COMPARISON
The Only API vs Infloww — OnlyFans API for Agencies, Compared
An honest, feature-by-feature look at the developer-first OnlyFans API from Xcelerator 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, unlimited calls, no credits, transparent per-account pricing starting at $0 — 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.
Side-by-side comparison
Based on publicly available information as of 2026. We have linked to our own pages where verifiable; for Infloww claims, refer to their official site for current details.
| Feature | The Only API | Infloww |
|---|---|---|
| Endpoint coverage | 200+ documented REST endpoints 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 2026. |
| API call limits / credits | Unlimited API calls on every plan. No credits, no per-call fees, no overage bills. | Publicly positioned as a managed product, not a metered API. Programmatic limits are not published on their public pricing page. |
| Response time | Sub-50ms typical response for cached endpoints; live endpoints proxy directly to OnlyFans. | Performance is tied to in-app actions; no public API SLA we could verify. |
| Multi-account support | Per-account pricing with isolated sessions, optional dedicated proxy per account, and a single API key spanning every 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. |
| Pricing model | Transparent per-account: Free (1 account), Starter $20/account/mo, Growth $15/account/mo at volume. | Tiered subscription published on their pricing page; check their site for current numbers. |
| Free plan | Yes — 1 OnlyFans account, all 200+ endpoints, unlimited API calls, no credit card. | Free trial as advertised; no permanent free tier we could verify. |
| Documentation | Public OpenAPI spec, interactive playground, code examples in 5 languages. | User-facing help center; no public API reference we could find as of 2026. |
| Support | Email support on Starter; dedicated account manager + priority support on Growth. | 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
Developer ergonomics
Public OpenAPI spec, interactive playground, signed webhooks, and code examples in five languages. 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, no credits
We do not meter requests. 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.
Transparent per-account pricing
Starter is $20 per account per month, Growth drops to $15 per account at volume, and the Free plan covers one full account. Every plan unlocks the same 200+ endpoints — no feature gating, no enterprise upcharges 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, with multi-account support out of the box. 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 per-account with unlimited API calls: Free (1 account), Starter $20/account/mo, Growth $15/account/mo at volume. Every tier includes all 200+ endpoints. Infloww publishes its own tiers on their site — check both for your exact account count before deciding.
