Simple, Transparent Pricing. NO CREDITS

The Only API is a third-party REST API for OnlyFans and Fansly. 200+ endpoints 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 600 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 200+ endpoints 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.

200+ endpoints 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.

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, human-like request pacing, 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 also OFF by default on every connected account until you explicitly enable them. We have maintained a zero-ban track record across the accounts managed on the platform.

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 (600 requests/minute default, lower on auth and other sensitive routes) applies on every plan. You also get 200+ endpoints 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.
