Kutsimikizira & maphunziro

Mukhoza kufunsa API popanda chida chilichonse - zopempha zosadziwika zimatha kukhazikitsidwa ndi IP. Kuti mupange ndalama zowonjezereka, zoyembekezeka (ndi ntchito zapachuma), yambitsani chida patsamba lanu la akaunti ndikutumiza imodzi mwanjira zitatu:

GET  https://calculator.free/api/v1/mortgage/?price=350000&key=YOUR_KEY
curl -H "Authorization: Bearer YOUR_KEY" "https://calculator.free/api/v1/bmi/?units=metric&height=180&weight=80"
curl -H "X-Api-Key: YOUR_KEY"           "https://calculator.free/api/v1/bmi/?units=metric&height=180&weight=80"

• Wosuta — Kugwiritsa ntchito chida ichi kumatha kukhala kopanda dzina (IP yokhala ndi mtengo wotsika) kapena chida chosalipira ndi ndalama zochepa za mwezi.
• Wopanga & mdash; $ 9 / mo — 10,000 mafoni / mwezi, kugwiritsa ntchito malonda.
• Ntchito — $49 / mwezi — 100,000 mafoni / mwezi, cholinga kudzera.

Ngati chida cha mwezi chimagwiritsa ntchito ndalama zokwanira, API imatumiza HTTP 429 ndi vuto la "quota_exceeded"; chida chosadziwika kapena chosagwira ntchito chimatumiza HTTP 401. Onani zolinga zonse ndi kulembetsa pa Kugulitsa tsamba.
