Simple, Transparent Pricing. NO CREDITS

The Only API is a third-party REST API for OnlyFans and Fansly. 500+ documented API operations cover messaging and mass DMs, fan and subscriber management, earnings and payouts, campaigns and tracking links, webhooks, automations, and data export — all under one API key, with flat per-slot pricing and no per-call metering. Built for agencies and developers.

Slots are $20/month per connected account, on OnlyFans or Fansly. Once you reach 15 slots, every slot drops to $15/month — not just the new ones. Every paid slot includes unlimited monthly API calls with no credits and no metering. A Free Forever tier with 1 account and 1,000 API calls/month is available for testing, with no card required. Agencies running 50+ accounts should contact sales for Enterprise volume pricing below $15/slot.

No. Once you have a paid slot, API calls on that slot are unlimited at the monthly level — no per-call charges and no credit system. The free tier is the only plan with a monthly call cap (1,000 calls/month; the API returns HTTP 429 once you hit it). A 1,000 requests/minute anti-flood limit applies to every plan, free and paid, to protect connected accounts.

As many as you need. The Free Forever plan includes 1 account. On Slots you connect as many accounts as you like — each connected account uses one $20/month slot, dropping to $15/month per slot once you reach 15. That covers agencies from 5 to 500+ creators, including the 15-50 range. At 50+ accounts, contact sales for Enterprise pricing below $15/slot. Each account carries its own proxy (which you supply on connect via the X-Proxy header) and its own managed session, so accounts stay fully isolated from each other.

Paid slots start with a 14-day free trial — full access to all 500+ documented API operations and unlimited monthly API calls. Cancel before the trial ends and your card is never charged. After the trial, slots are $20/account/mo, dropping to $15/account/mo once you reach 15 slots. The Free Forever plan needs no trial and no card — just register. It does not expire.

500+ documented API operations covering messaging and mass DMs, fan lists with tags and notes, earnings analytics and payout status, subscriber and transaction data (live plus zero-cost cached reads), campaigns and tracking links, PPV stats, webhooks and automations, and CSV/JSON data export. Every endpoint is reachable on every plan — there is no plan-based feature gating. Write actions (sending DMs, mass DMs) are OFF by default on every connected account; enable them per account with PATCH /api/crm/{crm_id}/accounts/{of_user_id}/polling {"allow_of_write_actions": true}.

Yes, on every plan including the free tier — there is no plan gating on webhooks or automations. Zapier, Make (Integromat), and n8n connect via our generic `webhook` automation action: point it at the catch-hook URL those tools give you. Discord, Slack, Telegram, send_dm, and tag_fan are also available as first-class action types. Note that custom webhook URLs are created with status 'pending' and start firing once approved — Discord, Slack, and Telegram URLs auto-approve instantly.

No provider can guarantee an account outcome. You bring your own proxy — every OnlyFans account connect requires an X-Proxy header, and each account keeps its assigned proxy for all subsequent calls (GET/PATCH /api/crm/{crm_id}/accounts/{of_user_id}/proxy). We provide request signing, session management, paced platform traffic, and a proxy reachability tester (POST /api/crm/{crm_id}/proxy/test), and we strongly recommend a dedicated residential proxy per account. Write actions (sending DMs, mass DMs) are OFF by default until you explicitly enable them. Operators remain responsible for platform terms, proxy quality and usage.

Flat per-slot pricing with no credits and no per-call metering — most competitors meter by call or by credit bundle, which gets expensive at agency volume. Paid slots have no monthly call quota; a per-minute anti-flood ceiling (1,000 requests/minute default, lower on auth and other sensitive routes) applies on every plan. You also get 500+ documented API operations across both OnlyFans and Fansly, and no-code integrations that most competitors charge extra for, plus a free plan so you can test before you buy.

Yes — The Only API supports both OnlyFans and Fansly, and Fansly data is normalized to the same response shapes as OnlyFans. Connect Fansly with email/username + password (2FA supported) or with existing session credentials (fansly_session_id + fansly_client_id) via POST /api/crm/{crm_id}/accounts/login/cookies. Two OnlyFans-only exceptions: creating payout requests, and per-campaign claimer enumeration. Support for additional creator platforms is on our roadmap.

Yes. The backend, the event engine and the dashboard are published under AGPL-3.0, and the self-hosted build carries no account limit and no call metering — the metering layer is removed from it, not raised. There is no licence fee. What changes is who carries the work: you provide the server, you run the upgrades (a stale install breaks when OnlyFans or Fansly changes), and support is community only — GitHub and Telegram, with no SLA. You still need one dedicated proxy per connected account, exactly as you would on a paid plan. Captcha solving is different: it is included in the price here, and self-hosted you open your own provider account and fund it yourself. Below roughly five connected accounts, self-hosting usually does not work out cheaper once the server, the proxies, the captcha credits and your own time are counted.
