🔌 I-Calculator API

Umbono

I-API isebenzisa i-matematics efanayo ne-website esebenzisayo. Thumela amaxabiso endawo ye-calculator njengezilungiselelo zombuzo noma i-JSON bese uthola izimpendulo ezibalolwe emuva njenge-JSON — kufaka phakathi noma yisiphi isikhashana sokubuyiselwa noma i-data ye-chart i-calculator ekhiqiza.

• 198+ ama-calculators, ngayinye inesimo sayo sokuphela
• Akukho kinomsindo we-API — anonymous access, rate-limited by IP
• CORS — Access-Control-Allow-Origin: * (usayizi ofanele)
• Izinga lokukhawulela: 60 izicelo/ihora ngalinye le-IP (HTTP 429 uma kudlula)
• Iphutha likhululekile — kuphela uphendule ophumelelayo (2xx) sebenzisa umlayezo owodwa kusuka ku-quota yakho yenyanga. Wonke 400, 401, 404, 429 ne-500 awudingi lutho.

Isisekelo URL

https://calculator.free/api/v1/

Isingeniso - thola uhlu lwazo zonke izibalo

GET https://calculator.free/api/v1/

Ibuyisela uhlu olufundeka ngemishini lwazo zonke izibalo ezinama-fields (isinqumo, isiphawuli, uhlobo, okuzenzakalelayo, isiyunithi) kanye nemiphumela yesinqumo - okunembile ukuthuthukisa umxhasi ngokuzenzakalela. Indawo ngayinye ifaka neflegi edingekayo — iqiniso kuma-fields ambalwa angeke abe nephutha (izinsuku, ikakhulukazi). Thumela lezi: ama-calculators ambalwa angasho eyodwa, okunye impendulo 400 ngaphandle kwayo.

Linganisa — sebenzisa i-calculator eyodwa

GET  https://calculator.free/api/v1/<slug>/?field=value&field=value
POST https://calculator.free/api/v1/<slug>/     (JSON or form body)

Uhlobo lwesinqumo:

{
  "ok": true,
  "slug": "mortgage",
  "country": "us",
  "inputs":   { ... the values actually computed with ... },
  "results":  { ... computed result keys ... },
  "schedule": { "columns": [...], "rows": [...] } | null,
  "chart":    { "type": "pie", "slices": [...] } | null,
  "defaults_applied": ["tax", "insurance"]
}

I-calculators eyaziwayo yezwe (i-mortgage, i-loan, i-income-tax, i-sales-tax…) ivunyelwe ?country=us|uk|ca|au|in|ie|nz|za. Isihlungi esingaziwa sibuyisela 404; izwe elingaxhaswa noma isingeniso esibi sibuyisela 400 nomlayezo osiza kanye nendawo ecacisiwe.

Amapharamitha, amaphutha namaphutha

Thumela kuphela ama-fields owaziyo. Noma yini ongayishiya ngaphandle igcwele nge-default eshicilelwe ye-field - ixabiso elifanayo ikhasi le-calculator ligcwalisa, ngakho-ke i-API ne-website zihlala zibuyisela inani elifanayo le-inputs. Uphendulo ngalunye lubonisa ukuthi yini egcwele ngaphansi defaults_applied.

Noma yini i-API engaxazululi ngokuvumelana nayo iyiphutha, ayikho i-zero: ipharamitha ebhalwe kabi, ixabiso lohlobo olungalunganga, isinqumo sokukhuphuka esingaziwa, noma indawo elahlekile engasebenzisi iphutha (izindawo zosuku - usuku lokuzalwa alukwazi ukucashunwa). Zonke i-400 zibiza ipharamitha elimazayo futhi ziphinde

$ curl "https://calculator.free/api/v1/mortgage/?price=350000&rate=6.5&term=30"
{
  "ok": false,
  "error": "unknown_parameter",
  "message": "Unknown parameter 'term' for calculator 'mortgage'. Did you mean 'years'? ...",
  "unknown_parameters": ["term"],
  "did_you_mean": { "term": "years" },
  "valid_parameters": ["down", "extra", "extra_onetime", "extra_yearly", "hoa",
                       "insurance", "other", "pmi", "price", "rate", "tax", "years"],
  "fields": [ ... ]
}

I- /api/v1/ isibalo sishicilela isici somhlaba wonke, uhlobo, isibalo, okuzenzakalelayo kanye nokuthi ngabe kudingeka — okunembile ukuthuthukisa umxhasi ongazange acabanga.

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 ene-quota encane ngenyanga. Ayikho emakethe.
• Umthuthukisi — $9/ngonyaka — 10,000 ukuxhuma/inyanga, ukusetshenziswa kwezokuhweba.
• Ibhizinisi — $49/ngonyaka — 100,000 ukubiza/inyanga, ukudluliswa okuphambili.

Izinto ezibangelwa i-quota yakho

Umbuzo ophumelelayo kuphela owenza lokhu. 2xx eyodwa = ucingo olulodwa. Iphutha ngalinye likhululekile: i-400 yepharamitha ebhalwe kabi, ixabiso elibi noma indawo edingekayo elahlekile, i-404 ye-slug engaziwayo, i-401 yeqhosha elibi, i-429, noma yini ehamba kahle engxenyeni yethu. Thola isivumelwano futhi lungisa isicelo sakho izikhathi eziningi njengoba ufuna — ukhokhwa ngemibuzo, hhayi ngezixazululo.

Ngenxa yokuthi iphutha likhululekile likhawulelwe ngezinga endaweni: uma inkinobho eyodwa ibangela okungaphezu kwe 200 iphoqeleke ukuphendula ngehora, ithola i-HTTP 429 "too_many_invalid_requests" kuze kube yihora lidlula. Izinhlamvu eziphumelelayo azikho ezibalayo, ngakho-ke ukuhlanganisa okusebenza ngeke kubone - ithola kuphela umxhasi okhubazekile ekwenzeni ukuphindaphinda.

Uma isithonjana sisebenzisa i-quota yenyanga, i-API ibuyisela i-HTTP 429 nephutha "quota_exceeded"; isithonjana esingaziwa noma esingasebenzi sibuyisela i-HTTP 401. See full plans and sign up on the Ukulinganisa ikhasi.
