The cheapest and fastest OnlyFans API

The Only API is the most comprehensive and affordable OnlyFans API on the market. We provide 200+ endpoints covering messaging, content, earnings, subscribers, campaigns, and payouts. Unlike competitors, we charge a simple per-account fee with unlimited API calls and zero credits. Built specifically for agencies and developers.

Slot-based: $20/month per OnlyFans account slot. Once you reach 15 slots, ALL your slots drop to $15/month — not just the new ones. Stripe handles the volume tier automatically, so the discount kicks in the moment you cross 15. Every paid slot includes unlimited API calls. There is also a free tier with 1 account and 1,000 API calls/month so you can test before paying.

A slot is a 30-day right to keep one OnlyFans account connected. When you add a new account, a new slot is created on your subscription and you are charged prorated for the rest of the current period. If you disconnect that account, the slot stays paid until renewal — you can attach a different account to the same slot, no extra charge. Releasing a slot stops billing for it at the next renewal.

No. Once you have a paid slot, API calls on that slot are unlimited. The free tier is the only place with a per-month call cap (1,000/mo), to keep abuse off the free plan.

As many as you need. Each connected account uses one slot. Buy a slot, connect an account; remove a slot, drop the bill at renewal. Perfect for agencies managing anywhere from 5 to 500+ creators. Each account gets its own proxy routing and session management.

Yes. Every plan starts with a 14-day free trial — full access to all 200+ endpoints, no usage caps. Cancel anytime before the trial ends and your card is never charged. After the trial, slots are $20/mo each, and once you reach 15 slots EVERY slot drops to $15/mo (not just the new ones).

The Only API provides 200+ endpoints covering messaging, mass DMs, fan lists, earnings analytics, content scheduling, pay-per-view management, subscriber data, and tip tracking. All endpoints are available on every plan with unlimited calls — no premium tiers or locked features.

Yes. Our Growth and Starter plans support no-code integrations with Zapier, Make (Integromat), and n8n. Automate fan engagement, mass messaging, content posting, and analytics reporting without writing a single line of code. Connect to 5,000+ apps through our pre-built automation workflows.

Account safety is our top priority. We use residential proxy infrastructure, human-like request patterns, and intelligent rate limiting to protect every connected OnlyFans account. We have maintained a zero-ban track record across thousands of managed accounts. Your creator accounts are in safe hands.

The Only API is up to 80% cheaper than competitors like OnlyFansAPI.com — with no credits, no per-call fees, and no RPM limits. We offer unlimited API calls on every plan, 200+ endpoints, and no-code integrations that most competitors charge extra for. Plus, we include a free plan so you can test before you buy.

Yes — The Only API supports both OnlyFans and Fansly. Connect a Fansly account with email & password or an auth token and manage it from the same dashboard. Support for additional creator platforms is on our roadmap.
