COMPARISON
The Only API vs Infloww — OnlyFans & Fansly API for Agencies, Compared
An honest, feature-by-feature look at the developer-first OnlyFans API from Xcelerate Management Limited — 200+ endpoints across OnlyFans and Fansly behind one normalized API — and Infloww's full-suite agency product. We compare endpoint coverage, pricing, multi-account support, webhooks, and where each tool genuinely wins.
TL;DR
Infloww is a full-suite OnlyFans management platform with a built-in chatter and scheduling UI — buy it if your team wants a turnkey product without engineering. The Only API is the developer-first alternative: 200+ endpoints across OnlyFans and Fansly behind one normalized API, unlimited calls on every paid slot, no credits, and transparent per-account-slot pricing — Free forever at $0 for one account, $20/month per slot on Slots ($15/month per slot at 15+), and custom Enterprise pricing for 50+ accounts. Buy it if you want to build, integrate, or own the data layer. Both products are honest at what they do; pick based on whether you need a UI or an API.

| Feature | The Only API | Infloww |
|---|---|---|
| Platform coverage | OnlyFans and Fansly, normalized to the same response shape — subscribers, transactions, and campaigns return identical schemas across both platforms, so your integration code does not branch per platform. | Positioned as an OnlyFans product. Confirm current Fansly support on their site. |
| Endpoint coverage | 200+ documented REST endpoints across OnlyFans and Fansly covering messaging, mass DMs, posts, fans, subscribers, earnings, payouts, vault, and campaigns. | Full-suite product. API access exists for some integrations — exact endpoint count is not publicly documented as of July 2026. |
| API call limits / credits | Unlimited API calls on every paid slot. The Free forever tier includes 1,000 API calls/month across all 200+ endpoints — no credits and no per-call charges on any tier. A 600 requests/minute anti-flood cap applies on every tier. | Publicly positioned as a managed product, not a metered API. Programmatic limits are not published on their public pricing page. |
| Response time | Cached endpoints (cached subscribers, transactions, and campaign data) serve without a platform round-trip, so they return in single-digit-to-low-double-digit milliseconds; live endpoints proxy directly to OnlyFans or Fansly without artificial throttling. | Performance is tied to in-app actions; no public API SLA we could verify. |
| Multi-account support | Per-account-slot pricing with isolated sessions, a dedicated proxy per account, and a single API key spanning every OnlyFans and Fansly account in your panel. | Designed for agencies — multi-account is a core feature. Pricing model is per-seat / per-creator on their public plans. |
| Webhook delivery | HMAC-SHA256-signed webhooks with [5s, 30s, 5m, 30m, 2h] retry schedule and auto-deactivation on repeated failure. | Real-time notifications inside the Infloww UI. Programmatic webhook delivery to your own URL is not a documented public feature. |
| Hosted MCP server | Point Claude, Cursor, or any MCP client at our hosted MCP server, authenticate with your existing API key, and query your OnlyFans and Fansly data in natural language. Write access is off by default and gated per panel. | No hosted MCP server we could find as of July 2026. |
| Pricing model | Transparent per-account-slot: Free forever ($0 — 1 account, 1,000 API calls/mo), Slots ($20/mo per slot, dropping to $15/mo per slot at 15+ slots, unlimited calls), Enterprise (custom pricing, dedicated infrastructure, custom SLAs, white-glove onboarding for agencies managing 50+ accounts). | Tiered subscription published on their pricing page; check their site for current numbers. |
| Free tier / trial | Free forever tier — 1 account, all 200+ endpoints, 1,000 API calls/month, no credit card required. Separately, the Slots plan offers a 14-day free trial with unlimited calls. | Free trial as advertised; no permanent free tier we could verify. |
| Documentation | Public OpenAPI spec at /api/openapi.json, interactive in-browser playground at /api-reference (no login required), with auto-generated client snippets for every major language and HTTP client. | User-facing help center; no public API reference we could find as of July 2026. |
| Support | Community support on Free; priority email support on Slots; white-glove onboarding and custom SLAs on Enterprise. | In-app chat / email support on paid plans. |
| Country of origin / team | Built and operated by Xcelerate Management Limited (New Zealand) — agency-operator founders. | Public team and HQ details are best confirmed on their own site. |
Where The Only API wins
OnlyFans and Fansly, one normalized API
Connect OnlyFans and Fansly accounts through the same login flow and query them through the same endpoints. Subscribers, transactions, and campaigns return identical response shapes across both platforms, so your integration code never branches per platform. Infloww is positioned as an OnlyFans product.
Developer ergonomics
Public OpenAPI spec at /api/openapi.json, an interactive in-browser playground at /api-reference that needs no login, signed webhooks, and auto-generated client snippets for every major language and HTTP client. If your team writes code, we are built for the way you already work — no scraping, no UI automation, no brittle workarounds.
Unlimited API calls on every paid slot
We do not meter requests on paid slots. Hammer the messaging endpoints during a campaign, poll subscriber lists every minute, run analytics jobs at 3 a.m. — your bill does not change. Pricing depends only on connected accounts. The Free forever tier includes 1,000 API calls/month so you can evaluate before paying; there are no credits or per-call charges on any tier.
Hosted MCP server
Point Claude, Cursor, or any MCP client at our hosted MCP server, authenticate with your existing API key, and query your OnlyFans and Fansly data in natural language. Write access is off by default and gated per panel. No competitor in this comparison ships one.
Transparent per-account-slot pricing
Free forever is $0 for one account with 1,000 API calls/month. Slots is $20/month per connected account slot, and every slot drops to $15/month once you reach 15+. Enterprise is custom pricing with dedicated infrastructure, custom SLAs, and white-glove onboarding for agencies managing 50+ accounts. Every tier unlocks the same 200+ endpoints — no feature gating, no upcharge for webhooks.
Webhooks that survive the real world
HMAC-SHA256-signed payloads, exponential retries (5s, 30s, 5m, 30m, 2h), per-CRM isolation, and automatic deactivation after sustained failure. Build automations on top of our event bus instead of polling.
200+ endpoints under one key
Messages, mass DMs, posts, vault, fans, subscribers, earnings, payouts, campaigns, notifications, and more — all behind one API key, spanning every OnlyFans and Fansly account in your panel. See our /onlyfans-automation pillar for use cases.
Founder-built, agency-operator team
We run agencies ourselves. Bug reports get triaged by people who feel the same pain you do. No support tier exists where your ticket gets ignored.
Where Infloww might fit better
We are not going to pretend Infloww has zero merit — that is dishonest and Google rightly penalizes it. Here is where they genuinely have an edge:
You want a turnkey chatter UI today
Infloww ships a polished end-user product designed to be opened by chatters and managers without engineering involvement. We ship an API plus integrations — if you do not have anyone who can build a UI or wire Make/Zapier, their product is closer to what you need on day one.
You want one tool for everything
Infloww bundles management, chatting, scheduling, and reporting under one roof. We are deliberately scoped: a clean API plus a lightweight CRM dashboard. If you would rather pay one bill and not stitch tools together, that bundling is real value.
Pricing comparison
The Only API is priced per connected account slot, and every tier includes all 200+ endpoints across OnlyFans and Fansly:
- Free forever — $0. 1 account, 1,000 API calls/month, no credit card required.
