Fansly does not publish an official public API, so there is no developer portal, no OAuth app registration, and no documented endpoints you can sign up for. Every Fansly integration you have seen is built on something unofficial. That leaves developers with two paths: scrape the website, which breaks whenever the frontend changes, or talk to the same authenticated apiv3 endpoints the Fansly apps themselves use.
CreatorAPI takes the second path and hosts it for you. It exposes the full Fansly apiv3 surface through one REST API, calling the platform's own endpoints through your connected session. Because these are the endpoints the official apps depend on, responses come back as stable, structured JSON rather than HTML you have to parse. You can read and act on messages, fans, media, earnings, posts, transactions and subscribers. The complete route list lives in the Fansly API reference.
Access works through one API key and one route pattern, and it is the same key and the same pattern CreatorAPI uses for OnlyFans. Every native call follows {METHOD} /v1/{account}/native/{path}, where {account} is the creator id you get back when you connect a Fansly account. If you later add an OnlyFans account, nothing about your integration changes except the account id.
# list a Fansly creator's subscribers through the native route
curl -H "X-API-Key: $CREATOR_API_KEY" \
"https://api.creator-api.com/v1/{account}/native/subscriptions/subscribers?limit=50"
Connecting an account is passwordless. The creator either imports an existing session or signs in inside a browser that CreatorAPI hosts, typing their password and their own 2FA code into the real Fansly login. Passwords and 2FA codes never reach CreatorAPI. Each connected account then runs on its own managed residential IP, and no two accounts of the same platform ever share one IP. You can also bring your own proxy. Sessions are isolated per account and can be revoked instantly from the dashboard.
One honest note on risk: no approach is completely risk free. Native endpoints, one residential IP per account, and no password handling minimise it, but nobody can promise zero risk on a platform without an official API.
Fan CRMs, earnings dashboards and chat tooling are three natural things to build on the Fansly API, and CreatorAPI ships first party features for each.
The Fansly API plan costs 39 USD per month and includes 24,000 credits, and you can start free with 1,000 credits and no card required. A native read costs 1 credit and a native write costs 2, so the monthly allowance covers tens of thousands of calls, and unused credits roll over up to 200 percent of the plan allowance. If you outgrow the plan, top ups start at 45 USD for 25,000 credits, and the Suite plan adds OnlyFans on the same key. Full details are on the pricing page.
Start by creating a free key, connecting a Fansly account, and making one native GET call. The free 1,000 credits are enough to explore the whole surface: list subscribers, pull earnings, read a chat thread, and register a webhook. From there the Fansly reference documents every route on the apiv3 surface, and the same integration extends to OnlyFans whenever you need it.
Start free with 1,000 credits, no card required. One key covers Fansly and OnlyFans.
