COMPARISON
The Only API vs onlyfansapi.com — The Cheapest OnlyFans API for Agencies
Two REST APIs aimed at the same problem — managing OnlyFans accounts programmatically. The differences are in pricing model, endpoint coverage, and how heavy workloads get billed. Here is the honest OnlyFans API comparison.
TL;DR
Both products are real REST APIs for OnlyFans. onlyfansapi.com has been around longer in some developer circles. The Only API is meaningfully cheaper for any workload that polls or mass-messages, because we charge per connected account with unlimited calls instead of per-call credits. If your onlyfansapi.com bill is dominated by credit top-ups, switching usually pays for itself in a month.
Side-by-side comparison
Based on publicly available information as of 2026. We have linked to our own docs where verifiable; for onlyfansapi.com claims, refer to their current reference.
| Feature | The Only API | onlyfansapi.com |
|---|---|---|
| Endpoint coverage | 200+ documented REST endpoints across messaging, mass DMs, posts, vault, fans, subscribers, earnings, payouts, campaigns, and notifications. | Endpoint catalogue is published on their docs site. Coverage of less-common surfaces (vault, campaigns, notifications) varies — verify against their current reference. |
| API call limits / credits | Unlimited API calls on every plan, including the free tier. No credits, no per-call charges, no overage bills. | Public pricing has historically used a credit / per-call model. Heavy polling and mass-messaging workloads consume credits quickly. |
| Response time | Sub-50ms typical for cached endpoints; live endpoints proxy directly to OnlyFans without artificial throttling. | Performance varies by endpoint. We could not verify a public SLA as of 2026. |
| Multi-account support | Per-account pricing with isolated sessions, optional dedicated proxy per account, and one API key spanning every connected account. | Multiple accounts supported. Pricing structure for many accounts is best confirmed on their site. |
| Webhook delivery | HMAC-SHA256-signed webhooks with an exponential retry schedule (5s, 30s, 5m, 30m, 2h) and auto-deactivation after sustained failure. | Webhooks are offered. Retry schedule and signing scheme: refer to their current docs. |
| Pricing model | Transparent per-account flat fee — Free / $20 Starter / $15 Growth — with unlimited calls. | Credit-based / per-call tiers historically. Confirm current numbers on their public pricing page. |
| Free plan | Yes. 1 OnlyFans account, all 200+ endpoints, unlimited calls, no credit card. | Free trial historically advertised; check their site for permanent free tier availability. |
| Documentation | Public OpenAPI spec, interactive playground, code examples in 5 languages. | Public reference docs hosted on their site. |
| Support | Email on Starter; dedicated account manager + priority support on Growth. | Email / community support tiers per their plans. |
| Country of origin / team | Built and operated by Xcelerate Management Limited (New Zealand) — agency-operator founders. | Public team and HQ details: best confirmed on their own site. |
Where The Only API wins
No credits, ever
Credit systems penalize the workloads that matter most: polling for new fan signups, running mass DM campaigns, fanning out webhook events. We charge a flat per-account fee. Run as many calls as you want, including from staging environments.
Cheaper at any non-trivial volume
$20 per account on Starter, $15 per account on Growth, with unlimited calls. If your monthly credit spend on a competing API is higher than $20 × your account count, you are overpaying.
Broader endpoint surface
200+ endpoints covering every OnlyFans surface we have shipped against — including campaigns, vault, payouts, and notification streams that some competing APIs do not expose. See /onlyfans-automation for use-case examples.
Sub-50ms response on cached endpoints
We aggressively cache safe-to-cache responses (profile, plan, subscriber lists with short TTLs). Live endpoints proxy directly without artificial throttling. Your automations feel instant.
Webhooks built for production
HMAC-SHA256 signing, [5s, 30s, 5m, 30m, 2h] retry, auto-deactivate after sustained failure, per-CRM isolation. Fewer surprises on Sunday at 3 a.m.
Free plan with full endpoint access
Most APIs gate the interesting endpoints behind paid tiers. We do not. The free plan gets all 200+ endpoints with one connected account so you can verify the API works for your use case before paying anyone.
Where onlyfansapi.com might fit better
Honest call-outs — Google rewards comparison pages that admit when a competitor has merit:
You already have a stable integration
If your code is already running against onlyfansapi.com and your bill is small (a handful of accounts, low call volume), the migration effort might not pay back fast enough. Switching only makes sense when the savings or coverage justify it.
You prefer pay-as-you-go billing
Some teams genuinely prefer credit-based pricing because it maps to a usage spike. We do not offer that — we are flat per account. If predictable, low-volume, bursty usage is your pattern, credits can be a feature, not a bug.
Pricing comparison
The Only API: Free (1 account), Starter $20/account/mo, Growth $15/account/mo at volume — unlimited calls on every tier. onlyfansapi.com: credit / per-call tiers as published on their site. For polling-heavy or mass-message workloads, our flat fee almost always wins; for tiny, bursty integrations, run the math both ways.
