OnlyFansAPI Review: Deep Coverage, Shaky Fine Print

OnlyFans has no official API, and the vendor's FAQ says as much: "No, OnlyFans does not offer a public official API." OnlyFansAPI works from the outside, and its published reference runs deep, with Fansly and Fanvue documented in their own sections. The pricing cards also list no-code modules for Zapier and Make, and an MCP server, so you don't have to start from raw HTTP.

The vendor can't settle on how big it is, though. The pricing cards and the docs landing page quote different endpoint counts, and the docs themselves publish fewer than either, one endpoint per reference page.

The vendor's Free plan card calls it "Honestly useless... but, perfect for trying OnlyFans API out." The request limit bears out the first half. On the paid plans, the price you sign up at can move. The Pro volume discount sits under a fair-use clause that lets the vendor go back to the full per-account rate if it decides your use isn't fair, and the add-ons are priced off each account's earnings the month before, so a creator's good month shows up on your next bill. Even the trial needs a live account, since the homepage FAQ says it "activates automatically" once real accounts are connected.

The refund promise is where the pitch and the paperwork split. The pricing page header invites you to try it risk-free with a money-back guarantee. The terms say "All fees are non-refundable" and "We do not refund for non-usage, partial periods, or change of mind." The one exception the terms name is a critical failure the vendor doesn't fix within a set window after you report it. The guarantee doesn't appear anywhere in the terms. Treat it as marketing copy until it's in the contract.

Uptime holds up better. The homepage advertises an SLA uptime figure, but the terms only set a lower monthly target and say the vendor does "not warrant uninterrupted" operation, so nothing in the contract backs the homepage number. The public status page earns some trust back, though. It shows uptime bars and response-time charts for the API and the console, bad days included, and when we checked, the API's trailing figure sat just under the homepage claim.

How it connects matters more than any of that. The vendor says accounts link through its own login flow, which handles the password, two-factor codes and face verification, and on the paid plans each account runs behind a dedicated mobile proxy (Pro customers can bring their own). If a platform restricts or bans an account, the terms leave that with you, lost earnings included. There's no sandbox, either. The docs tell you to test by creating a new OnlyFans account and connecting it, so your first call goes against a real account. Reselling and white-labelling are allowed, which helps if you're building for other agencies, but the account risk travels with it.

That's why the ban record is the claim to check, and the homepage stretches it. It claims a ban-free run longer than OnlyFansAPI has existed. The about page says the FansMetrics team launched the product the year after FansMetrics was acquired, so the record only adds up if you count the FansMetrics years. For an unofficial API, that's the worst claim to inflate.

Fansly and Fanvue support is what the vendor documents, and on Fanvue it contradicts itself. The homepage lists Fanvue as coming soon, but the docs already publish a Fanvue reference.

Buy OnlyFansAPI if you want one API across OnlyFans and Fansly and you're prepared to carry the account risk yourself. Skip it if you can't put a real account on the line just to evaluate it, or if the money-back promise is part of why you'd sign up.
