Before you build
Is API access included in my plan?
API access is included with FansMetric Standard and Pro, and you can test the API during your free trial. Usage limits apply; see the documentation for request limits and usage information.
Does FansMetric handle the OnlyFans connection?
FansMetric maintains connected account sessions and authenticates requests on your behalf. Your application uses a FansMetric API key. Accounts may need reconnecting if their session is lost.
Is the data live?
Most endpoints retrieve data from the connected OnlyFans account when requested. FansMetric-backed endpoints return data from FansMetric's database. The documentation identifies the source.
Can I control what an integration can do?
Yes. API keys use roles with per-route permissions, allowing you to grant the operations each integration needs.
Can I use the API alongside the CRM or AI Chatter?
Yes. Build custom integrations while using FansMetric's existing tools. You can also build your own AI chatter through the API. FansMetric AI Chatter has separate access and pricing terms.
