Feature FAQs
How many endpoints are available today?
The platform currently exposes 89+ health and fitness endpoints for production-grade integrations.
What is the recommended production host?
`api.hefitapi.com` is the recommended direct host for full performance and feature coverage.
How does language selection work on requests?
Use optional query `lang` on both GET and POST URLs with values `en`, `fr`, `es`, `de`, `pt`, `ja`, `hi`, or `ar`.
Can this shared infrastructure handle high concurrency?
Yes. The public production infra is built for burst traffic and supports up to 80+ million monthly API hits.
