Ukuqinisekisa nezinhlelo

Ungabiza i-API ngaphandle kwesithonjana ngaso sonke isikhathi - izicelo ezingaziwayo zikhawulelwe yi-IP. Ukuthola i-quota ephakeme, elindelekile ngenyanga (nokusetshenziswa kokuthengiswayo), yenza isithonjana kwikhasi le-akhawunti yakho bese uyithumela ngenye yezindlela ezintathu:

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"

• Ikhululekile — i-anonymize (IP rate-limited) noma inkinobho ekhululekile enesibalo esincane sonyaka. Ayikho emakethe.
• Umthuthukisi — $9/ngonyaka — 10,000 ukuxhuma/inyanga, ukusetshenziswa kwezokuhweba.
• Ibhizinisi — $49/ngonyaka — 100,000 ukubiza/inyanga, ukudluliswa okuphambili.

Uma isithonjana sisebenzisa i-quota yenyanga, i-API ibuyisela i-HTTP 429 nephutha "quota_exceeded"; isithonjana esingaziwa noma esingasebenzi sibuyisela i-HTTP 401. Uhlelo lwe-E-Learning Ukulinganisa ikhasi.
