music mashups, and MIDI extraction from separated stems.
PiAPI and GoAPI
PiAPI and GoAPI are one company under two brand names, and neither currently offers Suno access. PiAPI's music APIs cover Udio and a handful of other models. GoAPI's Suno integration, once offered as an unofficial pay-per-use or bring-your-own-account service, has been discontinued; its own page redirects visitors elsewhere. Since both names trace back to one company, this is a single exit from Suno, not two separate providers dropping out independently.
FAQ
Is there an official Suno API?
No. Suno does not publish one. Every provider covered here, including Apiframe, is a third-party wrapper.
Does GoAPI still offer Suno access?
No, as of this check GoAPI's own page states its Suno integration is discontinued.
Does PiAPI offer a Suno API?
No, PiAPI's music APIs cover Udio and several other models, not Suno.
Are Kie.ai and sunoapi.org different companies?
They present as separate branded products but share backend infrastructure, confirmed by identical blog content and shared CDN assets.
Are PiAPI and GoAPI the same company?
Yes, they operate as two brand names for the same company. Neither currently offers Suno access.
What does Apiframe charge per Suno generation?
A flat 11 credits regardless of action, $0.11 at the pay-as-you-go rate or about $0.042 at the Growth-plan effective rate, for 2 tracks per request.
Why isn't there a clear cheapest-overall answer here?
Kie.ai's base generation cost wasn't published in the static pages checked this session, so a direct dollar-for-dollar comparison against Apiframe's confirmed rate isn't possible without further verification.
