|---|---|---|---|---|
| apiKey | string | Required | – | Your Rembg API key |
| inputImage | string | Buffer | { base64: string } | Required | – | Image file, buffer, or base64 payload |
| onDownloadProgress | (event) => void | Optional | – | Hook for upload progress events |
| onUploadProgress | (event) => void | Optional | – | Hook for download progress events |

Kuweka Mazingira Yako: Hakikisha kuwa una faili ya .env kwenye msingi wa mradi wako iliyo na ufunguo wako wa API.
Kuagiza Moduli Muhimu: Anza kwa kuleta kitendakazi cha rembg kutoka @remove-background-ai/rembg.js na moduli ya dotenv ili kushughulikia vigeuzo vya mazingira.
Kusanidi Simu za Maendeleo: Maktaba inatoa onDownloadProgress na onUploadProgress callbacks kufuatilia maendeleo ya uendeshaji wa faili. Katika mfano uliotolewa, tunaweka matukio haya moja kwa moja kwenye kiweko.
Sasa, hebu tuangalie kwa karibu sampuli ya matumizi:
// script.mjs file
import { rembg } from '@remove-background-ai/rembg.js';
import dotenv from 'dotenv';
// Load environment variables from .env file
dotenv.config();
// API_KEY will be loaded from the .env file
const API_KEY = process.env.API_KEY;
// log upload and download progress
const onDownloadProgress = console.log;
const onUploadProgress = console.log;
rembg({
apiKey: API_KEY,
inputImage: './input.png', //inputImage can be one of these: string | Buffer | { base64: string };
onDownloadProgress,
onUploadProgress
}).then(({ outputImagePath, cleanup }) => {
console.log('✅🎉 background removed and saved under path=', outputImagePath);
// if called, it will cleanup (remove from disk) your removed background image
// cleanup();
});
Kumbuka, kipengele cha kusafisha kinaweza kuitwa ikiwa ungependa kuondoa picha iliyochakatwa kutoka kwa diski yako baada ya kuondolewa kwa usuli.
Inaonyesha upau wa Maendeleo
Unapojumuisha huduma ya kuondoa usuli, mara nyingi ni vyema kuwapa watumiaji maoni kuhusu maendeleo ya ombi lao la kupakia au kupakua. Ili kuwezesha hili, unaweza kufafanua simu zako za onDownloadProgress na onUploadProgress. Simu hizi zote mbili zinakubali AxiosProgressEvent kama kigezo cha tukio. Kadiri ombi linavyoendelea, simu hizi za kurudisha nyuma huimbwa mara nyingi, huku kuruhusu, kwa mfano, kuonyesha upau wa maendeleo na kurekebisha urefu wake kulingana na maendeleo.

Matumizi ya Uanachama na Mikopo
Hurejesha lebo ya mpango wako, salio la mkopo lililojumuishwa na linalolipiwa mapema, na matumizi. Unaweza kuuliza swali kufikia mwezi wa kalenda ya UTC (urithi), kwa kipindi cha bili kilichopangwa kwa Mistari (kwa ufuatiliaji kupitia kusasisha), au kuorodhesha vipindi vya bili vinavyojulikana. Thibitisha kwa ufunguo wako wa API pekee.

Vigezo vya hoja
| Kigezo | Aina | Maelezo |
|---|---|---|
| year | number | Mwaka wa Kalenda (1–9999). Katika mwezi, mtumiaji wa funguo za Redis husoma:{uid}:app_usage:{year}:{month}. Ikiwa imeachwa (na periodStartUnix haitumiki), chaguomsingi kwa mwaka wa sasa wa UTC. |
| month | number (1–12) | Kalenda ya mwezi wa 1–12 (mkataba wa UTC hutumika kwa funguo). Ikiondolewa, chaguomsingi kwa mwezi wa sasa wa UTC. |
| periodStartUnix | number | Muhuri wa muda wa Unix kwa sekunde: mwanzo wa dirisha la bili. Husoma mtumiaji:{uid}:app_usage:cycle:{periodStartUnix} na api_usage:cycle:…. Haiwezi kuunganishwa na mwaka au mwezi. |
| expand | string | Bendera zilizotenganishwa kwa koma. Jumuisha billing_cycle ili kuongeza kitu cha billingCycle: kipindi cha sasa cha Stripe wakati billing_period_* ipo katika Redis, vinginevyo mwezi wa sasa wa kalenda ya UTC. Pia inafanya kazi na periodStartUnix kwa dirisha maalum. |
| includeBillingCycle | 1 / true | Sawa na kupanua iliyo na billing_cycle: imewekwa kuwa 1 au kweli ili kujumuisha kitu cha billingCycle. |
| listBillingCycles | 1 / true | Hali maalum: listBillingCycles=1 au marejesho ya kweli pekee { billingCycles: [...] }. Inachanganua Redis kwa funguo za mzunguko kwa mtumiaji huyu; vigezo vingine vya hoja vinapuuzwa kwa ombi hili. |
Usipite periodStartUnix pamoja na mwaka au mwezi - API inarejesha 400. Hali ya listBillingCycles ni tofauti na inapuuza vigezo vingine.
Orodhesha vipindi vya bili
Tumia hii kujaza menyu kunjuzi ya madirisha ya usajili yaliyopita na ya sasa (kila ingizo ni periodStartUnix unaweza kurudishwa na periodStartUnix=…). Nyakati za mwisho za kipindi zimekisiwa (kipindi kijacho huanza − 1, au mwisho wa kipindi cha sasa cha Stripe kwa kipindi amilifu).
curl --location 'https://www.rembg.com/api/membership-usage?listBillingCycles=1' \ --header 'x-api-key: YOUR_API_KEY_HERE'
Mfano wa jibu
{
"billingCycles": [
{
"periodStartUnix": 1774268612,
"periodEndUnix": 1776947012,
"appUsage": 120,
"apiUsage": 880
}
]
}Panga kipindi kipya zaidi kwanza. Kipindi kinaonekana ikiwa kuna ufunguo wa matumizi ya mzunguko au ikiwa ni billing_period_start ya sasa kutoka kwa Stripe webhooks.
Kitu cha Mzunguko wa bili
Wasilisha wakati upanuzi unajumuisha billing_cycle au includeBillingCycle imewekwa. Itumie kwa dashibodi: mpaka wa kusasisha, matumizi kwenye dirisha, na mikopo iliyosalia iliyojumuishwa.
| Sehemu | Maelezo |
|---|---|
| periodStartUnix | Mwanzo wa dirisha la bili (sekunde moja). Inalinganisha Stripe current_period_start wakati akaunti inasawazishwa. |
| periodEndUnix | Mwisho wa kidirisha cha sasa (sekunde moja), yaani, kabla tu ya usasishaji unaofuata - Mwisho_wa_muda_wa mstari wakati kulandanishwa. Sio sawa na tarehe ya kughairi usajili. |
| appUsage / apiUsage | Matumizi ya mkopo yaliyojumuishwa katika dirisha hili: wavuti/kihariri (programu) dhidi ya ufunguo wa API (api). usedIncludedCredits ni sawa na jumla yao. |
| includedCredits | Posho yako ya mkopo iliyojumuishwa (ya mpango) kama ilivyohifadhiwa katika Redis (wazo sawa na mikopo ya kiwango cha juu). |
| prepaidCredits | Salio la kulipia kabla (lililonunuliwa); haiweki upya kila kipindi cha bili. |
| usedIncludedCredits | Jumla ya matumizi imejumuishwa kwenye dirisha (programu + API). Matumizi ya kulipia kabla hayajaongezwa hapa. |
| remainingIncludedCredits | max(0, pamoja naMikopo - usedIncludedCredits) kwa muhtasari huu. |
| stripeBillingSynced | ni kweli wakati Redis ina billing_period_start/end kutoka Stripe ili dirisha lilingane na usajili wako; uwongo inamaanisha kuwa API ilirejea kwa mwezi wa kalenda ya UTC kwa kizuizi hiki. |
Hadi Stripe webbhooks zimeandika vipindi vya bili kwa mtumiaji, stripeBillingSynced inaweza kuwa ya uwongo na dirisha la billingCycle litafuata mwezi wa kalenda ya UTC. Baada ya kusawazisha, vikomo vya matumizi kwenye API ya picha vinalingana na vitufe sawa vya mzunguko.
Kwa "mikopo iliyotumika kabla ya kusasishwa tena", piga simu kwa expand=billing_cycle na utumie billingCycle.periodEndUnix kama mpaka wa kufanya upya, billingCycle.usedIncludedCredits (au appUsage + apiUsage), na billingCycle.remainingIncludedCredits. Ongeza Mikopo ya kulipia kabla ikiwa unataka salio la jumla linaloweza kutumika.
Mifano (cURL)
Matumizi kwa mwezi mahususi wa kalenda ya UTC
curl --location 'https://www.rembg.com/api/membership-usage?year=2026&month=3' \ --header 'x-api-key: YOUR_API_KEY_HERE'
Mzunguko wa sasa wa utozaji + uzuiaji kamili wa bili (urekebishaji umewekwa wakati kulandanishwa)
# Current subscription window + usage (renewal-aligned when Stripe is synced) curl --location 'https://www.rembg.com/api/membership-usage?expand=billing_cycle' \ --header 'x-api-key: YOUR_API_KEY_HERE'
Dirisha moja la kihistoria la utozaji kwa kuanza kwa kipindi (kutoka kwa listBillingCycles au Stripe)
# Specific billing period by Stripe period start (unix seconds) curl --location 'https://www.rembg.com/api/membership-usage?periodStartUnix=1774268612&expand=billing_cycle' \ --header 'x-api-key: YOUR_API_KEY_HERE'
Mfano JSON (pamoja na mzunguko wa bili)
Matumizi_ya kiwango cha juu cha programu na api_matumizi kila wakati huakisi ama mwezi wa kalenda ulioombwa au, periodStartUnix inapowekwa, kaunta za mzunguko huo. Wakati expand=billing_cycle imeachwa, billingCycle haipo.

Error Handling Guidelines
- Check HTTP status code 400 to identify validation errors
- Parse the
errorfield for the error message - Check for the
detailsarray when handling multiple validation errors - Use the
fieldproperty to map errors to specific request parameters
